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.
A galaxy is larger than Betelgeuse. Galaxies are massive cosmic structures containing billions to trillions of stars, while Betelgeuse is a single star, albeit a giant red supergiant star located in the constellation of Orion.
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
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.
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);

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.
Betelgeuse because it is a Red Supergiant.

Is Betelgeuse a dwarf planet?
No, Betelgeuse is not a dwarf planet. Betelgeuse is a supergiant star located in the constellation of Orion. It is one of the largest and most luminous stars known in our galaxy.
Is the sun larger than Betelgeuse?
No. Betelgeuse has 950-1200 times the diameter of the Sun.
Why is Jupiter in the night sky brighter than betelgeuse?
Jupiter appears brighter in the night sky than Betelgeuse because it is closer to Earth and reflects more sunlight due to its atmosphere. Betelgeuse, on the other hand, is a red supergiant star that emits its own light, which can make it appear dimmer in comparison.
How does the Sun compare with Betelgeuse?
The Sun is a relatively small, stable star that is in the main sequence stage of its life, while Betelgeuse is a massive, red supergiant star that is near the end of its life cycle. Betelgeuse is significantly larger and brighter than the Sun, despite being located much farther away in space.
How many earths in Betelgeuse?
The size of Betelgeuse is variable (it pulsates); plus, there are different estimates. But its diameter is approximately 900 times that of our Sun, which in turn is roughly 100 times the diameter of Earth (actually 109, but the data don't justify a very exact calculation), so Betelgeuse has roughly 900 x 100 = 90,000 times the DIAMETER of Earth; the ratio of volumes is that same number, cubed, or (after some rounding) about 700,000,000,000,000 times as much.
Which galaxy is the star Betelgeuse in?
Like all stars you can see at night, Betelgeuse is in our galaxy, the Milky Way.
What galaxy does betelegeuse belongs to?
Betelgeuse is in our own galaxy, the Milky Way.
Is sun one of the largest stars in the galaxy?
The Sun is an average-sized star compared to others in the galaxy. There are larger stars, known as supergiants, such as Betelgeuse and Antares that are much larger and more massive than the Sun.
Does Betelgeuse move?
Yes, all stars move. Betelgeuse is orbiting around the center of our galaxy.
Which is larger Rigel or Betelgeuse?
Betelgeuse is larger than Rigel. Betelgeuse is a red supergiant star with a diameter about 1,180 times that of the Sun, while Rigel is a blue supergiant with a diameter roughly 79 times that of the Sun.
How long does it take for betelgeuse to orbit its galaxy?
Since Betelgeuse is a nearby star (compared to the size of the galaxy, that is), you can assume that it takes about the same time as our Solar System to orbit the galaxy - approximately 240 million years.
Is Betelgeuse a dwarf planet?
No, Betelgeuse is not a dwarf planet. Betelgeuse is a supergiant star located in the constellation of Orion. It is one of the largest and most luminous stars known in our galaxy.
Is the sun larger than Betelgeuse?
No. Betelgeuse has 950-1200 times the diameter of the Sun.
What kind of galaxy is Betelgeuse in?
Our own galaxy, the Milky Way. In general, most stars that have a proper name (as opposed to just a catalog number), and definitely all stars you can see with the naked eye (except for an occasional supernova) are part of our own galaxy.
What are 5 stars in our galaxy?
Sirius, polaris, cygnus, betelgeuse, & rigel
How many miles is Betelgeuse larger than the sun?
Betelgeuse is approximately 900 times larger in diameter than the sun, about 1.5 billion kilometers.
Is Betelgeuse in the Milky Way galaxy?
Yes it is, as all stars that you can see with the naked eye are in the Milky Way galaxy.
