Is there a star bigger than quasi star?

It may seem massive, but that’s really nothing. Just 5.2 light-years away from us, there’s another star known as UY Scuti, which is 1,700 times larger than our Sun. Pretty big, right? But this quasi-star is even bigger than that.

Is Mu Cephei a red giant?

Mu Cephei (μ Cep) is a red supergiant located in the constellation Cepheus. With an average apparent magnitude of 4.08, it is the 10th brightest star in the constellation.

Who discovered Mu Cephei?

Johann Bayer first noted this star with its Greek letter designation of Mu Cephei in the 1600’s, although its variable nature was not recorded until 1848 by John Russell Hind.

Is VV Cephei A hypergiant?

Although VV Cephei A is an extremely large star showing high mass loss and having some emissions lines, it is not generally considered to be a hypergiant. The emission lines are produced from the accretion disc around the hot secondary and the absolute magnitude is typical for a red supergiant.

What color is VV Cephei?

Based on the spectral type (M2 comp) of the star, the VV Cephei colour is red . The star can be seen with the naked eye, that is, you don’t need a telescope/binoculars to see it. VV Cephei is a Binary or Multiple star system.

Is there a bigger star than Stephenson?

From Simple English Wikipedia, the free encyclopedia Size comparison of stars. A quasi-star compared to many large stars (UY Scuti is not the largest star, and even Stephenson 2-18 is actually smaller than a Quasi Star but Quasi stars are hypothetical, so they are just ideas, and likely not existent).

Will Stephenson 2-18 go supernova?

Also catalogued as Stephenson 2-DFK 1 and RSGC2-18, it is the current record holder for the largest star known, with a size 2,150 times that of the Sun. The star is located at a distance of 18,900 light years from Earth….Stephenson 2-18.

Who discovered the variable star Mu Cephei?

In 1848, English astronomer John Russell Hind discovered that Mu Cephei was variable. This variability was quickly confirmed by German astronomer Friedrich Wilhelm Argelander. Almost continual records of the star’s variability have been maintained since 1881.

What does Mu Cephei stand for?

Mu Cephei ( Latinized from μ Cephei, abbreviated Mu Cep or μ Cep ), also known as Herschel’s Garnet Star, Erakis, or HD 206936, is a red supergiant or hypergiant star in the constellation Cepheus. It appears garnet red and is located at the edge of the IC 1396 nebula.
