NGC 1135 is a spiral galaxy of Hubble type Scd in the constellation Horologium the southern sky . It is estimated to be 590 million light years from the Milky Way and about 125,000 light years in diameter.
In the same area of the sky is u. a. the galaxy NGC 1136 .
The object was discovered by John Herschel on September 11, 1836 . Although all the sources consulted identify PGC 10800 as NGC 1135 and PGC 10807 as NGC 1136, Professor Seligman points out that the description given by John Herschel for these two galaxies is identical and that the brightness of PGC 10800 is too weak, according to his writings . Professor Seligman also says that NGC 1135 and NGC 1136 are one and the same galaxy, namely PGC 10807.
