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.
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 the largest known star?
The largest known star in the universe, UY Scuti is a variable hypergiant with a radius around 1,700 times larger than the radius of the sun. To put that in perspective, the volume of almost 5 billion suns could fit inside a sphere the size of UY Scuti.
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.

How big is the universe?
While the spatial size of the entire universe is unknown, it is possible to measure the size of the observable universe, which is approximately 93 billion light-years in diameter at the present day.
What is the closest black hole to Earth?
Located just under 1,600 light-years away, the discovery suggests there might be a sizable population of dormant black holes in binary systems. The black hole Gaia BH1, seen in this artist’s concept near its Sun-like companion star, is the closest black hole to Earth discovered so far.
What is the heaviest black hole?
The most massive observed black hole is TON 618, which has an estimated mass of 66 billion times the mass of the sun and is located 10.8 billion light years from Earth.
Is black hole bigger than galaxy?
And while those black holes truly are massive — weighing millions, or even billions, of solar masses — they are tiny compared with their home galaxies, reaching less than 1% of the mass of a typical galaxy and a volume a billion times smaller.
