Binary and Multiple Stars
Double stars are stars that appear to be near each other in the sky, but if they’re gravitationally bound together we call them binary stars. Many stars are actually part of binary or multiple systems. If they are close enough together...

Types of Binary Star Systems
Our solar system has just one star in it, the sun. But this is actually not the most common situation for systems. Most systems are multi-star systems, with binary systems being extremely common. These are systems where two stars orbit...
