wats a binary system?

Answer 1

A binary system is an astronomic term referring to two objects in space (usually stars, but also planets or asteroids) which are so close that their gravitational interaction causes them to orbit about a common center of mass.

Answer 2

A binary star is a stellar system consisting of two stars orbiting around their center of mass. For each star, the other is its companion star. Recent research suggests that a large percentage of stars are part of systems with at least two stars. Binary star systems are very important in astrophysics, because observing their mutual orbits allows their mass to be determined. The masses of many single stars can then be determined by extrapolations made from the observation of binaries.

Binary stars are not the same as optical double stars, which appear to be close together as seen from Earth, but may not be bound by gravity. Binary stars can either be distinguished optically (visual binaries) or by indirect techniques, such as spectroscopy. If binaries happen to orbit in a plane containing our line of sight, they will eclipse each other; these are called eclipsing binaries.

The components of binary star systems can exchange mass, bringing their evolution to stages that single stars cannot attain. Examples of binaries are Algol (an eclipsing binary), Sirius, and Cygnus X-1 (of which one member is probably a black hole).

Answer 3

A binary star or binary system is two stars orbiting each other. The Sun is all alone, but many stars are really pairs of stars orbiting each other, but they are so far away we see them as a single point of light without a telescope.

Answer 4

In astronomy, it refers to any stellar system containing two stars in the same orbit (or possibly, one orbiting the other).

Answer 5

Two stars that orbit around a central point due to gravity.

Answer 6

a numeral system using two symbols typically 0 and 1

Answer 7

A solar system that has two stars (suns).
