Our solar system is situated in the Milky Way galaxy's outer spiral arm.
The sun, our star, and everything gravitationally connected to it, including the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, dwarf planets like Pluto, dozens of moons, and millions of asteroids, comets, and meteoroids, make up our solar system. Nasa has found hundreds more planetary systems orbiting other stars in the Milky Way in addition to our own solar system. So we are going to see all of these things step by step in this article.
The Sun keeps the solar system in placeby maintaining its orbit around everything, even the tiniest pieces of junk.
At the heart of our solar system, our Sun, a 4.5 billion year old star, is a hot, glowing ball of hydrogen and helium. The distance between the Sun and Earth is around 93 million miles (150 million kilometers), and without the Sun's energy, life as we know it would not be possible on our planet.
The biggest body in our solar system is the Sun. 1.3 million Earths would be required to completely fill the Sun. The largest planets and the smallest pieces of junk are all in orbit around it thanks to its gravity, which also binds the solar system together. The Sun's core, where temperatures may reach 27 million degrees Fahrenheit (15 million degrees Celsius), is the hottest spot on the planet. The Sun exerts an impact on the nature of space across the solar system through its tremendous eruptions and continuous stream of charged particles.
And now we are going to talk about our planets.
Four distinct, rocky planets, two intricate gas giants, and two far-off ice giants.
The Sun would look more than three times as big and up to 11 times brighter from the surface of Mercury as it does from Earth.
Mercury, the smallest planet in our solar system and the one closest to the Sun, is just a little bit bigger than the Moon.
The Sun would be visible from the surface of Mercury as being up to seven times brighter and more than three times as huge as it is from Earth. Mercury is close to the Sun, but Venus, which is also close by, has the record for being the hottest planet in our solar system.
From some areas of Mercury's surface, the Sun seems to momentarily rise, set, and rise again due to the planet's eccentric orbit (which resembles an egg) and slow spin. At sunset, the identical scenario plays out in reverse.
Venus is the hottest planet in our solar system because of its thick atmosphere, which traps heat in a runaway greenhouse effect. Venus is similar in size and structure to Earth.
The second planet from the Sun and nearest planetary neighbor to Earth is Venus. It is one of the four inner, rocky terrestrial planets and is frequently referred to be Earth's twin due to similarities in size and density.
There are significant variances between the two universes, yet these are not identical twins.
Venus is permanently cloaked in thick, yellowish sulfuric acid clouds that trap heat and contribute to a runaway greenhouse effect. Venus also has a thick, poisonous atmosphere that is packed with carbon dioxide. Despite Mercury being closer to the Sun, it is the planet with the highest temperature in our solar system. Venus's surface reaches temperatures of roughly 900 °F (475 °C), which are hot enough to melt lead. The surface is reddish in hue and covered in sharply compacted debris. big volcanoes, mountains, and thousands of them. There may still be some active volcanoes, according to scientists.
At its surface, Venus has crushing air pressure that is more than 90 times greater than that of Earth. This pressure is comparable to what you would experience a mile beneath the Earth's ocean.
Our home planet, Earth, is the only location we are currently aware of where there are living organisms. Additionally, it is the only planet in our solar system with surface water.
The only place we are currently aware of where there are living creatures is our home planet, which is the third planet from the Sun.

Why Does the Moon Occasionally Seem So Big? The Moon Illusion.
Earth is the only planet in our solar system having liquid water on its surface, while being just the fifth biggest planet overall. Earth is the largest of the four planets nearest to the Sun, all of which are composed of rock and metal, and is only slightly larger than adjacent Venus.
The English name of Earth is unique among the planets of the Solar System since it does not originate in Greek or Roman mythology.
The name was derived from Germanic and Old English. Simply put, it means "the ground." Of course, there are several names for our planet in the tens of thousands of languages that the inhabitants of the third planet from the Sun speak.
Mars is a cold, arid, dusty planet with a tenuous atmosphere. There is compelling evidence that Mars had a thicker atmosphere and was wetter and warmer billions of years ago.
Mars, a cold, dry, dusty planet with a thin atmosphere, is the fourth planet from the Sun. Along with having seasons, polar ice caps, canyons, extinct volcanoes, and indications that it was once far more active, Mars is a dynamic planet.
