Its velocity relative to the cosmic microwave background is 105.1 ± 7.4 km/s, which corresponds to a Hubble distance of 105.1 ± 7.4 Mpc (~343 million ly).

[1] NGC 2937 was discovered by German astronomer Albert Marth in 1864.

The shape of NGC 2936 has earned it the nickname of the "porpoise galaxy".
