As a star runs out of nuclear fuel, some of its mass flows into its core. The core becomes to heavy and collapses on itself which results in a huge explosion called a supernova.

What's the difference between a planet and a dwarf planet? 

# data[].attributes.body
A planet is a ball of matter that has enough gravity to catch other objects into its gravitational field. A dwarf planet doesn't have enough gravity to even hold a probe in its gravitational field. Pluto only has a moon because they are orbiting each other.

Alpha-Centauri is part of  triple star system. The two main components are Alpha Centauri A and Alpha Centauri B. The third star is a red dwarf called Proxima Centauri and this star system is thought to be 4.22 light years distance and is our sun's closest neighbor among the stars. Scientist think that Alpha-Centauri can hold life because of how the conditions are almost perfect for a star system to hold life. First, Alpha Centauri is a star system that scientist have kept their eye on to find any form of life. Scientist also say that they think that there is a chance there might be able to have life in this star system because of the conditions the solar system is in. In conclusion, it is possible for Alpha-Centauri to hold life because of what perfect conditions the star system is in.

Will the sun ever die out?
Answer: Yes, the sun will die out eventually like every star. The sun is a G2U star, that is very very hot, providing enough heat for life hear on earth. The sun is a yellow dwarf, and is going to die out, but scientists predict us, and our very future relatives will never live in the time period when the sun dies out. But when the sun dies out, life here on earth will not live any longer, due to how much the sun provides.

Some say that we could live on Kepler 186F but we don't know for sure if we could or couldn't. We could because it's the right distance away from its sun and it's atmospher would help keep water on its surface liquid. then others say that water or liquid would freeze because it's on the outer edge of the habital zone so we could or couldn't. we need to find more information first to know for sure.
