[2] A preliminary version of the catalogue first appeared in 1774 in the Memoirs of the French Academy of Sciences for the year 1771. [3] [4] [5] The first version of Messier's catalogue contained 45 objects, which were not numbered. Eighteen of the objects were discovered by Messier; the rest had been previously observed by other astronomers. [6]
88 Aquarii is the Flamsteed designation, though it also bears the Bayer designation c 2 Aquarii. In dark conditions it is visible to the naked eye with an apparent visual magnitude of +3.68. [2] Based upon parallax measurements, this star is at a distance of around 271 light-years (83 parsecs) from Earth. [1]
NGC 5866 (also called the Spindle Galaxy or possibly Messier 102) is a lenticular galaxy in the constellation Draco.NGC 5866 was most likely discovered by Pierre Méchain or Charles Messier in 1781, and independently found by William Herschel in 1788.
74 Aquarii (abbreviated 74 Aqr) is a triple star [12] system in the constellation of Aquarius. 74 Aquarii is its Flamsteed designation and it also bears the variable star designation HI Aquarii . The combined apparent visual magnitude is 5.8, [ 5 ] although it is very slightly variable , [ 3 ] and it is located at a distance of 590 light-years ...
FO Aquarii is an intermediate polar [4] star system in the constellation Aquarius. The white dwarf and companion star orbit each other with a period of approximately 4.85 hours. [5] The system is famous for a very strong optical pulsation which occurs every 20.9 minutes, corresponding with the rotational period of the accreting white dwarf. [6]
