Yes, they can have planets but they will not be as common as a single star system. If any planets are formed, they will generally be far away from the stars.

This is because of the gravitational influences of two stars. This instability prohibits the formation of planets.

Obviously, it depends on the mass of the two stars and their distance from each other. A close pair will probably not have planets whereas a major star and a far minor binary pair will not experience the same influences and planet formation could occur without the same constraint's.

Our nearest binary/triple star system - Alpha Centauri has yet to have any planets detected.

Are there any planets located near the star algol?

At the moment no planets have been detected, which is not surprising as it's a binary star system (possibly triple star).


Does every star have a planetary system?

With current evidence, the answer is no. Whilst many stars will have a planetary system (Solar System) many will not. The prime candidates for not having any planets are binary and multiple star systems. This is because the gravitation tug of the multiple stars, inhibits planet formation. Our closest star system, Alpha Centaur which is a binary system, has failed to produce any planets, whereas further away stars have, This seems to suggest that the theory is at least partly true. Planets have been found in binary systems, but they are rare. So: Not all stars have planets.


What are the different kinds of solar system?

"solar system" is the term used to describe planets orbiting a star. We know that planets also orbit binary and tertiary star systems, these would be different kinds of solar systems.


What do we call a solar system with 2 stars?

Star system with 2 star called? binary star system


Is a star system containing two stars called a binary star?

Yes. No, it is called a binary system.


Color of binary star?

A binary star is not any particular color. A binary star system can contain stars of any spectral type.


What is a binary star system?

'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!!!!!


What is the solar mass of a binary star?

A binary star is simply a system containing two stars, which does not say anything about the system's mass.


Is vega star a part of a binary or multiple system?

No - it is a single star system


What is a member of a double star system?

A double star system consists of the two components in that system. A multiple star system consists of all the individual components in that system. A binary star or physical multiple system can be limited to the enumerated components. A broader definition could include all other material which is gravitationally bound to the system: planets, etc.


What is called as binary star or double star?

A binary star system is two stars that orbit around each other


Where is planet heaven is it in the polaris star system since polaris is a trinity star system?

Polaris is a Trinary star system, but there are many other trinary star systems out there, and to date no exo solar planets have been discovered around any of the stars that make up the Polaris system. Not to mention that Polaris A being a red giant and Polaris B and C being a close binary star system the existence of any planets is very unlikely.
