Have you ever heard of Alpha Centaury? Maybe never heard. But today I will share a little bit info about this star system. This is a triple star system with it's 2 stars named Alpha Centauri (A and B). It's the closest star system and also the closest planetory system from earth's solar system. Its distance from the sun is about 4.37 light years. So, even if we travel at the speed of light, it will take us 4.37 years to get there.

In addition to these two stars(alpha A and alpha B, there is another star named Alpha Century C also known as proxima centaury. Distance from proxima centaury to sun is about 4.24 light years. Though other two stars are visible to the naked eye but alpha centaury C is not visible to the naked eye.
