Out of this world!!!. The Sun
The Romans called the sun Sol, which in English means sun. In ancient Greece, the sun was called Helios. Every planet in the solar system and Pluto rotate around the sun. The sun is not a planet and is actually a big star. The solar system is named after the scientific name for the sun, sol. The sun is definitely the largest thing in the solar system.
Pluto is a dwarf planet. People have said it isn't a planet, it’s actually a dwarf planet. A dwarf planet orbits the sun like any other planet, except it’s smaller. It is so small it can’t clear other objects out of it’s path.
Jupiter was King of the Roman Gods and the patron of the Roman state. To the ancient Greeks, he was known as Zeus, ruler of the Greek Gods and Mount Olympus. Jupiter is so big you could squeeze 1,000 earths in it. The swirls and bands you see around Jupiter are actually the top of clouds.
Venus is the Roman goddess of love and beauty. She is known as Aphrodite in Greek mythology. The planet is so named probably because it is the brightest of the planets known to the ancients. Venus is the second planet from the Sun, and the sixth largest of all the nine planets.
Saturn is the sixth planet from the Sun, and the second largest of the nine planets. Saturn's rings, unlike the rings of the other gas planets, are very bright.
When viewing Saturn through a small telescope, it appears a bit "squished." This is because its structure isn't very rigid (it's mostly gas and liquid), and it becomes slightly "compressed" as it spins very quickly.
Uranus is the seventh planet from the Sun and the third largest of the nine planets (in size). Uranus is larger in size but smaller in weight than Neptune. Uranus has been visited by only one spacecraft, Voyager 2 on Jan 24 1986.
Mars is sometimes referred to as the "Red Planet.” the largest mountain in the Solar System! Olympus Mons rises a full 24 km (78,000 ft.).
On Aug 6, 1996, David McKay announced the first identification of organic compounds in a Martian meteorite. It is suggested this may be evidence of ancient Martian life.
