R136a1/Spectral type
What is bigger than R136a1?
Although R136a1 is the most massive known star, it is not the largest, since it only stretches about 30 times the radius of our sun. The largest known star is UY Scuti, a hypergiant with a radius somewhere around 1,700 times larger than the sun. Its mass, however, is only 30 times that of our nearest star.
How bright is R136a1?
12.23
R136a1/Magnitude
What happens when R136a1 goes supernova?
It has a diameter of about 30 million miles / 48 million kilometers – about 35 times bigger than our Sun. Estimates place R136a1 at around 1 million years old. It has a radius of about 15 million miles / 24 million kilometers.
Why is R136a1 blue?
R136a1 is the highest mass star known, but its high temperature results in a relatively modest radius of 35 solar radii, explaining its blue appearance (warm stars are yellow and cool stars are red).
How old is R136a1?
around 1 million years old
R136a1 is quite a young star, at around 1 million years old. This can be explained since its location in the Large Magellanic Cloud is an active star-forming location.
Is R136a1 a blue giant?
It’s only 30 times the sun’s mass, but has a radius more than 1,700 greater than the sun. Left to right: a red dwarf, the Sun, a blue dwarf, and R136a1. R136a1 is not the largest known star in terms of radius or volume, only in mass and luminosity.
Will R136a1 become a black hole?
Estimates place R136a1 at around 1 million years old. It has a radius of about 15 million miles / 24 million kilometers. Due to its nature, it will explode into a supernova before its core collapses and it will become a black hole.
What if R136a1 replaced the sun?
Astronomers say that if R136a1 replaced our sun, it would outshine the sun by as much as the sun currently outshines the full moon. They say that if it replaced our sun, its high mass would pull Earth into a much smaller orbit, reducing the length of the Earth’s year to three weeks.
What happens if UY Scuti supernova?
It seems at least imaginable that UY Scuti might lose enough mass to evolve, instead, more-or-less peacefully into first a red giant then a white dwarf. If UY Scuti did become a supernova, the star’s low mass as a supernova candidate indicates it would not be an outstanding explosion.
Is R136a1 bigger than UY Scuti?
In terms of sheer physical size, the star UY Scuti is considered the biggest known. R136a1 is not the largest known star in terms of radius or volume, only in mass and luminosity. Image via Wikipedia. R136a1 is the heaviest star, with 265 times the sun’s mass.
