List of nearest galaxies. This is a list of known galaxies within 3.8 megaparsecs (12.4 million light-years) of the Solar System, in ascending order of heliocentric distance, or the distance to the Sun. This encompasses about 50 major Local Group galaxies, and some that are members of neighboring galaxy groups, the M81 Group and the Centaurus A ...
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.
A starchart of the night sky towards the Galactic Center. The Galactic Center is the barycenter of the Milky Way and a corresponding point on the rotational axis of the galaxy. [1] [2] Its central massive object is a supermassive black hole of about 4 million solar masses, which is called Sagittarius A*, [3] [4] [5] a compact radio source which ...
In the 4th century BC Greece, philosophers developed the geocentric model, based on astronomical observation; this model proposed that the center of the Universe lies at the center of a spherical, stationary Earth, around which the Sun, Moon, planets, and stars rotate. With the development of the heliocentric model by Nicolaus Copernicus in the ...
New York City [1] [16] Manhattan – often referred to as the Center of the Universe. Times Square [17] [18] Otter Creek, Maine – A bench with "Otter Creek, Maine – Capital of the World and Center of the Universe" across back seat of a bench in village. The slogan appears on patches, hats and printed material.
Observations indicate that there are SMBHs located near the center of most normal galaxies. [183] [184] The nature of the Milky Way's bar is actively debated, with estimates for its half-length and orientation spanning from 1 to 5 kpc (3,000–16,000 ly) and 10–50 degrees relative to the line of sight from Earth to the Galactic Center.
Cited distance is the orbital diameter of the Leo T Dwarf galaxy, the most distant galaxy in the Milky Way subgroup. Currently 59 satellite galaxies are part of the subgroup. Local Group: 3 Mpc: 9.26×10 19: 19.97: Group of at least 80 galaxies of which the Milky Way is a part.
In terms of shape, Europe is a collection of connected peninsulas and nearby islands. The two largest peninsulas are Europe itself and Scandinavia to the north, divided from each other by the Baltic Sea. Three smaller peninsulas— Iberia, Italy, and the Balkans —emerge from the southern margin of the mainland.
