NGC 2342 is an active spiral galaxy from the Hubble type Sc with extended star formation in the constellation of twins on the ecliptic . It is an estimated 233 million light years from the Milky Way and about 95,000 light years in diameter. Together with NGC 2341 , it forms the gravitationally bound galaxy pair KPG 125 or Holm 86 .
The object was discovered on November 10, 1864 by the astronomer Albert Marth using a 48 inch reflector telescope and is therefore listed in the New General Catalog .
