Is the Sun a supergiant?

Is the Sun a supergiant?

The Sun is medium-sized. The red supergiant Antares is 800 times wider than the Sun. If it was at the centre of our Solar System, it would swallow up all of the inner planets, including Earth. Like gas guzzler cars, these supergiants use all of their hydrogen and helium fuel very quickly.

What star is considered a supergiant?

A star classed as a supergiant may have a diameter several hundred times that of the Sun and a luminosity nearly 1,000,000 times as great. Supergiants are tenuous stars, and their lifetimes are probably only a few million years, extremely short on the scale of stellar evolution.

What is an example of a supergiant?

These are stars with many times the mass of the Sun, and one of the best known examples is Betelgeuse, in the constellation of Orion. The Betelgeuse star has 20 times the mass of the Sun, and puts out about 135,000 times as much energy as the Sun.

Is the Sun a blue supergiant?

The most massive stars in the Universe are the blue supergiant stars; then can have more than 20 times the mass of the Sun. Blue giant stars are very hot, with surface temperatures of 20,000-50,000 Kelvin. Just for comparison, our own Sun is only 6,000 Kelvin.

Which star is the hottest supergiant?

Blue supergiants
Blue supergiants are the hottest stars in the universe, having temperatures of around 10,000 K to 50,000 K or more. Blue supergiants are also quite bright, being between 10,000 to 1 million times brighter than our Sun.

What is the biggest supergiant star?

VY Canis Majoris
The largest known red supergiant is thought to be VY Canis Majoris, measuring about 1800 times the size of the Sun. Imagine if the Sun extended out to the orbit of Saturn. Let’s take a look at where red supergiant stars come from. Red supergiants are similar to red giants.

Which star is hottest supergiant?

Which star is hotter Mira or the sun?

Mira is hotter and bluer but intrinsically fainter than the Sun.

Why are blue supergiants so rare?

They are termed ‘blue supergiants’ due to their appearance and the enormous amounts of energy that they can radiate. They are rare – if you take a bunch of stars at random in our Galaxy, less than 0.1% of them will be blue supergiant stars.

What star is 100 times bigger than the sun?

Supergiant stars
Supergiant stars are the largest stars in the universe. They can be thousands of times bigger than our Sun and have a mass up to 100 times greater.
