They orbit about a common center of mass every 357 days, coming as close as 3 astronomical units to each other. The Beta Centauri A stars are what's known as B1 III stars; that's a stellar classification code that indicates that they are bright hot blue giant stars entering the latter stages of their stellar lifetime.9 Apr 2021
What kind of star is Beta Centauri?
B-type stars Beta Centauri, also called Hadar or Agena, second brightest star (after Alpha Centauri) in the southern constellation Centaurus and the 10th brightest star in the sky. Beta Centauri is about 390 light-years from Earth. It is a system of three B-type stars.
Is Beta Centauri A blue Giant?
Beta Centauri Aa and Ab are blue giant stars that are evolving away from the main sequence. Both stars are also Beta Cephei Variable stars – thus they have multiple pulsations of just a few hours.
Is Alpha Centauri A giant?
Their elliptical orbit is eccentric, so that the distance between A and B varies from 35.6 AU (astronomical units), or about the distance between Pluto and the Sun, to 11.2 AU, or about the distance between Saturn and the Sun. Alpha Centauri C, or Proxima Centauri, is a small faint red dwarf (Class M).
Is Alpha Centauri A Dwarf star?
Alpha Centauri A is a G dwarf similar to our own Sun. The newly detected signal originates from within the star's habitable zone, and implies the presence of a planet roughly five to seven times the size of Earth, orbiting Alpha Centauri at a distance of about one to two times Earth's distance from the Sun.
Is Hadar a red giant?
It has an apparent magnitude of 6.0 and lies at a distance of 3,960 light years. Hadar can also be used to find HR 5171 (V766 Centauri), a triple star system containing either a red supergiant or yellow hypergiant in an eclipsing binary system.
Is Beta Centauri a red giant?
The Beta Centauri A stars are what's known as B1 III stars; that's a stellar classification code that indicates that they are bright hot blue giant stars entering the latter stages of their stellar lifetime. Such massive stars tend to be short-lived, compared to lower mass stars like the sun.

Is there another solar system?
The Short Answer: Our planetary system is the only one officially called “solar system,” but astronomers have discovered more than 3,200 other stars with planets orbiting them in our galaxy. Our solar system is just one specific planetary system—a star with planets orbiting around it.
Is Mars habitable?
Ongoing findings from rovers, landers and orbiters suggest the planet was habitable – suitable for life – in the past. Of course, habitable doesn't mean inhabited.
