Asteroid pair

A possible example of a pair are the Trojan asteroids 1583 Antilochus and 3801 Thrasymedes. The proposer of that pair, Andrea Milani, found five other potential asteroid clusters in the Greek camp, clustered around the asteroids 1437 Diomedes, 1647 Menelaus, 2456 Palamedes, 2797 Teucer and 4035 Thestor.

The youngest asteroid pairs discovered as of 2022 include the main-belt asteroids P/2016 J1-A/B (separated c. 2010) and (458271) 2010 UM₂₆/2010 RN₂₂₁ (separated c. 2003). The former pair is particularly remarkable for exhibiting comet-like activity due to water ice sublimation and rotational break-up.
