Pluto discovered in 1930. It is small and frozen. It has one satellite. It turns around the sun every 249 years. Pluto is smaller than 7 of the moons in the Solar System. Because it is so small many scientists don't consider it a planet at all.

Jupiter is the biggest planet in the solar system. It has 16 satellites. Its turn around the sun lasts less than 12 years. You can see four of Jupiter's moons with a pair of binoculars at night. Also Jupiter spins really fast. It only takes 10 hours to go from night to day on Jupiter. For that reason its middle has been stretched out. Rather than round it is short and fat.

Mars



Mars is th planet after the Earth. it is also called the "Red Planet". It was believed to have had life. It contains polar domes of carbon dioxide. It turns around the sun every 687 days. It ahs two satellites: Phoboas and Deimos.

Venus is the shiniest, also known as "The Star of Dawn". It is slightly smaller than the earth. It turns around the sun every 225 days. Like the Earth, Venus has an atmosphere. However, this atmosphere is far thicker than that of the Earth, making it difficult for modern science to penetrate.
