What is a binary star system?

Answer 1

'Bi' means two(2) . So a Binary Star System is two stars rotating about each other. In space the star Procyon, in the 'Little Dog ' Comnstelltion is a binary system. Procyon A is the Main Star and it has procyon B revolving around Procyon A

They are commonly referred to as the Little Dog, and the Pup.

Much nearer to home, The Earth and the Moon are thought to be a planetary binary system, because our moon is so large, compared to other moons and planets, that the Earth moves against the Moon too!!!!!

Answer 2

A double star is a pair that appear very close together in the sky, but that might be by chance and one of them might in fact be a lot further away than the other. A binary star is a special type of double star in which the two components are in orbit around their common centre of gravity.

Answer 3

They are sometimes used as synonyms, but actually a double star is two stars that look as if they are close together, but may or may not be a binary star. That is, they may just happen to be in the same direction.

A binary star system is composed of two stars that are really connected, by gravity.

Answer 4

A binary star system is a system in which two stars are orbiting around a common center of mass. These stars are bound together by gravity and can orbit each other in various configurations, such as close binaries where the stars are very close together, or wide binaries where they are farther apart. Binary star systems are common in the universe.

Answer 5

A binary star system has two stars in the same system; our solar system has only one star.

Answer 6

A binary star system is another term for a binary star - a stellar system in which two stars orbit around their centre of mass - also known as a double star.
