Question: Which constellation is the star NGC 390 located in?
Context: NGC 388 is an elliptical galaxy located in the constellation Pisces.  It was discovered on November 4, 1850 by Bindon Stoney.  It was described by Dreyer as "very faint, small, round."  Along with galaxies NGC 375, NGC 379, NGC 382, NGC 383, NGC 384, NGC 385, NGC 386 and NGC 387, NGC 388 forms a galaxy cluster called Arp 331. 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 3626, also Caldwell 40, is a medium-tightness spiral galaxy and Caldwell object in the constellation Leo.  It was discovered by William Herschel, on 14 March 1784.  It shines at magnitude +10.6/+10.9.  Its celestial coordinates are RA 11 20.1 , dec +18 ° 21′ .  It is located near the naked-eye class A4 star Zosma, as well as galaxies NGC 3608, NGC 3607, NGC 3659, NGC 3686, NGC 3684, NGC 3691, NGC 3681, and NGC 3655.  Its dimensions are 2′.7 × 1′.9.  The galaxy belongs to the NGC 3607 group some 70 million light-years distant, itself one of the many Leo II groups. Pisces is a constellation of the zodiac.  Its name is the Latin plural for fish.  It lies between Aquarius to the west and Aries to the east.  The ecliptic and the celestial equator intersect within this constellation and in Virgo.  Its symbol is (Unicode ♓). NGC 387 is an elliptical galaxy located in the constellation Pisces.  It was discovered on December 10, 1873 by Lawrence Parsons.  It was described by Dreyer as "very faint, small, round."  Along with galaxies NGC 375, NGC 379, NGC 382, NGC 383, NGC 384, NGC 385, NGC 386 and NGC 388, NGC 387 forms a galaxy cluster called Arp 331. NGC 384 is an elliptical galaxy located in the constellation Pisces.  It was discovered on November 4, 1850 by Bindon Stoney.  It was described by Dreyer as "pretty faint, pretty small, southwestern of 2." , the other being NGC 385.  Along with galaxies NGC 375, NGC 379, NGC 382, NGC 383, NGC 385, NGC 386, NGC 387 and NGC 388, NGC 384 forms a galaxy cluster called Arp 331. NGC 385 is a lenticular galaxy located in the constellation Pisces.  It was discovered on November 4, 1850 by Bindon Stoney.  It was described by Dreyer as "pretty faint, pretty small, round, northeastern of 2." , the other being NGC 384.  Along with galaxies NGC 375, NGC 379, NGC 382, NGC 383, NGC 384, NGC 386, NGC 387 and NGC 388, NGC 385 forms a galaxy cluster called Arp 331. NGC 380 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, suddenly brighter middle."  Along with galaxies NGC 375, NGC 379, NGC 382, NGC 383, NGC 384, NGC 385, NGC 386, NGC 387 and NGC 388, NGC 380 forms a galaxy cluster called Arp 331. 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 2423-3b 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.
