Why is the density of Betelgeuse so low?
Because it is so large. Density is a function of mass/volume.
What is the size of the betelgeuse?
Betelgeuse boasts the diameter greater than the orbit of Jupiter. It has a mass of around 20 times the mass of the Sun, and its luminosity is almost 200,000 times greater than the Sun. So really, it is one of the biggest and brightest stars ever observed.
What star is bigger betelgeuse or aldebaran?
betelgeuse
What are facts about Betelgeuse?
Betelgeuse is the eighth brightest star in the night sky and the second brightest star in the constellation of Orin. It is classified as a Red Giant. Astronomers believe that Betelgeuse is only 10 million years old, but has evolved rapidly due to its high mass. Betelgeuse is made from: Helium, Carbon, and Oxygen. Astronomers don't know when but they are sure that Betelgeuse will explode and become a SuperNova. Betelgeuse is 700 million miles in diameter and the surface temperature is 6,000 degrees Fahrenheit. Its luminosity is about 10,000 times the Sun and it's the first star to be directly imaged by a telescope. Finally Betelgeuse is visible in winter skies from the Northern Hemisphere in the constellation Orion. Hope that Helped You :)
Is Betelgeuse a binary star?
No. Betelgeuse is a single star.
Why is the density of Betelgeuse so low?
Because it is so large. Density is a function of mass/volume.
How small would Betelgeuse have to get to have its escape velocity equal the speed of light?
To calculate the required size, we can use the equation for escape velocity, v = sqrt((2GM)/r), where G is the gravitational constant, M is the mass of Betelgeuse, and r is its radius. Setting the escape velocity equal to the speed of light (c), we would need the radius to be smaller than the Schwarzschild radius (2GM/c^2). For Betelgeuse, this would require the radius to be smaller than about 3 kilometers (1.9 miles).
What is the name of the red giant that makes up the constellation Orion?
Betelgeuse is the name of the red super giant that makes up the constellation Orion. It is estimated that the mass of Betelgeuse is thirty times that of the sun.
What is the size of the betelgeuse?
Betelgeuse boasts the diameter greater than the orbit of Jupiter. It has a mass of around 20 times the mass of the Sun, and its luminosity is almost 200,000 times greater than the Sun. So really, it is one of the biggest and brightest stars ever observed.
Is betelgeuse the biggest star you know of?
No. The biggest star ever discovered is the VY Canis Majoris, a red hypergiant with a radius of easily 2000 times bigger than that of the Sun. That is more than twice the radius of Betelgeuse. Also, the mass of VY Canis Majoris is around twice that of Betelgeuse.

''Is Orion a low mass star''?
Orion is a constellation, not a star. Betelgeuse, the red giant at the left shoulder of Orion, is a supergiant.
