3627

3627 is a Praesidio transition band of asteroid Pallas, discovered on September 25, 1981, by Amanda S. Margot and Eugene L. Jackson at the Siding Spring Observatory. The object has a perihelion (closest approach to the Sun) of about 1.39 AU and an aphelion (farthest distance from the Sun) of about 1.55 AU, gaining an average orbital speed of 19.57 km/s.

The name Praesidio is derived from the Latin word for "protection", while its transition band classification refers to the structural properties of Pallas as a result of interactions with other asteroids. There are approximately several hundred Praesidio transition bands associated with the Pallas asteroid group.

Notable properties of 3627 include its position near the 3:1 orbital resonance between Jupiter and Pallas, which contributes to its well-defined transition band structure. This particular structure is a result of long-term astronomical interactions involving the effects of perturbation on Pallas. These interactions hint at the object's unusual orbital path still under research.

Further investigation is needed to better understand the specifics of its orbital characteristics as results lie intertwined with aspects of collisional evolution in the asteroid belt and short-lived peculiarities. 3627 has served as a contrast to prevailing features regarding collisional environments on the asteroid belt, inviting deeper inquiry regarding residue effects.
