How much larger is Betelgeuse than the Sun?

Betelgeuse, a red supergiant star roughly 950 times as large as the Sun, is one of the largest stars known. For comparison, the diameter of Mars’s orbit around the Sun is 328 times the Sun’s diameter.

How small is the Sun compared to Betelgeuse?

Betelgeuse is one of the largest known stars and is probably at least the size of the orbits of Mars or Jupiter around the sun. That’s a diameter about 700 times the size of the Sun or 600 million miles.

How many suns could fit in Betelgeuse?

This image, made with the Atacama Large Millimeter/submillimeter Array (ALMA), shows the red supergiant Betelgeuse — one of the largest stars known. In the millimeter continuum the star is around 1400 times larger than our Sun.

Is Betelgeuse bigger than our solar system?

Supergiant stars are the largest stars, and they are much larger than our own Sun. Betelgeuse, which happens to be the 9th brightest star in the sky, is much larger than our Sun. The radius of this star is up to 1200 times than of our sun. That means if Betelgeuse was placed where our sun is now, it would eat Jupiter.

What is Betelgeuse and why will it explode?

Betelgeuse is a red supergiant star in the constellation Orion. It left the main sequence about 1 million years ago, and has been a red supergiant for about 40,000 years. It’s a core-collapse SN II progenitor, which means that eventually, Betelgeuse will burn enough of its hydrogen that its core will collapse and it will explode as a supernova.

What is the luminosity of Betelgeuse?

Betelgeuse has about 140,000 times the luminosity of our sun or about 5.37×1031 watts.

How does the Sun compare with Betelgeuse?

Betelgeuse is 126,000 times more luminous than our Sun. It is also more massive, having 16.5 solar masses and a whooping 764 solar radii. This means that Betelgeuse is more than 1200 times bigger than our Sun. Big stars don’t necessarily mean hot stars, and Betelgeuse has a surface average temperature of only 3,600 K.

What is the classification of Betelgeuse?

Betelgeuse belongs to the spectral class M2Iab. The M refers to the star’s colour, red, and the ‘ Iab ’ suffix indicates that the star is an intermediate luminosity supergiant.
