Double stars, also called binary stars, are valuable to astronomers because they are the only stars of which astronomers can easily calculate their mass. They are bound to each other by gravity and orbit about a common center. The time it takes for one star to orbit the other depends on the distance between the two stars and their masses.

What are Binary stars used to determine?
The masses of the two stars.
Stars that are found in pairs are called?
Two stars orbiting each other are "binary stars" ...a group of stars near each other, may be formally or informally known as a "cluster".
What percentage of stars are binary stars?
Roughly half of all stars in the galaxy are estimated to be part of binary or multiple star systems. This means approximately 50% of stars are binary stars.
What are stars found in pairs called?
A binary star is a system of two stars gravitationally bound together that are constantly orbiting each other.
Color of binary star?
Binary stars can appear in a variety of colors depending on the characteristics of the individual stars. The colors can range from blue or white for hotter stars to red for cooler stars. The combination of these colors can create unique visual effects when viewed together in the sky.
To calculate the mass of a star scientists study?
the orbits of binary stars
How is a binary used?
Binary what? Binary numbers? Binary stars? Binary fission?
What is the application of Kepler's third law in the study of binary stars?
Kepler's third law is used in the study of binary stars to determine the masses of the stars based on their orbital periods. By observing the motion of the stars in their orbits, scientists can apply Kepler's third law to calculate the masses of the stars and understand their gravitational interactions.

What colors are binary stars?
Binary stars can be any color that stars can be. There's no need for the two stars in a binary to be the same color.

Roughly half of all stars in the galaxy are estimated to be part of binary or multiple star systems. This means approximately 50% of stars are binary stars.
What are two stars bound by gravity called?
Binary stars
How many stars make up binary star?
By definition, a binary star system has two stars in it.
Which property of a star can be determined from binary star system?
The mass of a star can be determined from a binary star system, specifically by measuring the orbital motion and interaction between the two stars. This allows astronomers to apply Kepler's laws of planetary motion to calculate the masses of both stars in the system.
What do the orbits of binary stars tell about stars?
Binary stars are very useful for determining the mass of the stars and thus any objects orbiting around them.
What is a binary protostar?
"Binary" means there are two stars. And "protostar" means the stars are in an early, or preliminary, stage.
