Solar System PowerPoint By Kayley

Stars and our Sun A star is a huge ball of gas that is very hot and that gives off heat, light, and other energy that we need. Stars are classified by the elements that they absorb and their temperature.

Inner & Outer Planets Mercury -279 F at night and 801 F at day Diameter km or 3,032 ml Mercury is 28.5 million miles from the sun Mercury is a rock like planet Mercury's core makes up a larger portion of the planet surrounded by a mantle and crust. Mercury surprisingly has no moons unlike most of the other planets in our Solar System. Mercury only takes 88 days to orbit the sun because it is the closest to the sun. Saturn F Diameter 120,536 Kilometers or 74,898 mi million mi from the sun Saturn is a gas giant and it has no solid surface, it also has seven rings around it that are made of ice and rock. Saturn has a rocky core but it is considered a gas giant. Saturn is 1,503,000,000 km from the sun. Saturn has 62 moons Saturn is the sixth planet from the sun

Comets and Meteors Meteors are a small body of matter from outer space that enters Earth's atmosphere. Comets are a celestial object consisting of a nucleus of ice and dust. A meteoroid is a small particle from an asteroid or comet orbiting the sun. A meteor is a meteoroid that is observed as it burns up in the earth’s atmosphere. A meteorite is a meteoroid that survives its passage through the earth’s atmosphere and impacts the earth’s surface.

Gravity The force that attracts a body toward the center of the earth, or toward any other physical body having mass. For most purposes Newton's laws of gravity. Gravity impacts humans because without it people would float around and jump high without gravity pulling them down. Mercury is smaller than all the other planets in our Solar System, but it is dense. Because Mercury is so small, it has very little gravity. If you weighed 68 kg on Earth, you would only weigh 25.7 kg on Mercury.

Technology A rover is a space exploration vehicle designed to move across the surface of planets. Rovers impact humans because now we can look at mars and other planets without putting humans on the planets and risking there live because they don’t have enough food and water to stay.
