Is R136a1 bigger than UY Scuti?
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.
Is Stephenson 2/18 bigger than Sagittarius A?
Stephenson 2-18 is a Red hypergiant Star that is in the constellation of Scutum within the Star cluster of Stephenson 2. It is 19,570 light-years away from the Earth, near the supermassive black hole named Sagittarius A*. It is the largest Star in the Galaxy.
Is there a star bigger than UY Scuti?
Other contenders. UY Scuti’s large radius does not make it the most massive, or heaviest, star. That honor goes to R136a1, which weighs in at about 300 times the mass of the sun but only about 30 solar radii. UY Scuti, in comparison, is only about 30 times the mass of the sun, but far greater in volume.
Which is the biggest thing in universe?
The biggest single entity that scientists have identified in the universe is a supercluster of galaxies called the Hercules-Corona Borealis Great Wall. It’s so wide that light takes about 10 billion years to move across the entire structure.
Which is the 2 largest star in the universe?
| Rank | Name | Dec |
|---|---|---|
| 1 | UY Scuti | -12.5° |
| 2 | V766 Centauri Aa | -62.6° |

What if R136a1 replaced our 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 would happen if R136a1 went supernova?
Due to its massive size and intense luminosity R136a1 will burn out its fuel very quickly. Given its nature, it will inevitably become either a black hole or a neutron star after suffering a type lc core-collapse supernova. But because of its enormous mass, the most likely outcome is that it will become a black hole.
What is the heaviest star?
The star R136a1 was initially measured at around 250 to 320 times the mass of our own Sun. The new estimate places it between 150 and 230 times the mass of the Sun.
Is TON 618 bigger than the Milky Way?
In the case of Ton 618, the enormous Lyman-alpha nebula surrounding it has the diameter of at least 100 kiloparsecs (320,000 light-years), twice the size of the Milky Way.
Is Phoenix a bigger than TON 618?
English: Phoenix A, the new largest known black hole, compared to famous ultramassive black hole Ton 618 and the Orbit of Neptune for scale.
How many suns can fit in TON 618?
That goes to the aptly named TON 618, a quasar (an active black hole consuming material and surrounded by streams of particles) that outshines the galaxy in which it sits. TON 618 is as bright as 140 trillion suns and has a mass of about 66 billion suns.
What is the biggest galaxy?
Earlier this year, astronomers found an absolute monster of a galaxy. Lurking some 3 billion light-years away, Alcyoneus is a giant radio galaxy reaching 5 megaparsecs into space. That’s 16.3 million light-years long, and it constitutes the largest known structure of galactic origin.
Does quasi-star exist?
A quasi-star (also called black hole star) is a hypothetical type of extremely massive and luminous star that may have existed early in the history of the Universe.
What is the hottest star in the universe?
The Wolf-Rayet star WR 102 is the hottest star known, at 210,000 K.
What is hottest thing in the universe?
A supernova is the hottest thing in the universe. The temperatures at the core during an explosion skyrocket up to 6000X the temperature of the sun’s core.
What’s bigger than a reality?
Perception is Bigger than REALITY.

What is bigger UY Scuti or 618?
Some would say the largest object in the universe is UY Scuti, the largest known star. It’s a red supergiant with a mass “only” 7–10 times the mass of the Sun, but with a radius up to 1,708 times the size! That’s only 0.3% the size of TON 618, but obviously still stupendously large.

What is the biggest star NASA?
Answer: The largest known star (in terms of mass and brightness) is called the Pistol Star. It is believed to be 100 times as massive as our Sun, and 10,000,000 times as bright! In 1990, a star named the Pistol Star was known to lie at the center of the Pistol Nebula in the Milky Way Galaxy.
