Discovered by William Herschel in 1786.
Planetary nebula NGC 2438 appears superimposed over the open star clusterM46, although it is almost certainly no member of the cluster, but a foreground object (see M46 for details). It is one of the discoveries of William Herschel, who cataloged it as H IV.39.
Our image was obtained by David Malin of the Australian Astronomical Observatorywith the 3.9-meter Anglo-Australian Telescope. The image is a 3-color composit created from red, green and blue photographic plates. The faint central star appears close to a background star, which is probably a member of M46, as many of the other stars in the image.

The central star of NGC 2438 is of magnitude 17.5 and exhibits a continuous spectrum.
Long exposures by David Malin with the Anglo-Australian Telescope have shown that this planetary has an extended halo, extending somewhat beyond its apparent diameter of 66".
