That honor goes to R136a1, which weighs in at about 300 times the mass of the sun but only about 30 solar radii. . Today, she serves as Editor-in-Chief of this website. The main factor here being mass loss - the rate at which stars of ~45 or more Solar masses shed material is just too fast for them to expand to a significant degree after leaving the main sequence. This uncertainty is why I used possibly one of the largest stars in my description of UY Scuti. Either way, its fun to imagine what it would be like to have one of these stars relatively close to us in space say, the distance to the nearest star system, Alpha Centauri, only four light-years away. As it stands, the title of the largest star in the Universe (that we know of) comes down to two contenders. If you think Betelgeuse is large, it does not even compare to the largest star we have located. But there are more ways than one to measure stars' bigness. If muscles can only contract, how do we expand our Is a person exposed to radiation contagious? Which star is bigger VY Canis Majoris or UY Scuti? This close-up of the R136 cluster, taken with the Very Large Telescope at the infrared wavelength of 2.2 microns, reveals a clutch of supermassive stars that includes R136a1.

What is the difference between HSI and Hscei? This increase in produced radiation causes an expansion of the hull of the star, thus it becomes so large. The Sun's radius is 695,800km, therefore the star's radius is an estimated 20,039,040.km. While, as you said, R136a1 will probably expand a bit more as it moves into the luminous blue variable stage (it's currently a nitrogen- and hydrogen-enriched Wolf-Rayet star, which, at its mass, means that it's in the late stages of core hydrogen fusion), it still won't get overly large, and will begin to shrink and heat up again as it sheds more material and becomes a hydrogen-depleted Wolf-Rayet star. However, the star was better documented in 2012 with the help of greater technological equipment. In other words, this single star is so large that its outer surface would extend far beyond the orbit of the planet Jupiter (which lies about five times farther from the sun than Earth). The radius of VY CMa is very roughly 1,420 times that of the Sun ( R ), which is close to the modelled maximum, the Hayashi limit, a volume nearly 8 billion times that of the Sun.VY Canis Majoris. 2:0710:125 Stars That Could Be Larger Than UY Scuti YouTubeYouTubeStart of suggested clipEnd of suggested clipIt could be much much much larger in other words it could potentially.
