Thanks to advancements in technology in the last 100 years we can now look deeper into the Kosmos and explore planets and stars in more detail than ever before. NASA has even sent Rovers to far-off planets to explore their surface and probes that have left our solar system and are now hundreds of thousands of miles from our home planet.

There are 8 planets that orbit or move around our Sun and they are called : Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. These 8 planets can then be separated into two planetary categories, Terrestrial Planets and Gas Giants.

Our solar system is huge

The Sun isn’t the only thing in our solar system, of course. There are also planets, moons, asteroids, comets, and more. Our solar system is huge! And there’s still so much to learn about it. For example, scientists are still trying to figure out how the planets formed. So there’s definitely a lot to explore when it comes to our solar system.

Our Sun is actually a star

There are a lot of things to learn about our solar system. For example, did you know that the sun is actually a star? And that it’s the closest star to Earth? The sun is huge! It’s about 333,000 times the size of Earth. And it’s so bright that it’s hard to look at it with your bare eyes.

Gas Giant Planets

The four Gas Giants can be spilt again into a sub category called Ice Giants which consists of Uranus and Neptune due to their makeup being made up of large quantities of ice and rock.

Terrestrial Planets

The Terrestrial Planets consist of Mercury, Venus, Earth and Mars, and the Gas Giants which do not have solid surfaces are Jupiter, Saturn, Uranus and Neptune. The 4 Gas Giants can be spilt again into a sub category called Ice Giant which consists of Uranus and Neptune due to their makeup being made up of large quantities of ice and rock.