Currently, NASA is studying the Martian surface using two rovers (Curiosity and Perseverance), one lander (Insight), and one helicopter (Ingenuity).
On February 18, 2021, the Perseverance rover, the biggest and most sophisticated rover NASA has ever deployed to another planet, landed on Mars after a 203-day trek covering 293 million miles (472 million kilometers). The Perseverance's belly carried the Ingenuity helicopter as it traveled to Mars.
One of three spacecraft that reached Mars in 2021 is called Perseverance. On February 9, 2021, the United Arab Emirates' Hope orbiter touched down. China's Tianwen-1 mission, which consists of an orbiter, a lander, and a rover, touched down on February 10, 2021. India and Europe each have satellites orbiting Mars that are being studied.
With the landing of its Zhurong Mars rover in May 2021, China became the second country to ever successfully land on Mars.
Three NASA orbiters, the 2001 Mars Odyssey, the Mars Reconnaissance Orbiter, and MAVEN, are among the eight orbiters from different nations that are now observing the Red Planet from space.
These robotic explorers have discovered a ton of evidence that, billions of years ago, Mars was significantly wetter, warmer, and had a thicker atmosphere.
Compared to the other planets in our solar system combined, Jupiter is more than twice as big. The Great Red Spot of the enormous planet is an eon-old storm larger than Earth.
Since Galileo Galilei discovered the first moons outside of Earth in 1610, Jupiter has a long history of shocking astronomers. That finding altered our perspective of the cosmos.

Jupiter, the fifth planet from the Sun, is by far the biggest planet in the solar system, with a mass that is more than twice that of all the other planets put together.
The well-known stripes and swirls of Jupiter are actually ammonia and water clouds floating in a hydrogen and helium atmosphere. These clouds are frigid and windy. The famous Great Red Spot-on Jupiter is a gigantic storm that has been raging for hundreds of years and is larger than Earth.
The NASA Juno orbiter is the only spacecraft actively examining this enormous planet.
Saturn is distinctive in our solar system because of its brilliant, intricate system of ice rings. While the rings of the other large planets are impressive, none compare to those of Saturn.
The second-largest planet in our solar system, Saturn, is located at a distance of six planets from the Sun.
Saturn stands out among the planets due to its many lovely ringlets. While there are other planets with rings comprised of ice and rock fragments, none are as magnificent or intricate as Saturn's.
Saturn, a gas giant like Jupiter, is a large globe primarily composed of hydrogen and helium.
The seventh planet from the Sun, Uranus, spins over 90 degrees away from the equator. Uranus seems to rotate on its side because of its peculiar tilt.
In our solar system, Uranus, which is the seventh planet from the Sun, has the third-largest diameter. Despite first believing it to be either a comet or a star, astronomer William Herschel discovered Uranus in 1781, making it the first planet to be spotted with the use of a telescope.
Two years later, in part as a result of observations by astronomer Johann Elert Bode, the object was unanimously acknowledged as a new planet. Herschel made an unsuccessful attempt to give his find the name Georgium Sidus in honor of King George III. Instead, Bode's recommendation to name it after the Greek deity of the sky, Uranus, was approved by the scientific community.
The eighth and furthest giant planet from our Sun, Neptune is chilly, dark, and buffeted by supersonic winds. It was the first planet to be discovered using mathematics.
The eighth and furthest planet in our solar system is the ice giant Neptune, which is dark, frigid, and buffeted by supersonic winds.
Neptune is the only planet in our solar system that cannot be seen with the naked eye and was the first planet to be predicted by mathematics prior to its discovery. It is more than 30 times further from the Sun than Earth. Neptune's first 165-year orbit after its discovery in 1846 was finished in 2011.
The only spacecraft to have made a close encounter with Neptune is NASA's Voyager 2. In 1989, while it was leaving the solar system, it passed through.
And now we are going to talk about our moons
Earth's moon, the fifth biggest moon in the solar system, is the only other planet where people have ever set foot.
The only location mankind have ventured beyond Earth is on the Moon.
