Star system
This article is about astronomy. For the Hollywood star system, see star system (film).
A star system or solar system is the area around a star (or a group of stars) which contains all of the planets, moons, asteroids, nebulae and other landmarks which are held in place by the star's gravity well.
Some of the star systems names were given to them years ago and those stars have kept their names. However, not all of the stars get their names from years ago, especially the stars that can’t be seen without a telescope.

Binary Star Systems
Versus Planetary Systems
Our Solar System may not be the norm for stars in the Universe. The observational evidence is that most stars are parts of multiple star systems, not single stars like our Sun.
The double star system comprises a star roughly three times more massive than our Sun with a less massive companion orbiting it at a distance of just 5.8 million miles (around six percent of the Earth-Sun distance).

Binary Star Systems
So far we have been able to determine distances, luminosities, temperatures and radii of stars. What about their masses? That is where binary star systems come into play.
A star system in which the stars are too close together to be visible separately. We see a single point of light, and only by taking a spectrum can we determine that there are two stars.

In a binary star system, each star moves around the other in an elliptical orbit. The point of maximum separation between the two stars is called the apastron.
In a double star system in which the two have significantly different masses (by far the most common), the higher mass star will use its internal hydrogen fuel the fastest and become a giant first.
The multiple star system zeta UMa (called Mizar - from the arabian word for girdle) belongs to the most famous multiple stars in the sky. It's brightness is about 2.

Now, any binary star system where the plane of the orbit is inclined toward us will show regular variations of the spectrum due to red and blue shifting of the spectrum.
If two stars orbit around one another, they form a binary star system. If three or more stars interact with each other, they form a multiple star system. In fact, over 50% of the stars are members of binary or multiple star systems.
This giant double star system is recognised as the most massive pair yet discovered.
periastron That point of the orbit of one member of a binary star system at which the stars are nearest to each other. That point at which they are farthest apart is called apastron.
Most star systems are binary. Binary systems are important because they allow astronomers to determine the masses of stars.
Barnard, Edward Emerson 1857-1923 American astronomer; discovered Jupiter's satellite Amalthea and Barnard's star, the second-nearest star system to the Sun. Barsoom The local name for Mars in Edgar Rice Burroughs' SF books.

Recognition that galaxies are independent star systems outside the Milky Way came from a study of the Andromeda Galaxy (1926-29) by Edwin P. Hubble that indicated the great distances at which this and other galaxies are located.
Suppose Alice is flying in a starship at half the speed of light to a star system ten light-years away. Alice's journey as seen by Bob on Earth would take 20 years.

A binary star is a double star system having orbital revolution components that cause the twin stars (so called because they usually form from the same interstellar cloud) to orbit each other around a shared center of mass due to the 'mutual gravity' ...
