Astronomical objects discovered in 1881

NGC 38 (also known by the designations MCG-1-1-47 or PGC 818) is a spiral galaxy in the constellation Pisces. It was discovered on 30 September 1867 by Édouard Stephan.

NGC 4307 is an edge-on spiral galaxy located about 65 million light-years away in the constellation Virgo. It was discovered by astronomer Christian Peters in 1881 and is a member of the Virgo Cluster. It is also a LINER galaxy.

NGC 449 is a spiral galaxy of type (R')S? located in the constellation Pisces. It was discovered on November 11, 1881 by Édouard Stephan. It was described by Dreyer as "very faint, very small, round, very little brighter middle, very faint star involved."

NGC 354 is a barred spiral galaxy in the constellation Pisces. It was discovered on October 24, 1881 by Édouard Stephan. It was described by Dreyer as "very faint, very small, round, very small (faint) star involved, 14th magnitude star close to west."

NGC 341 is a spiral galaxy in the constellation Cetus. It was discovered on October 21, 1881 by Édouard Stephan. It was described by Dreyer as "faint, pretty large, round, a little brighter middle, mottled but not resolved." It has a companion galaxy, PGC 3627, which is sometimes called NGC 341B. For this, reason, it has been included in Halton Arp's Atlas of Peculiar Galaxies.

NGC 11 is a spiral galaxy located in the Andromeda constellation. It is located at right ascension 00 08 42.5; declination +37° 26′ 53″ under J2000.0 coordinates and was discovered by Édouard Stephan on October 24, 1881.

NGC 6051 is a giant elliptical galaxy located in the constellation of Serpens. The galaxy lies 453 million light-years from Earth, which means given its apparent dimensions, the galaxy is around 250,000 light-years across. It is the brightest cluster galaxy inside a relaxed poor cluster called AWM 4, a fossil system, making up of at least 30 galaxy members.

NGC 4611 is a intermediate spiral galaxy in the constellation of Coma Berenices. Its velocity with respect to the cosmic microwave background is 6,437 ± 22 km/s, which corresponds to a Hubble distance of 94.9 ± 6.7 Mpc (~310 million light-years). It was discovered by French astronomer Édouard Stephan on 17 May 1881. This galaxy was also observed by the American astronomer Lewis Swift on 20 April 1889, and listed in the Index Catalogue as IC 805.

NGC 605 is a lenticular galaxy in the constellation Andromeda, which is about 234 million light-years from the Milky Way. It was discovered on October 21, 1881 by the French astronomer Édouard Jean-Marie Stephan.

220 Stephania is a dark background asteroid from the inner regions of the asteroid belt, approximately 32 km (20 mi) in diameter. It was discovered on 19 May 1881, by Austrian astronomer Johann Palisa at the Vienna Observatory. The C-type asteroid has a rotation period of 18.2 hours. It was named after Princess Stéphanie of Belgium.
