- 1 There are around 200 billion stars in the Milky Way alone.  VY Canis Majoris is the largest known star in our galaxy, if this star was in the center of our solar system its outer atmosphere would reach the orbit of Saturn.

What is the Biggest Star in the Universe? Follow the links below to learn more about these monster stars. R136a1 is the heaviest star, with 265 times the sun’s mass. UY Scuti is just plain big, with a radius 1,700 times that of our 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.his star is thought to have only 25 times the sun’s mass. List of largest known stars. So you can see that there are extremely heavy stars … and then there are simply gigantic stars. What makes a star big might be its mass (like R136a1) or its physical size (like UY Scuti and the two other stars mentioned here).

- Largest Planet: Jupiter. The largest planet in our solar system by far is Jupiter, which beats out all the other planets in both mass and volume. Jupiter’s mass is more than 300 times that of Earth, and its diameter, at 140,000 km, is about 11 times Earth’s diameter.

VY Canis Majoris Humphreys originally estimated the radius of VY CMa at 1,800-2,100 solar radii, which made it the largest star then known. A more recent and accurate VLTI measurement gives the star a radius of 1420 ± 120 solar radii.

The Largest Stars in the Universe That excess energy overflow from the nuclear fusion reaction within R136a1 means that more energy pours out from it into outer space in the form of heat and light than from any other known star. In other words, R136a1 is the most luminous star known. Secondly, what is the largest known star in outer space, in terms of volume? R Doradus: With a maximum variable magnitude of 4.8 this star should be discernible to the naked eye in the southern hemisphere, however infrared imaging reveals it to actually be an extremely bright star 6500 times more luminous than the one sustaining our Solar System.

StarChild Question of the Month for May 2000 UPDATE! As of January 2009, we now know about some other really big stars. One is called Eta Carinae. It has a size about 800 times that of our Sun, a mass about 100 times that of our Sun, and is about 4,000,000 times brighter than our Sun.

Top 10 Largest Stars In The Universe This red hypergiant star is by far the largest known. It has an estimated radius between 1800 and 2100 times the radius of our Sun. With this size it would reach nearly to the orbit of Saturn if placed in our solar system.The star is located roughly 4,900 light-years from Earth in the constellation Canis Majoris.he star that we are most familiar with is our Sun. However, compared to many of the other stars in the Universe our central stars is, well, kinda puny. Below is a list of the 10 largest (by diameter) stars known to exist in the Universe.

Alpha Centauri system, closest to sun The Alpha Centauri system is the closest star system to our sun. On our sky’s dome, we see this multiple system as a single star – the third-brightest star visible from Earth. Follow the links below to learn more about Alpha Centauri. The Alpha Centauri system probably consists of three stars.

What is the biggest star in our solar system? Correct - the sun is the only star in our solar system. Planet X is a kuiper belt object or dwarf planet officially named Eris (the name Xena had been proposed but was not selected) Eris is the largest known dwarf planet and is larger than Pluto.

- The Sun is in the center of the solar system. Our solar system is always in motion. Eight known planets and their moons, along with comets, asteroids, and other space objects orbit the Sun. The Sun is the biggest object in our solar system. It contains more than 99% of the solar system's mass.

What is the largest known star? But that’s nothing. The largest known star is VY Canis Majoris; a red hypergiant star in the Canis Major constellation, located about 5,000 light-years from Earth. University of Minnesota professor Roberta Humphreys recently calculated its upper size at more than 1,540 times the size of the Sun.

The Largest Star Known in the Universe -- A Red Supergiant in Death Throes The Largest Star Known in the Universe -- A Red Supergiant in Death Throes. When the astronomers studied the images of the most massive cluster of stars in our galaxy, Westerlund 1, they spotted something truly unique.louds of this type are rarely found around massive stars and are even rarer around red supergiant stars such as W26, the largest known star in the Universe — this is the first ionised nebula ever discovered around such a star.

UY Scuti UY Scuti was found to be the largest of the three stars measured, at 1,708 ± 192 R ☉ . This makes the star's radius the largest known of any star and approximately 1.7 times the size of the famous Betelgeuse.

- Of all known stars, the VY Canis Majoris is the largest. This red Hypergiant star, found in the constellation Canis Major, is estimated to have a radius at least 1,800 that of the Sun’s. In astronomy-speak we use the term 1,800 solar radii to refer to this particular size.Y Canis Majoris a.k.a. VY CMa is about 4,900 light years from the Earth. This value, however, is just a rough estimate because it is too far for parallax to be used.

- 1 VY Canis Majoris is the largest known star in our galaxy, if this star was in the center of our solar system its outer atmosphere would reach the orbit of Saturn.  One of the smallest known stars in our galaxy is VB 10, it is only around 20% larger than Jupiter.

How big is the biggest star we have ever found? Not surprisingly, UY Scuti is classified as a hypergiant star – which is the classification which comes after supergiant and regular giant. Its size may make it the biggest, but it is not the most massive star (where the mass in massive stands for the amount of matter in the star).

What Is The Largest Known Star In The Universe? So while solar radii would give us the “largest star in universe” by radius/circumference, it wouldn’t give us the most massive star (solar mass), or the most powerful star (luminosity). With that in mind, let’s take a look at some of the largest stars, most massive stars, and most powerful stars in the known universe.

What is the Biggest Star in the Universe? But that’s nothing. The largest known star is VY Canis Majoris; a red hypergiant star in the Canis Major constellation, located about 5,000 light-years from Earth. University of Minnesota professor Roberta Humphreys recently calculated its upper size at more than 1,540 times the size of the Sun.he noted that the largest stars are the coolest. So even though Eta Carinae is the most luminous star we know of, it’s extremely hot – 25,000 Kelvin – and so only a mere 250 solar radii. The largest stars will be the cool supergiants.

UY Scuti UY Scuti is a star that is within our galaxy, the Milky Way. It can be located in the constellation of scutum. UY Scuti is one of the largest Giant Stars in The Milky Way if not possibly the universe. It is not as some might think in our Solar System, it is the centre of its own Solar System. However as we are unable to measure all the stars, we will not know if that is the case that it is the largest in Universe.
