How do these stars and planets form?
Gravity slowly pulls dust molecules around the star and are able to get them to come together and become 1 big pile of dust. Makes a Protostar
What happens when more gas joins in?
The temperature and pressure increases.
What happens when the temperature gets high enough. Specifically to the Hydrogen gas?
It makes the Hydrogen atoms fuse together releasing energy.
What dies faster a large star or a smaller star?
A large star because it burns through more of it energy a lot more faster than smaller stars.

LEO Satellite- LOW EARTH ORBIT satellite
GEO Satellite- Geosynchronous Earth Orbit satellite
What is a LEO Satellite?
It is used for imaging and rapid weather info. This moves around the entire Earth and orbits it, giving information like weather reports to those countres.
What is a GEO satellite?
Moves alone yet with the Earth. Same spot. Different amount for each country.
What is the life cycle of a Red Super giant Star?
