A Solar System Is Born(i dont believe a word of this but it was a good website page)
- Nebulas were the whole foundation of the solar system. They are the the large clouds of gas and dust that makes planets and stars.
- Gravity keeps nebulas together. It's more like the gravity in the nebulas is holding together but it's the same thing.
- Solar Nebula: The cloud of gas and dust that formed our solar system.
- This is how to solar system formed:
First the solar nebulas began to collapse. It actually took about ten million years to form the solar system. Once the nebulas collapsed, it became denser and the attraction between gas and dust particles increased. The center of the cloud became very hot. Then later over time the gas began to swirl slowly around the center. Over time it flattened out and the planets are still rotating like that today.
THE SUN
- The sun has six parts starting from the center in the order is : Core, radioactive zone, convective zone, photosphere, chromosphere, and corona.
- Energy in the sun is made from nuclear fusion. Nuclear fusion is the combination of the nuclei of small atoms to form a larger nucleus.

- During the process of nuclear fusion energy is made.
- Those large dark spot on the picture of the sun above is a sunspot. A sunspot is a dark area of the photosphere of the sun that is cooler than the surrounding areas and has a string magnetic field.

- There are three layers of the earth: crust, mantle, core.
- The oceans formed in earths second atmosphere. So about 4 billion years ago an ocean covered the whole world.

- Revolution is the motion of a body that travels around another body in space, so that describes the way our solar system rotates.
- Rotation is the spin of a body on its axis.
- An orbit is the path that something in space follows as it travels around another body in space
- Kepler's laws:
1)This discovery came from studying mars. Kepler learned that Mars did not move in a even circle and it was more of an ellipse. He discovered that planets don't always move in a circle around the sun.
2)This law is the law of motion. Kepler noticed that planets that moved around the sun moved faster than the ones farther away. To understand this, think of a string. The shorter the string is the faster it will go.
3)Explains the relationship between the period of a planet's revolution and its semi-major axis.
