Hace 1 día · Below are lists of the largest stars currently known, ordered by radius and separated into categories by galaxy. The unit of measurement used is the radius of the Sun (approximately 695,700 km; 432,300 mi). The Sun, the orbit of Earth, Jupiter, and Neptune, compared to four stars.
Hace 2 días · Despite their high luminosity, many of them are nevertheless too distant to be observed with the naked eye. Stars that are at least sometimes visible to the unaided eye have their apparent magnitude (6.5 or brighter) highlighted in blue. The first list gives stars that are estimated to be 60 M ☉ or larger
Hace 5 días · The first star in the list, Godzilla — an LBV in the distant Sunburst galaxy — is probably the brightest star ever observed, although it is believed to be undergoing a temporary episode of increased luminosity that has lasted at least seven years, in a similar manner to the Great Eruption of Eta Carinae that was witnessed in the ...

3 de may. de 2024 · For instance, UY Scuti holds the record for the largest known star, with a radius roughly 1,700 times that of the Sun. This colossal size means it would span beyond the orbit of Jupiter if placed at the center of our Solar System.
14 de may. de 2024 · The biggest star in the universe is known as UY Scuti, a red supergiant located in the constellation of Scutum. With a radius over 1,700 times that of the Sun, UY Scuti is one of the largest known stars in the universe. It is estimated to be around 5 billion years old and has a mass around 30 times that of the Sun.
Hace 3 días · In a series of papers describing their findings, the teams revealed that IRAS 23077 is actually a young star surrounded by a massive protoplanetary debris disk, the largest ever observed. This...
