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 3625 K.
This was once the smallest known actively fusing star, when found in 2005, through 2013. It is the smallest eclipsing red dwarf, and smallest observationally measured diameter. [101] [102] [103] CoRoT-15b: 82,200 Brown dwarf [104] VB 10: 82,300 Red dwarf: It was the smallest known star from 1948 to 1981. [105] TRAPPIST-1: 82,925
A dwarf galaxy is a small galaxy composed of about 1000 up to several billion stars, as compared to the Milky Way's 200–400 billion stars. [1] The Large Magellanic Cloud , which closely orbits the Milky Way and contains over 30 billion stars, [ 2 ] is sometimes classified as a dwarf galaxy; others consider it a full-fledged galaxy.

Supergiant elliptical galaxies are some of the largest galaxies known. The Condor Galaxy is a colossal spiral galaxy disturbed by the smaller IC 4970 . It is the largest known spiral galaxy with the isophotal diameter of over 717,000 light-years (220 kiloparsecs ).
Size (left) and distance (right) of a few well-known galaxies put to scale. The following is a list of notable galaxies.. There are about 51 galaxies in the Local Group (see list of nearest galaxies for a complete list), on the order of 100,000 in the Local Supercluster, and an estimated 100 billion in all of the observable universe.
Segue 2 is a dwarf spheroidal galaxy situated in the constellation Aries and discovered in 2009 in the data obtained by Sloan Digital Sky Survey.The galaxy is located at the distance of about 35 kiloparsecs (35,000 parsecs; 110,000 light-years) from the Sun and moves towards the Sun at a speed of 40 kilometres per second (25 mi/s).
