Fascinating Facts about Stars

No one can quantify the number of stars in the known universe... yet if there are 100 billion galaxies, each one alone would contain 100 billion stars. All stars are red, white or blue and ironically the coolest stars are red and the hottest are blue. Also ironic...
The stars with the greatest mass will have a shorter lifespan. The sun is the sole star in our solar system, and this is the exception rather than the rule. Approximately 75% of stars subsist as part of a binary system, meaning two stars stand in orbit together. The distance between stars is staggering. Proxima Centauri is the second closest star to earth.
Located 4.2 light-years away or approximately 24 trillion miles away. Travelling to satellites is much more attainable. The moon is approximately 240,000 miles away. A white dwarf is a star going through a rather long extinction phase. Over a period of billions of years, they gradually emit less and less energy until they permanently go dark and shut down or self-destruct. Theoretical physicists suggest that the fallout from such an explosion creates a black hole.
