While there are stars that are brighter and denser than UY Scuti, it has the largest overall size of any star currently known, with a radius of 1,708 ± 192 R☉. It's a crazy-bright candle, too, with a luminosity 340,000 times greater than the Sun. UY Scuti was first cataloged in 1860, by German astronomers at the Bonn Observatory, during the first sky An illustration of the approximate size of UY Scuti compared to the Sun. UY Sct is a UY Scuti's mass is uncertain, primarily because it has no visible companion star by which its mass can be.. If you're struggling to put UY Scuti's size into context, try this.

UY Scuti's Size. If our Sun were replaced by UY Scuti, the circumstellar habitable zone for an Earth-like planet would start at approximately 605 AU conservatively, and extends to 1183 AU. It has an absolute magnitude of -6.2, UY Scuti is thus 340.000 times more luminous than our Sun.

If the Earth was 20cm, the Sun would be 22 meters across and UY Scuti would be 40 km. For example, UY Scuti is currently at the top of the list. Uy Scuti Size Scale And Facts UY Scuti (BD-12 5055) is a red supergiant in the constellation Scutum. December 16, 2013 araho. Is this star really only 1/500,000,000 as dense as our sun? Largest known star UY Scuti is 5 billion times the size of the Sun. Size comparison. UY Scuti is the largest known star, with a diameter 1,708 times greater than the Sun. A quasi-star compared to many large stars (UY Scuti is smaller than VY Canis Majoris). The picture used is a modified picture of the Sun. There are currently no telescopes able to provide an image bigger than a small dot. UY Scuti changes its brightness but it can be viewed from Earth as it is a pulsating star. UY Scuti is a red supergiant star in the Scutum constellation. Below is a list of the largest stars so far discovered, ordered by radius. The picture was captured in 2011. As it stands, the title of the largest star in the Universe (that we know of) comes down to two contenders. Image: Wikipedia, by the user Haktarfone UY Scuti is the brightest star in the image. While there are stars that are brighter and denser than UY Scuti, it has the largest overall size of any star currently known, with a radius of 1,708 ± 192 R☉. The first is the star Sirius A, also called Alpha Canis Majoris A, the Dog Star. The unit of measurement used is the radius of the Sun (696,392 km; 432,717.927 mi). 1708 times as wide as our sun. It is one of the largest known stars by radius at 1,708 ± 192 solar radii, corresponding to the diameter of 2,375,828,000 kilometers. UY Scuti is a red supergiant star in the Scutum constellation. UY Scuti is located in or galaxy the Milky Way, at about 5.219 light-years away from Earth. In terms of sheer physical size, the star UY Scuti is considered the biggest known. It’s only 30 times the sun’s mass, but has a radius more than 1,700 greater than the sun. While there are stars that are brighter and denser than UY Scuti, it has the largest overall size of any star currently known, with a radius of 1,708 ± 192 R☉. An accurate comparison showing the red supergiants UY Scuti and VY Canis Majoris, image: Wikimedia Commons/Faren29 (CC … UY Scuti is only around 30 times more massive than the sun, but has a radius somewhere in the region of 1,700 times larger than the radius of the sun. 5,000,000,000 times the volume of our sun.
