We have 8 planets in our solar system . We also have 1 dwarf planet. We also orbit a star. All of our planets orbit the sun . There has never been a person on the sun. The reason why is because it is way to hot! Mercury is the closest planet to the sun . Mercury is the hottest planet in the in our solar system. Mercury is about the size of Earth’s moon. Venus is just about the same size of earth. On Earth you can actually see Venus. It is the third brightest object in space. Earth is the only planet with life on it. Its nick name is the Goldilocks planet. It also has the perfect amount of everything. Mars is the last inner plant . After Mars there's the asteroid belt. Even after that there's the outer planets. The asteroid belt surrounds the inner planets. Those planets are Mars , Earth , Venus , and Mercury. Those are the inner planets that are surrounded by the asteroid belt Jupiter is the biggest planet in the our solar system. It’s 11 times bigger than Earth. It also has 63 moons and counting . Saturn is one of the ring planets. It’s ring is visible from Earth! It is a gas giant . Uranus is another gas giant . It also rotates on its side . It has at least 27 moons. Neptune is mostly made out of hydrogen and helium. It is really windy at Neptune. Winds can reach up to 1200 mph… or higher. Pluto is not a planet anymore. It’s actually just a dwarf planet .
