Binary Star Systems

what are Binary Stars

Binary Star Systems are one of the most fascinating celestial phenomena in the universe.

These systems consist of two stars orbiting around each other, held together by the gravitational force of their combined masses.

The study of binary stars has greatly contributed to our understanding of stellar evolution and has helped astronomers to refine our knowledge of the basic properties of stars, such as mass and luminosity.

Binary star systems come in a variety of types.

Including those composed of two main sequence stars, to those with one giant and one dwarf star. They also exhibit a range of behaviors, including eclipsing, symbiotic, and cataclysmic variables. Furthermore, binary star systems are important because they offer a unique opportunity to measure the mass of stars in a direct way, a task which is much more challenging for single stars.

It is certain that binary star systems will continue to play a major role in our understanding of the cosmos, and we will undoubtedly discover many more fascinating and unexpected features of these amazing objects in the years to come.

How far is the nearest one from Earth?

The closest Binary Stars to Earth are called Alpha Centauri A and Alpha Centauri B. Interestingly they are part of a Triple Star System called Alpha Centauri and this is also the nearest Star System to Earth.

The Alpha Centauri System also contains a third star that was only discovered In 1915 by the Scottish Astronomer Robert Innes (Director of the Union Observatory in Johannesburg, South Africa). He discovered a star that had the same proper motion as Alpha Centauri and he suggested that it be named Proxima Centauri (actually Proxima Centaurus).

Proxima Centauri is the Closest Star to our Sun

Proxima Centauri is a dim star with a magnitude of 11.05, so it’s usually too faint to be seen with the naked eye. However, Proxima Centauri is a “flare star,” meaning it’s prone to sudden bursts of brightness resulting from magnetic activity and this does give rise to powerful phenomena that can sometimes be seen here on Earth.

In 2019, researchers spotted one of the largest stellar flares ever recorded in the Milky Way emerging from Proxima Centauri – The jet of plasma, which lasted just 7 seconds, was around 100 times more powerful than any flare ever seen emerging from the sun. The first Proxima Centauri superflare was actually spotted in 2016 and was bright enough for observers to spot it with the naked eye in dark sites on Earth.


Did you know you can Name a Binary Star?

Introducing a truly special gift

Name a Binary Star, as you get to put 2 name 2 stars and have these names placed onto the Binary Star Deed.

It is a perfect to give to a special couple or two people.  Or even to give to a partner.