The Moon, the largest and brightest object in our night sky, stabilizes the Earth's axial wobble, which results in a generally constant climate. This makes Earth a more livable planet. Additionally, it brings about tides, which provide a rhythm that has aided people for countless years. A body the size of Mars likely collided with Earth and created the moon.
Of the more than 200 moons that circle planets in our solar system, the Moon on Earth is the sixth biggest.
Because no one knew there were any other moons until Galileo Galilei found four moons circling Jupiter in 1610, Earth's lone natural satellite is simply referred to as "the Moon".
Mars Moons
Phobos and Deimos are two of Mars' moons. Both are thought to be asteroids that were caught.
The biggest of Mars' two moons is Phobos. It makes three daily circles about Mars and is sometimes invisible on Mars because to its proximity to the planet's surface. At a distance of six feet (1.8 meters) per hundred years, Phobos is getting closer to Mars. At that speed, it will either disintegrate into a ring or collide with Mars in 50 million years.
The smallest of Mars' two moons is called Deimos. Every 30 hours, it revolves around Mars.
Jupiter Moons
Most estimates place the number of moons orbiting Jupiter at 80 and 95, however neither estimate fully expresses the intricacy of the Jovian system's moons, rings, and asteroids. Thousands of minor particles are in the large planet's orbit under its control.
The four biggest moons of Jupiter were the first extraterrestrial bodies to be identified. After the Italian astronomer Galileo Galilei, who first noticed them in 1610, they are known as the Galilean satellites. Galileo is credited with discovering the moons, even though German astronomer Simon Marius claimed to have observed them about the same time. However, Marius did not record his observations, therefore Galileo is given the credit.
- Io is the solar system's most volcanically active planet, with hundreds of volcanoes, some of which produce lava fountains that reach heights of several miles (or kilometers).
- Europa is believed to contain an iron core, a rocky mantle, and an ocean of salty water, making it one of the greatest spots in our solar system to search for life outside of Earth.
- Ganymede is the only moon in our solar system with its own magnetic field, and it is also the biggest moon there.
- Callisto is the solar system's object with the most craters.
Dust for Jupiter's four flimsy rings comes from four more of its innermost moons. The orbits of the other moons of Jupiter are substantially further from the planet. The smaller moons are probably pieces from severe impacts, whereas the bigger moons might be captured asteroids.
There are a lot of other moons in our solar system, but that's enough for now, so that we can move and learn about the asteroids, coments & meteors...
Asteroids
Asteroids, sometimes known as minor planets, are stony, airless debris from the early stages of the solar system's creation, which occurred around 4.6 billion years ago.
There are 1,298,586 known asteroids as of right present.
The main asteroid belt, which lies between Mars and Jupiter, is where the majority of this old space debris may be found circling the Sun. Vesta, the biggest asteroid, has a diameter of around 329 miles (530 kilometers), yet there are some things that are only 33 feet (10 meters) wide. All of the asteroids put together have less mass than the moon of Earth.
Meteors & Meteorites
All of them have something in common with the "shooting stars" that may occasionally be seen blazing across the sky. But depending on where it is, we refer to the same thing by different names.
Meteoroids are spacecraft that range in size from tiny asteroids to dust grains. Assume these are "space rocks."
Meteors are fireballs or "shooting stars" that form when meteoroids travel at a high speed through the atmosphere of Earth (or another planet, such Mars), then ignite.
A meteoroid is referred to as a meteorite when it makes it through the atmosphere and lands on the earth.
Comets
Comets are made of ice, rock, and dust and are frozen remnants of the solar system's genesis. They can be a few miles to tens of miles wide, but when they approach the Sun, they get hot and eject gases and dust into a luminous head that can be as big as a planet. This substance creates a tail that is millions of kilometers long.
Comets are solar system-orbiting icy balls of rock, gas, and dust. They resemble a small town in size when frozen. A comet's orbit takes it in close proximity to the Sun, which causes it to heat up and eject dust and gases into a massive blazing head bigger than most planets. A tail of gas and dust that extends millions of kilometers from the Sun is created. In the Kuiper Belt and the farther out Oort Cloud, there are probably billions of comets circling our Sun.
3,881 comets are now recognized as existing.
our solar system is incredible!! I hope you guys have learned about it from this article.
