What is larger a galaxy or Betelgeuse?

Answer 1

A nebula ... Latin word for "cloud" ... is any object in the sky that appears hazy or cloudy to the eye. It may be a cloud of luminous gas, or a group of stars so far away that they are perceived as a haze rather than as individual points of light. In the extreme ... the largest objects with star density large enough that they might merge into an apparent haze are galaxies. Clusters of galaxies are so large and widespread that their existence was not even suspected 100 years ago, for the same reason that an ant on a tree doesn't suspect that this tree is part of a forest, and there are large open spaces between forests.

Answer 2

Betelgeuse is much bigger, in size than Rigel - about 12 times. but only just smaller in terms of mass.

• Betelgeuse has a radius of about 936 times that of our Sun
• Rigel has a radius of about 78 times that of our Sun

• Betelgeuse has a mass of 18 times that of our Sun
• Rigel has a mass of 17 times that of our Sun

Answer 3

The 9th brightest star of the night sky, the Betelgeuse is a red super giant. If it were placed in our solar system, it would have reached the asteroid belt, engulfing Mercury, Venus, Earth and mars.

Answer 4

Betelgeuse is a red supergiant in the order of 1000 solar radii, while Capell is a binary pair of giant stars in the order of 10 solar radii each. There are many stars between these two sizes (From largest to smallest);

Answer 5

Betelgeuse (Alpha Orionis) is approximately 1,000 times larger than our Sun, whereas Deneb (Alpha Cygni) is estimated to be only 200-300 times the size of our Sun.

Answer 6

Betelgeuse because it is a Red Supergiant.

Answer 7

There are many stars bigger than Betelgeuse, to many to mention here, but the biggest currently known is VY Canis Majoris [See related question}

Answer 8

Betelgeuse is the biggest (936 Solar radii vs. 800 Solar radii) and the most massive (20 Solar masses vs. 15.5 Solar masses)

Answer 9

It is around 1000 times the diameter of the Sun.

Answer 10

A supercluster.

A supercluster is made up of many clusters, and a cluster is made up of hundreds, if not thousands of galaxies.
