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 ...
Charles Messier. The first edition of 1774 covered 45 objects (M1 to M45).The total list published by Messier in 1781 contained 103 objects, but the list was expanded through successive additions by other astronomers, motivated by notes in Messier's and Méchain's texts indicating that at least one of them knew of the additional objects.

The Shapley–Sawyer Concentration Class is a classification system on a scale of one to twelve using Roman numerals for globular clusters according to their concentration. . The most highly concentrated clusters such as M75 are classified as Class I, with successively diminishing concentrations ranging to Class XII, such as Palomar
The Andromeda Galaxy (Messier 31) hosts a SMBH about 10 times larger than our own, and has a σ ≈ 160 km/s. [3] Groups and clusters of galaxies have more disparate (contrasting in degree) velocity dispersions than smaller objects.
Charles Messier (French: [ʃaʁl me.sje]; 26 June 1730 – 12 April 1817) was a French astronomer. He published an astronomical catalogue consisting of 110 nebulae and star clusters , which came to be known as the Messier objects , referred to with the letter M and their number between 1 and 110.
HTML::WikiConverter – a Perl module to convert HTML to wiki markup language. Write the bash script "doc2mw", and the perl script "html2mw", both shown below. Call doc2mw passing the word document as parameter. i.e. > doc2mw my_word.doc doc2mw a bash script taking a single parameter, which calls wvHtml followed by html2mw.
