Which constellation is the star NGC 390 located in?
Pisces
NGC 390
NGC 390 is a star located in the constellation Pisces.
 It was discovered on November 19, 1884 by Guillaume Bigourdan.
 It was described by Dreyer as very faint, very small, stellar."
 However, this position precesses to a position where there is nothing apart from a few scattered stars.
 However, Bigourdan's original measurements point exactly to a star, which is the most likely candidate for NGC 390; however, as a result of this confusion, a galaxy nearby (PGC 4021) has sometimes been mistaken as NGC 390.

NGC 375 is an elliptical galaxy located in the constellation Pisces.
 It was discovered on September 12, 1784 by William Herschel.
 It was described by Dreyer as "pretty faint, small, round, brighter middle."
 Along with galaxies NGC 379, NGC 380, NGC 382, NGC 383, NGC 384, NGC 385, NGC 386, NGC 387 and NGC 388, NGC 375 forms a galaxy cluster called Arp 331. NGC 2423-3 b
NGC 2423-3b is an extrasolar planet approximately 2498 light-years away in the constellation of Puppis.
 The planet was announced in 2007 to be orbiting the red giant star NGC 2423-3 (which in turn is part of the NGC 2423 open cluster).
 The planet has a mass at least 10.6 times that of Jupiter.
 Only the minimum mass is known since the orbital inclination is not known, so it may instead be a brown dwarf.
