What is the most massive star called?

R136a1. The star R136a1 currently holds the record as the most massive star known to exist in the universe. It’s more than 265 times the mass of our Sun, more than double most stars on this list.

What is a massive star example?

Perhaps the most familiar, extremely massive star is Eta Carinae, located about 8,000 light years from Earth. Astronomers think it has an estimated mass of between 100 and 150 solar masses. The star is probably less than 3 million years old, and it’s believed that it has less than 100,000 years left to live.

What is the heaviest star?

R136a1
R136a1 is the heaviest star, with 265 times the sun’s mass. It’s also the most luminous star known at more than 7 million times the luminosity of our sun. For decades, theories have suggested that no stars can be born by ordinary processes above 150 solar masses.

Is there a bigger star than the Sun?

There are bigger stars, and there are smaller stars. We have found stars that are 100 times bigger in diameter than our sun. Truly, those stars are enormous. We have also seen stars that are just one tenth the size of our sun.

Is Sirius a star?

Sirius, also called Alpha Canis Majoris or the Dog Star, brightest star in the night sky, with apparent visual magnitude −1.46. It is a binary star in the constellation Canis Major. The bright component of the binary is a blue-white star 25.4 times as luminous as the Sun.

What is massive star?

A massive star is a star that is larger than eight solar masses during its regular main sequence lifetime. Massive stars are born, just like average stars, out of clouds of dust called nebulae.

Is Moon a star?

In reality, the moon is not considered a star. While it shines just like many of the stars in the sky, its light comes from the sun, not itself. To be a star, a celestial body must be capable of igniting itself because of its mass. The moon’s core has never ignited, so it does not fall under the definition of a star.
