Out of that list, Alpha Centauri is the nearest star to Earth. But there is one
closer: Proxima Centauri is a tiny, dim red dwarf star; "near" Alpha Centauri
only by astronomical standards, it is still 3 light MONTHS away. But that's still
3 light months closer to the Sun.

Rigel aldebaran Sirius Antares KY cygni betelgeuse pollux arrange in ascending order?
In terms of size from smallest to largest, its Sirius, Pollux, Aldebaran, Rigel, Betelgeuse, Antares, and KY Cygni.
How many stars does antares have?
Antares (Alpha Scorpii) is a huge red hypergiant star, with a radius 800 times that of our own sun. There are some bigger stars though, such as Betelgeuse (1180 solar radii) and V354 Cephei (1520 solar radii), but the biggest known star is VY Canis Majoris, which is estimated to have a diameter between 1800 and 2100 times that of our own sun. If it were in the centre of our solar system its edges would almost reach the orbit of Saturn.
Is Betelgeuse a yellow star?
No, Betelgeuse is a red star.
Why is Jupiter in the night sky brighter than betelgeuse?
Jupiter is brighter than Betelgeuse in the night sky because it is much closer to the Earth in comparison to Betelgeuse(Betelgeuse is more than 500 lightyears away form the Earth). This way, Jupiter appears larger than Betelgeuse, and celestial objects that appear larger also appear brighter than objects that appear small.
Betelgeuse is the brightest star in the constellation Orion However Betelgeuse is a cool red star that is 520 light years from Earth How can Betelgeuse look so bright if it is that far away?
It isn't the brightest star - at least, usually Rigel is brighter. However, Betelgeuse is variable, and can sometimes be brighter than Rigel. Wikipedia lists its luminosity as 105,000 times the luminosity of our Sun; and the distance, as 640 light years. Assuming these numbers, this would make it as bright as a star that is 10.5 times as bright as our Sun, at a distance of only 6.4 light years. In other words, the extreme luminosity compensates for its distance.

Which is brighter Aldebaran or Betelgeuse?
This could be considered a trick question. Generally, Betelgeuse is brighter BUT Betelgeuse is what we call a variable star and there are times when it is fainter than Aldebaran.

Brightnest is a factor of luminousity and distance as seen from Earth. (Apparent magnitude)Vega - 0.03.Betelgeuse: 0.42So Betelgeuse is brighter as viewed from Earth.

Yes, Betelgeuse has a radius about 1200 times the size of the sun, and Antares is about 800 times the radius of the sun.
What star is brighter Betelgeuse or Rigel?
Betelgeuse has an apparent magnitude of 0.42(v) and an absolute magnitude of -6.02. Rigel has an apparent magnitude of 0.12 and an absolute magnitude of -7.04. So Rigel is brighter.
Which is brighter Rigel or Betelgeuse?
