NGC 6363 , also listed twice in the catalog as NGC 6138 , is a 13.5 mag bright elliptical galaxy of the Hubble type E2 in the constellation Hercules .
It was "discovered" twice by Édouard Stephan ; first on September 2, 1872 (listed as NGC 6138 ), due to an error in the determination of the reference star, the observation on July 24, 1879 under NGC 6363 led to the second entry in the catalog. Modern astronomy partially references this second observation and assigns the number NGC 6138 to the non-NGC object PGC 58070 .
