Planets? What are planets? Why do they revolve under their own axis? These types of questions will be answered.

Well a planet begins just like a star except the matter is much smaller. They revolve for long periods of time then when they. Planets are great balls of interstellar matter that are much less in size than sun. The reason they revolve around their own axis is because according to Newton's first law of motion (that something in motion will stay in motion until acted upon by a outside force) the planet will keep revolving until something stops it. As you might already know that a planet revolves around the solar system. It revolves is because the sun's gravity is pulling it. In order to not get sucked in it will rotate around the sun. Going aside from the topic did you know that gravity is the weakest force out of all the four forces. Going back to the topic. Going to the next stage after the rotation the planet starts to heat up because everything starts getting condensed. Now the planet is in crucial stage if something breaks it apart it is gone forever. If nothing happens then the thing cools then hardens and becomes a planet. The planet is cooled from the outside but the inside extremely hot. That is all I know right now if I get something new I will update it.
