Transcript of What is the life cycle of a Planet?
By Hudson Ash What is the life cycle of Planet? The Death of a Star A planet is formed when a star explodes into a Planetary Nebula explosion which also creates stars. The planet will either start off with a hard rocky surface or a Gas giant with no solid surface or even a icy planet with below absolute zero temperatures. A planets structure depends on what elements are within and out the planet. Earth has a searing hot core in the middle and the outer layer has a solid crust that we know is the land. The Sun has a core that is so big and hot that anything near it will burn up instantly as well as the surface. Planets like Jupiter are Gas giants that have no solid surface so if you fell into Jupiter you would fall straight through the planet. Stars Our Own Exo-Planets The Start Stars are a natural source of light in the universe that provide heat to a moon or planet orbiting it’s gravitational pull. Stars vary from different sizes and types. The smaller they are the more time they have to live. Small blue stars have a long life to live but the giant red stars are nearing the end. A star is a vital requirement in a planets life cycle. When a star reaches the end of its life it will turn into a Red Giant star. These stars are about 100 times their original size and they are dangerous. What happens is that when the star is converting Hydrogen into Helium it has a limited supply in the stars core. When this runs out the star cannot convert the to elements anymore so it grows a enormous size. This also means that the stars light does not exist anymore. After millions of years the star finally dies and causes a catastrophic explosion called a supernova. This also creates Planetary Nebula which is a giant cloud of gas and dust which creates thousands upon thousands of new stars inside the cloud. This cloud is extremely hot reaching well over 10,000 Celsius. After the explosion the star grows smaller and turns into a cold, dead White Dwarf star. A Planet that we can study that has a Full transcript
massive amount of living organisms in
our Solar System is our own: Planet Earth.
So far our planet is the only one we know of that is known to contain life. If we find another planet outside our solar system that has life on it we might find the origins of how our planet was formed. Exo-Planets are planets out side of our solar system.
There have been countless discoveries of them and
there are more than 5 types. One type is called a Super Earth. These planets are super sized Earth are believed to be full of gases similar to that of Jupiter, but could contain small life.
