It is viewed nearly edge-on from Earth's location in space and is located between 16 and 25 million light-years away.
The reddened light from the center of the galaxy appears yellowish due to the intervening gas and dust located within the outer arms of NGC 2683. Its apparent magnitude is 10.6 making it not visible to the human eye without the aid of a small telescope.
While usually considered an unbarred spiral galaxy, recent research suggests it may in fact be a barred spiral galaxy; its bar is hard to see due to its high inclination. Further support for the presence of a bar stems from the X-shaped structure seen near its centre, which is thought to be associated with a buckling instability of a stellar bar.
It is also both smaller and less luminous than the Milky Way with very little neutral hydrogen or molecular hydrogen and a low luminosity in the infrared, which suggests a currently low rate of star formation.
Due to its vast distance and complexity (due to the association of Globular Clusters bound to it), NGC 2638's mass has not been calculated as accurately as it could be. Otherwise its volume and vector motions are reasonably well known and characterized.
