Inside V838 Monocerotis ring, we can find view variable stars which resembles to the main star [5], There are three Red supergiants in the constellation that are visible to the naked eye. Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. On the following list, we are going to discover 10 largest star in the universe.

8.

A symmetry of light curve of RW Cep isremarked in relation to the light minimum of 1979.

[21][7], The temperature intermediate between the red supergiants and yellow hypergiants, and itself varying considerably, has led to it being variously considered as a red hypergiant[22] or yellow hypergiant. For species on earth, Sun is source of power. The star is one of the largest stars known with a radius nearly 1,600 greater than the Sun's. Kharchenko, N. V.; Scholz, R. -D.; Piskunov, A. E. Irregular and Semi-Regular Variable Stars, https://www.conservapedia.com/index.php?title=RW_Cephei&oldid=1660857. These stars is measured using standard one solar radius (Solar radii), which is 695,500km or 432,450 miles or 0.004652 Astronomical units (AU), According to Graham M. Harper, Alpha Orionis has diameter 950-1000 solar radii. It has estimated 25 solar mass and 1,420 times wider than the sun. The solar radius is around 1,570. This page was last modified on 22 June 2020, at 16:58. If you used the 1997 Parallax value, you would get an absolute magnitude of -3.18 If you used the 2007 Parallax value, you would get an absolute magnitude of -4.02.

The exact location is around 2,400 light years from our planet. The brightness is 2.8×105 than earth. Information regarding Metallicity and/or Mass is from the E.U. In 2007, Hipparcos data was revised with a new parallax of 0.81000 which put RW Cephei at a distance of 4026.71 light years or 1234.57 parsecs. The items in red are values that I've calculated so they could well be wrong. From Hubble observation, Betelgeuse is 180 thousand times brighter than our Sun. RW Cephei, at 1,535 solar radii.

Mass: 13.9 M ☉ Radius: 1,158 R ☉ Luminosity: 295,000 L ☉ Surface gravity (log g) 0.2 cgs: Temperature: 3,956 ± 129 (3,749 - 5,018) K: Age: 18.7 Myr: Other designations
