The estimated mass of UY Scuti is between 7 and 10 solar masses, and the star is losing mass at a rate of 5.8 x 10-UY Scuti was designated BD-12 5055 by a group of German astronomers at the Bonn Observatory, who were the first to catalogue the star in 1860, while conducting a survey for the The star’s true size was calculated after a survey with the Very Large Telescope (VLT) in the Atacama Desert in Chile, conducted in 2012 to measure the parameters of three large stars in the region of the sky near the Galactic Centre. When it does, the X-ray and gamma ray radiation will not affect Earth. UY Scuti was first catalogued in 1860 by German astronomers at the On detection in the second survey, the star was found to have changed slightly in brightness, suggesting that it was a new UY Scuti's mass is uncertain, primarily because it has no visible companion star by which its mass can be measured through gravitational interference.

For reference, R136a1 has an estimated radius of only about 30 solar radii. In spite of its enormous size – 7 to 8 astronomical units across – UY Scuti does not even make the list of the most massive stars known. In spite of its enormous size – 7 to 8 astronomical units across – UY Scuti does not even make the list of the most massive stars known. 5.12), and R Scuti (mag. As it is only 9th magnitude even at its brightest, UY Scuti is invisible to the naked eye. It is currently the largest known star by diameter, and has a mass of 10 M☉. However, it is expected to be between 7 and 10 After fusing heavy elements, its core will begin to produce iron, disrupting the balance of gravity and radiation in its core and resulting in a In terms of mass, UY Scuti also does not come close to the famous Eta Carinae A (between 100 and 200 solar masses), the central star of the Carina Nebula, or to the Peony Star (WR 102ka, 100 solar masses), which illuminates the Peony Nebula.The margin of error on the measurement of UY Scuti’s size is 192 solar radii, which means that there is a possibility that it may not be the largest known star after all. 8) open cluster Messier 26, the globular cluster NGC 6712 (mag 8.69), and the planetary nebula IC 1295 (mag. With an estimated mass between 7 and 10 solar masses, it is not even in the same ballpark as the current record holder R136a1 (315 solar masses), located in the Tarantula Nebula in the Large Magellanic Cloud. The star can be observed in a 4-inch or larger telescope in good conditions. 4.66), Gamma Scuti (mag. The star’s location in the galactic disc indicates that it is metal-rich and, once it runs out of helium, fusing heavy elements will result in the star’s core producing iron and disturbing the balance needed to sustain the core against its own gravity. 12.7).Scutum is also home to the famous variable star Delta Scuti, an F-type giant that serves as a prototype for its own class of variable stars.None of the stars in Scutum are among the 300 brightest stars in the sky. 6.5) is located in the same area of the sky.UY Scuti is located in the constellation Scutum, the Shield. The size of UY Scuti is about 750 million miles, or almost eight astronomical units.
There are generally two ways of finding planets. UY Scuti, in comparison, is only about 30 times more massive than the sun.

On detection in the second survey, the star was found to have changed slightly in brightness, suggesting that it was a new variable star. NASA's Hubble Space Telescope reveals the supercluster Westerlund … If the star were placed at the centre of our solar system, it would extend far beyond the orbit of Jupiter, closer to the orbit of Saturn.To illustrate, if the Earth were the size of a ball 20 cm (8 inches) in diameter, Jupiter would be 2.1 m (7 feet) in diameter, the Sun would be 22 m (7 feet) across, and the diameter of UY Scuti would extend for about 38,000 m (125,000 feet).

4.67), Delta Scuti (mag. HNsky has 4 different databases , stars down to 20 mag. Located some 9,500 light-years away, this star is the leading candidate for being the largest known star. 6.5) is located in the same area of the sky.UY Scuti is located in the constellation Scutum, the Shield. Given it is a red supergiant, termination comes within a very few million years. UY Scuti este o supergigantă roșie din constelația Scutul, situată la aproximativ 2,9 kpc, adică la 9.500 de ani-lumină de Terra.

It will eventually become a yellow hypergiant, a Wolf-Rayet star, or a luminous blue variable. The star can be observed in a 4-inch or larger telescope in good conditions. When it does, the X-ray and gamma ray radiation will not affect Earth.

The constellation was created in the 17th century and originally named Scutum Sobiescianum in honour of the Polish King John III Sobieski and his triumph in the 1683 Battle of Vienna.Scutum is one of the smallest constellations in the sky (84th in size out of 88), but contains several relatively bright deep sky objects that are popular targets for stargazers. The size of UY Scuti is about 750 million miles, or almost eight astronomical units.
