Notable deep sky objects

As the milky way runs through Puppis, there are a large number of open clusters in the constellation. Messier 46 (M46) and Messier 47 (M47) are two open clusters in the same binocular field. M47 can be seen with the naked eye under dark skies, and its brightest stars are 6th magnitude. Messier 93 (M93) is another open cluster somewhat to the south. NGC 2451 is a very bright open cluster containing the star c Puppis.

On November 14, 2007, Nova Puppis 2007, or V597 Pup, was discovered about 1 degree northeast of RS Puppis, a Cepheid variable. The coordinates are RA = 8:16.3, DEC = -34°15', J2000.0 standard. On the Puppis map at right, that is approximately two thirds the distance from ρ Pup to ζ Pup.

Planetary systems

Several extrasolar planet systems have been found around stars in the constellation Puppis, including:

  • On April 18, 2006, HD 69830 (the nearest star of this constellation) was discovered to have three Neptune-mass planets, the first multi-planetary system without any Jupiter-like or Saturn-like planets. The star also hosts an asteroid belt at the region between middle planet to outer planet.
