NGC 5195 (also known as Messier 51b or M51b) is a dwarf galaxy that is interacting with the Whirlpool Galaxy (also known as M51a or NGC 5194). Both galaxies are located approximately 25 million light-years away in the constellation Canes Venatici .
The M51 Group is a group of galaxies located in Canes Venatici.The group is named after the brightest galaxy in the group, the Whirlpool Galaxy (M51A). Other notable members include the companion galaxy to the Whirlpool Galaxy and the Sunflower Galaxy (M63).
The Whirlpool Galaxy, also known as Messier 51a (M51a) or NGC 5194, is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus. [ 6 ] [ 7 ] [ 8 ] It lies in the constellation Canes Venatici , and was the first galaxy to be classified as a spiral galaxy. [ 9 ]
Messier 53 (also known as M53 or NGC 5024) is a globular cluster in the Coma Berenices constellation. [a] It was discovered by Johann Elert Bode in 1775.M53 is one of the more outlying globular clusters, being about 60,000 light-years (18.4 kpc) light-years away from the Galactic Center, and almost the same distance (about 58,000 light-years (17.9 kpc)) from the Solar System.
Messier 81 (also known as NGC 3031 or Bode's Galaxy) is a grand design spiral galaxy about 12 million light-years away in the constellation Ursa Major. It has a D 25 isophotal diameter of 29.44 kiloparsecs (96,000 light-years ).

Messier 49 was the first member of the Virgo Cluster of galaxies to be discovered. [8] It is the most luminous member of that cluster and more luminous than any galaxy closer to the Earth. This galaxy forms part of the smaller Virgo B subcluster 4.5° away from the dynamic center of the Virgo Cluster, centered on Messier 87.
The Ring Nebula (also catalogued as Messier 57, M57 and NGC 6720) is a planetary nebula in the northern constellation of Lyra. [4] C] Such a nebula is formed when a star, during the last stages of its evolution before becoming a white dwarf , expels a vast luminous envelope of ionized gas into the surrounding interstellar space .
