It is located about 2° south and slightly west of the 4th-magnitude star Mu (μ) Hydrae. It's sometimes called the Ghost of Jupiter because it's similar in size and color to the planet Jupiter. The total light of NGC 3242 roughly equals that of an 8th-magnitude star.

WebThe colorful Cat's Eye Nebula is a planetary nebula. Planetary nebulae are formed in the wake of white dwarfs. Nebulae can also form as a result of a huge star or white dwarf going supernova. For example, The Crab Nebula was created by a supernova in 1054. Nebulae can form stars, such as the Crab Pulsar created within the Crab Nebula. tim mcgraw\u0027s daughter gracie katherine mcgrawWebA photo of IC 1396 (emission nebula) in Cepheus showing the Red Supergiant star, Mu Cephei.
