Gravity and the Solar System How Did It Form?

1. Alternative Assessment By: Samantha Towle, Kaylee Sink, and CarlyPhilipps Gravity and the Solar SystemHow Did It Form?

2. The Solar System Our local star, the Sun, and everything that circles around it is known as the Solar System. The Sun’s gravity makes planets, asteroids, comets, and other bodies orbit in oval paths called ellipses. These ellipses orbit around the sun.

3. I know what your probably thinking. How did the Solar System form??? Well here we go.

4. HOW DID THE SOLAR SYSTEM FORM? It all started off by one thing the Solar Nebula. The Solar Nebula is a huge gas swirling cloud. The clouds collapsed under its own gravity into a fast-spinning, ball-shaped mass. The center part became thicker and hotter and eventually became a shining bright star, the Sun. Rocks, dust, and gases circling in a disk around the Sun began lumping together, and eventually it formed the planets.

5. The Planets & Ellipses A planet is a world that orbits a star. There are eight planets circling around the Sun. There are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. They each take different amounts of time to orbit the Sun. They orbit the sun in ellipses. Thanks to Kepler’s first law that stated “the orbits of the planets are ellipses, with the Sun at one focus of the ellipse.” Ellipse

6. Aphelionand Perihelion The difference of Aphelion and Perihelion is that Aphelion is when a planet is away from the Sun and that is when its Summer. When a planet is Perihelion its close to the Sun and its Winter.

7. A good way to remember Aphelion is Aphelion Away.

8. Gravity Gravity is another topic I should talk about. Gravity is a force of attraction between objects that is due to their masses and the distance between them. Gravity is what keeps planets, asteroids, comets, and other bodies in orbit around the sun. An example of gravity is what makes an apple fall out of a tree.
