The Solar System CS255 PowerPoint Presentation Stacy Stefaniak
Introduction • The Solar System is the sun and everything that orbits around it. • The Solar System is made up of the 9 planets, the sun, comets, and meteors. • The planets are separated into two groups: The Inner Planets and The Outer Planets based on how close they are to the sun.
The Sun • The sun is a star. It is the hottest, largest, and brightest object in our Solar System. • The sun is mostly made up of Hydrogen. • The sun is the start of our Solar System. It is very important to life on earth.
The Inner Planets Mercury Venus Earth Mars The Outer Planets Jupiter Saturn Uranus Neptune Pluto The 9 Planets
Mercury • Mercury is bare and rocky. • It has many craters and a lot of dust. • Mercury is the closest planet to the sun. • Mercury is the second smallest planet. • It can get up to 784F and as cold as –297F.
Venus • Venus has thick, yellow clouds made of poisonous Sulfuric Acid. • Venus is mostly flat with a few mountains. • There is very little water on Venus. • Venus is the hottest planet. It can get as hot as 900F.
Earth • Earth is the only planet that can have life. • 70% of the surface is covered with water. • Layers of gas surround the earth to protect life. • The earth has one moon.
Earth’s Moon • The moon is the second brightest object in the Solar System. • The moon doesn’t have an atmosphere. • The moon has highlands and craters. • FAQ’s about the moon– Moon Madness
Mars • Mars is known as the Red Planet. • Mars has many channels and craters. • People once believed life existed on Mars. • It has the largest volcano in the solar system. It is called Olympus Mons. • Mars has 2 moons.
Jupiter • Jupiter is the largest planet. • It is a ball of liquid, not solid like the first 4 planets. • Jupiter has many storms. The biggest one is called the Great Red Spot. These storms can last for years.
Jupiter’s Rings and Moons • Jupiter is surrounded by rings. • One ring is made up of pebbles, rocks, and boulders and another is made up of a ring of hot gas. • Jupiter has 16 moons. The largest is named IO. IO has many active volcanoes.
Saturn • Saturn is composed of gasses. • Saturn is the 2nd largest planet in the Solar System. • Saturn has clouds made up of frozen ammonia crystals. • The clouds can blow up to 1,000mph.
Saturn’s Rings • Saturn’s rings are over 160 thousand miles across. • The rings are wide, but they are only 50 miles thick. • The rings are not solid, they are made up of ice balls.
Saturn’s Moons • Out of all of the planets, Saturn has the most moon. It has 20. Scientists think it may have more. • Titan is the most interesting moon. It has a thick atmosphere and scientists think it may have water on its surface.
Uranus • Uranus was discovered in 1781. • Uranus is 4 times bigger than the earth. • Uranus is made up of gasses. • Uranus orbits the sun on its side. Why? Scientists believe it was hit by an object and tilted.
Uranus’ Rings and Moons • The rings of Uranus weren’t discovered until 1977! • There are 13 rings and they are chunks of an unknown black material. • Uranus has 15 moons. • On the moon Miranda, there are 3 mile high cliffs of ice.
Neptune • Neptune was discovered in 1846. • Until then, many scientists thought it was a star. • Strong, icy winds cover the planet in the form of storms. • Neptune is made up of liquid Methane gas.
Neptune has 2 rings, however there may be 5. They are made up of tiny frozen pieces of materials. Neptune has 8 moons. Triton is the biggest moon. Triton is colder than any other object in the Solar System. It has a temperature of –391F. It also has ice volcanoes that shoot Nitrogen ice and gas. Neptune’s Rings and Moons
Pluto • Pluto is thought to be the last planet in the Solar System. • We cannot get a clear view of Pluto because it is so far away. • Pluto was discovered in 1930. • Pluto has one moon, Charon. Charon is almost the same size as Pluto.
Asteroids • Asteroids are mini planets. They are chunks of rocks and metals that circle the sun. • The asteroids located between Jupiter and Mars are called the “Asteroid Belt.”
Meteors • When pieces of asteroids break off, they become meteors. • They streak through the sky toward earth. • When the pieces hit the earth, they are called meteorites.
Comets • Comets are patches of light that appear in the sky. • Comets are balls of dirt that circle the sun. • One of the main sources for comets is the Oort Cloud. • The Oort cloud surrounds the entire Solar System!
