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 ). [1] Galaxies are vast collections of stars, planets, nebulae and other objects that are surrounded by an interstellar medium and held together by gravity.
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.
Size A size comparison of the six largest galaxies of the Local Group, including the Milky Way. The Milky Way is one of the two largest galaxies in the Local Group (the other being the Andromeda Galaxy), although the size for its galactic disc and how much it defines the isophotal diameter is not well understood.

IC 1101 is a class S0 supergiant ( cD) lenticular galaxy at the center of the Abell 2029 galaxy cluster. It has an isophotal diameter at about 123.65 to 169.61 kiloparsecs (400,000 to 550,000 light-years). It possesses a diffuse core which is the largest known core of any galaxy to date, [5] and contains a supermassive black hole, one of the ...
Located in the Triangulum Galaxy: N44: 1,000 ly (310 pc) Emission nebula: Contains a 250 light year wide superbubble that was probably formed from stellar winds. N11: 1,000 ly (310 pc) H II region: N11 is the second largest star formation region in the Large Magellanic Cloud galaxy. NGC 2404: 940 ly (290 pc) H II region
The sizes are listed in units of Jupiter radii (71,492 km). All planets listed are larger than 1.7 times the size of the largest planet in the Solar System, Jupiter. Some planets that are smaller than 1.7 R J have been included for the sake of comparison.
Segue 2. 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).
