Messier 75 is part of the Gaia Sausage, the hypothesized remains of a dwarf galaxy that merged with the Milky Way. [10] It is a halo object with an orbital period of 0.4 billion years to travel around the galaxy on a very pronounced ellipse, specifically eccentricity of 0.87. The apocenter (maximal distance from Earth) is about 57,000 ly ...
Articles with the Messier number in the title use [[Category:Messier objects|###]], dropping the M prefix, and using only the number. The number should be padded up to 3 digits using zeroes.
