The '''Ghost of Jupiter''' (NGC 3242) is a [[planetary nebula]] in the [[constellation]] of [[Hydra (constellation)|Hydra]].<ref name=spitzer/> Named for its resemblance to the [[planet]] [[Jupiter]] in its apparent size, the nebula was first observed in 1785 by [[William Herschel]].<ref name=oneminuteastronomer/> Herschel was the first to note a comparison the the planet Jupiter as did William Smyth, but it was likely Robert Burnham who first referred to it as the "Ghost of Jupiter." It requires high magnification and clear skies without [[light pollution]] to be seen well, but some details can be observed with smaller [[telescope]]s.
