List of the largest known stars in Andromeda and Triangulum galaxies Star name Solar radii (Sun = 1) Galaxy Method [a] Notes Theoretical limit of star size (Andromeda Galaxy) ≳1,750 [9] L/T eff: Estimated by measuring the fraction of red supergiants at higher luminosities in a large sample of stars. Assumes an effective temperature of 3,625 K.
The Andromeda Galaxy is a barred spiral galaxy and is the nearest major galaxy to the Milky Way. It was originally named the Andromeda Nebula and is cataloged as Messier 31 , M31 , and NGC 224 . Andromeda has a D 25 isophotal diameter of about 46.56 kiloparsecs (152,000 light-years ) [ 8 ] and is approximately 765 kpc (2.5 million light-years ...
Andromeda: Largest galaxy in the group [12] Diameter (D 25 isophote): 152,000 light-years Mass: (1.5 ± 0.5) × 10 12 M ☉ Number of stars: ca. 10 12. Milky Way Galaxy: SBbc Sagittarius (centre) Second largest galaxy in the group, which may or may not be the most massive galaxy of the group. [13] Diameter (D 25 isophote): 87,400 light-years
The studies also suggest that M33, the Triangulum Galaxy—the third-largest and third-brightest galaxy of the Local Group—will participate in the collision event, too. Its most likely fate is to end up orbiting the merger remnant of the Milky Way and Andromeda galaxies and finally to merge with it in an even more distant future.
The Andromeda Galaxy with M110 at upper left and M32 to the right of the core. The Andromeda Galaxy (M31) has satellite galaxies just like the Milky Way.Orbiting M31 are at least 13 dwarf galaxies: the brightest and largest is M110, which can be seen with a basic telescope.
a variable star in the constellation of Andromeda. It is classified as a semiregular variable pulsating giant star, and varies from an apparent visual magnitude of 14.5 at minimum brightness to a magnitude of 9.9 at maximum brightness, with a period of approximately 238.3 days.
Most galaxies, including our Milky Way, contain tens of billions of stars that are readily observable. Even in nearby galaxies, such as Andromeda, which is about 2.5 million light-years away ...
Stars within the Milky Way are also visible, and are typically larger than stars within the Andromeda Galaxy. [ 12 ] [ 13 ] The final composite was stitched together using 411 exposures taken from July 2010 to October 2013, [ 14 ] and the image was first displayed at the 225th meeting of the American Astronomical Society in Seattle , Washington.
