What is the size of vega star deneb star pollux star polaris star procynon star and alpha centauri star?
This is the order from smallest stars to the biggest stars: Alpha Centauri, Procyon, Vega, Pollux, Polaris, and Deneb. These are the size(diameter) of them; though the size of the stars are not 100% accurate so they are likely to be predicted. Alpha Centauri is 1,527,000 Procyon is 2,652,000 Vega is 3,827,000 Pollux is 11,617,000 Polaris is 44,217,000 and Deneb is 203,000,000
Is a giant Alpha Centauri?
No. Alpha Centauri is a three-star system consisting of two stars similar in size to the sun and a red dwarf.
What is the difference between Alpha Centauri A and Alpha Centauri B?
Alpha Centauri is a binary star system, commonly known as Alpha Centauri ABAlpha Centauri A is about the same size and age as our Sun with a spectral type of G2VAlpha Centauri B is about 14% smaller that our Sun and a lot cooler having a spectral type of K1VThere is a third star, not surprisingly called Alpha Centauri C or Proxima Centauri which is the closest star to Earth.See related link for more information.
What star is part of a triple star system?
The most famous triple star system is Alpha Ursae Minoris in the Ursa Minor constellation. Approximately 325 light years away. It is commonly known as the North Star or Polaris. 3 stars make up this system: Polaris, Polaris AB and Polaris B.Another somewhat famous 3-star system is Gliese 667 in the Scorpius constellation about 22 light years away with Gliese 667 A, B and C. This system is also home to a potentially habitable super-Earth, Gliese 667Cc at at least 4.5 times the size of Earth.Another well known triple system is the Alpha Centauri system. (It is still not certain that Proxima is actually physically part of the Alpha Centauri system or simply very close to it.)
What star is very similar to sun?
Alpha Centauri is the nearest star that we can see and it is almost the same size and age as the Sun.
What star that is very similar to sun?
Alpha Centauri is the nearest star that we can see and it is almost the same size and age as the Sun.
What is the distance from earth to alpha centaurs?
Alpha Centauri (Rigil Kentaurus, Rigil Kent, or Toliman) is the brightest star in the southern constellation of Centaurus.It is actually a binary star, but appears to us as a single star.Alpha Centauri A has an apparent magnitude of -0.01Alpha Centauri B has an apparent magnitude of +1.33
How do the mass and size of an alpha particle compare with mass and size of beta particle?
The mass and size of an alpha particle compare with the masa and size of beta particle in the sense that the alpha particle is significantly larger in both size and mass that the beta and gamma particles. This is why it is called the alpha particle.
How much larger the sun than polaris?
Polaris is actually a system of three stars, all of them larger than the sun. They range in size from 1.26 to 5.4 times the diameter of the sun. Polaris only appears smaller than the sun because it is several million times farther away.
How far away is the next nearest star?
Technically speaking the closest star to Earth is the sun which is about 93 000 000 miles (150 million kilometers) away. After that the next nearest star is Alpha Centauri and it is 4.37 light years away from our sun.
How old is Alpha Centauri compared to the Sun?
The Heliopause is at a distance of appx 120 AU from the Sun. That is around 0.0019 light years. Te Alpha Centauri star system is 4.365 light years away from the Sun, and almost the same distance away from the Heliopause.
Which is larger in size polaris or pollux?
Its apparent magnitude is about 2, but it's slightly variable. Usually it's given as 1.97v (where v means variable).
