Betelgeuse, a red supergiant star in the constellation Orion, has an approximate radius of about 1,000 times that of the Sun. This translates to roughly 1.4 billion kilometers (about 870 million miles). However, due to its irregular shape and variations in size, estimates can vary slightly.
What else can I help you with?
What planet is bigger then Betelgeuse?
No planet could ever come close to the size of Betelgeuse.
What is the circumference of Betelgeuse?
Betelgeuse is a red supergiant star, and as such, it does not have a defined circumference like a solid object. Its size is measured in terms of solar radii, with Betelgeuse being approximately 1,000 times larger than the Sun.
Is Betelgeuse a pulsating star?
Yes: Betelgeuse is a semiregular variable star so it is classed as a pulsating star.
How did Betelgeuse get so big?
Betelgeuse is very big because is formed as a large star, and later it expanded even more as it ages, this creates its current size.
How are Sirius and betelgeuse unlike?
Sirius and Betelgeuse are both bright stars in the night sky, but they differ in size, color, and temperature. Sirius is a white star, while Betelgeuse is a red supergiant. Betelgeuse is also much larger and cooler than Sirius.

How big is Betelgeuse compared to Rigel?
Betelgeuse is larger in size than Rigel. Betelgeuse is a red supergiant star with a diameter about 800 times that of the Sun, while Rigel is a blue supergiant star with a diameter about 70 times that of the Sun.
What is the density of Betelgeuse?
Betelgeuse has a density of about 1.119 × 10−8 that of our Sun. See related question
How is the sun compared to the star betelgeuse?
The Sun and Betelgeuse are both stars, but they differ significantly in size and characteristics. Betelgeuse is a red supergiant star located in the constellation of Orion, while the Sun is a yellow dwarf star at the center of our solar system. Betelgeuse is much larger and more luminous than the Sun, with a diameter around 1,000 times that of the Sun. Additionally, Betelgeuse is much closer to the end of its life cycle compared to the Sun.
Is Betelgeuse bigger than Antares?
No, Antares is bigger than Betelgeuse. Antares is a red supergiant star with a diameter about 700 times that of the Sun, while Betelgeuse is a red supergiant star with a diameter about 600 times that of the Sun.
What kind of star is Betelgeuse exactly?
The star called Betelgeuse is a red giant. It is about 700 times the size of the sun, and its temperature is lower than that of the sun's, at around 6,000 degrees Fahrenheit.
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.
Why is Betelgeuse brighter than Antares?
Betelgeuse is brighter than Antares primarily due to its size and proximity. As a red supergiant star, Betelgeuse has a larger radius and emits more light than Antares, which is a red supergiant as well but is farther away from Earth. Additionally, Betelgeuse's apparent magnitude is about 0.42, while Antares has an apparent magnitude of about 1.06, making Betelgeuse appear brighter in our night sky. The combination of Betelgeuse's intrinsic luminosity and its relative closeness contributes to its brighter appearance.
