The largest star that we know of is called VY Canis Majoris it’s a long way from Earth between 3,900 and 5,000 light years. It is also a massive red supergiant and a variable star. While it's much larger than all the planets combined, it's not even medium-sized in comparison to other more massive stars. It can be even mor Even if we narrow down the definition to the "observable" universe — what we can see — estimating the number of stars within it requires knowing just how big the universe is. And it's not alone in dwarfing Earth's dominant star. The star owes its name to the shape of the Pistol Nebula, which it illuminates. Jan. 11, 1787: William Herschel discovers 2 moons of Uranus, WOH G64, measuring 1,504 to 1,730 solar radii. In addition to being far away, many stars of such extreme mass are surrounded by clouds of outflowing gas created by extremely powerful stellar winds; the surrounding gas interferes with the already difficult-to … EMAIL. Buzz60 Representing the constellation Sagittarius, this red supergiant is 1,460 times the radius of our Sun. It's a red supergiant in the constellation Cygnus. During a second detection, the astronomers realized it grows brighter and dimmer over a 740-day period, leading astronomers to classify it as a variable star. If it were put in the position of the Sun, it would extend out to the orbit of Saturn. The largest known supergiant star, VY Canis Majoris, is up to 2,100 times the size of the Sun (based on upper estimates). And it's not alone in dwarfing Earth's dominant star. 2. The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun. So even though Eta Carinae is the most luminous star we know of, it’s extremely hot – 25,000 Kelvin – and therefore only 250 solar radii big. The largest known supergiant star, VY Canis Majoris, is up to 2,100 times the size of the Sun (based on upper estimates). So which star would take UY Scuti's place if it weren't exactly 1,708 solar radii? The radius of UY Scuti is about 1,700 times larger than the sun's radius. With a known radius in excess of a thousand times that of our Sun, this massive star is somewhere between 950 and 1,200 solar radii (the unit of distance used by astronomers to express the size of stars equal to the current radius of the Sun) and is expected to go supernova any time. This is due in part to the fact that at roughly 640 light-years from Earth, Betelgeuse is very close compared to the other stars on this list. New measurements brought it down to size.

Unlike planets, stars have no distinct surface with which to form an "edge" for measurements, nor do astronomers have a convenient ruler to take such measurements. He was born John Christopher Depp II in Owensboro, … VV Cephei. But the Sun is just one of the many stars in the universe, and truth be told, it is not that much big when compared to other stars. Case in point, VY Canis Majoris is only 3,500 Kelvin, and a really big star would be even cooler. What is the Largest Star in the Universe?Among the many many stars in our universe, today we try to discover which be the largest of them. There are 3 measurements we can use to gauge in an attempt to crown the biggest star in the universe: Solar radii (a measurement based on the radius of our sun) Solar mass (a measurement based on the mass of our sun) Luminosity (a measure of power). The size of WOH G64 is estimated at 2.985 billion kilometers She is one of the largest stars known. "As far as an astrophysicist is concerned, this is the surface of the star, as this is the point at which photons can leave the star," Scudder said. The star lies near the center of the Milky Way, roughly 9,500 light-years away. Of course, all stellar sizes are estimates, based on measurements taken from far away. In 1860, German astronomers at the Bonn Observatory first cataloged UY Scuti, naming it BD -12 5055. Meet the Top 20 of the biggest stars of this, which is our Universe. Yes, most of them sound like taken from a Star Wars or Star Trek movie. Finally, a listing of stars by size must take into account that there may be larger specimens that simply haven't been studied or even detected as yet. Astronomers studying this star closely have identified it as being part of a larger group of stars called the Cepheus OB1 stellar association that contains many hot massive stars, but also a number of cooler supergiants such as this one.
