The Whirlpool Galaxy lies at a distance of 23 [2] to 31 million light-years from Earth. [18] Based on the 1991 measurement by the Third Reference Catalogue of Bright Galaxies using the D 25 isophote at the B-band, the Whirlpool Galaxy has a diameter of 23.58 kiloparsecs (76,900 light-years). [2] [5] Overall the galaxy is about 88% the size of ...
It is commonly referred to as the oldest known grand design spiral galaxy in the universe, [2] but it is more accurately the earliest such galaxy known to exist in the universe, with a lookback time (the difference between the age of the universe now and the age of the universe at the time light left the galaxy [3]) of 10.7 billion years [1] in ...

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. Together, the two galaxies are one of the most famous interacting galaxy pairs.
The galaxy lies about 70 million light years away from Earth, which means, given its apparent dimensions, that NGC 1253 is approximately 110,000 light years across. [1] It was discovered by William Herschel on September 20, 1784. [3] NGC 1253 is categorised as having a having a bar, however its spiral arms are similar to that of Whirlpool Galaxy.
