===Planetary systems===
Several [[extrasolar planet]] systems have been found around [[star]]s in the constellation Puppis, including:
* On July 1, 2003, a [[extrasolar planet|planet]] was found orbiting the star [[HD 70642]]. This [[planetary system]] is much like [[Jupiter]] with a wide, circular orbit and a long-period.
* On May 17, 2006, [[HD 69830]] 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.
* On June 21, 2007, the first extrasolar planet found in the [[open cluster]] [[NGC 2423]], was discovered around the [[red giant]] star [[NGC 2423-3]]. The planet is at least 10.6 times the mass of Jupiter and orbits at 2.1 [[Astronomical Unit|AU]] distance.
* On September 22, 2008, two Jupiter-like planets were discovered around [[HD 60532]]. [[HD 60532 b]] has a [[minimum mass]] of {{Jupiter mass|1.03}} and orbits at 0.759 AU and takes 201.3 days to complete the orbit. [[HD 60532 c]] has a minimum mass of {{Jupiter mass|2.46}} and orbits at 1.58 AU and takes 604 days to complete the orbit.
* In 2023, Astronomers detected two [[ice giant]] type [[exoplanet]]s (both with a [[mass]] of tens of [[earth]]s) having a collision event around the 300 million year old [[star]] designated as [[2MASS J08152329-3859234]].
