The solar system is the eight planets and all their moons in gravitational orbit around our sun. There are also many different objects in our solar system including asteroids, meteoroids, and they occasional comet. These worksheets take a deep dive into learning more about our solar system.
When you look around you see a world full of life. However, it is not the only world. Our world is just a fraction of the entire universe. The universe is composed of several galaxies and galaxies are composed of several solar systems. Our world is just a mere insignificant part of this huge and gigantic universe. The solar system that we live in is made up of several different elements. The most important part of our solar system is the Sun, which is a star. The other smaller objects revolve around the sun. The important objects after sun are the planets. There are eight major planets that revolve around the sun in this solar system. The planets that are closest to the sun are also the smallest. The four smallest planets near the sun are called Mars, Mercury, Venus, and Earth. Earth is the planet in which we reside.
There is an asteroid belt after that come these planets. Asteroids are the leftovers of planets. These millions of rocky objects revolve around the sun. They were formed around 4.5 billions of years ago. After the asteroid belt comes the rest of the four planets. These four planets are the largest and are known as the gas giants. They are huge in size but very less in weight. They are mostly made of hydrogen and helium. After these planets comes the tiny little planet Pluto. It is the furthest away from the sun. This is why Pluto is the coldest of them all. Pluto is even smaller than the Earth's moon. Astronomers believe that it is too small to be called a planet.
