NGC 2452 is a planetary nebula located in the southern constellation of Puppis. NGC 2452 was discovered by Sir John Herschel in 1847.^[3]

NGC 2452 is located about 15,000 light-years (4.7 kiloparsecs) away from the Earth, and is about 40 to 50 thousand years old. In the sky, it appears close to the open cluster , and was previously thought to be a possible member of that cluster. However, it is merely a coincidence, and they are unrelated to each other; NGC 2452 is a foreground object relative to NGC 2453.^[2]

The central star of NGC 2452 has a spectral type of [WO1],^[1] and its progenitor would have had a high mass of about 7 M_☉, close to the upper limit of planetary nebula formation.^[2]
