Photometric and spectroscopic analyses are made for the object NGC 2242, which was detected in a survey of emission-line galaxies by Liu et al. (1986). Luminosity and color distributions and a small heliocentric velocity (-30 km s-1) are all inconsistent with previous classifications as a galaxy. NGC 2242 is probably a planetary nebula located at ≡2 kpc from the sun and at ≡500 pc above the galactic plane. Characteristics and physical parameters of NGC 2242 are discussed in some detail.
