Overview
Up to the year 2200, its closest approach to any major planet will be on February 3, 2120, when it will still be 2.669 AU (399,300,000 km; 248,100,000 mi) from Jupiter.[2]
With an IRAS diameter of 126 km,[1] Anchises is about the 7th largest Jupiter Trojan known.[3] It is a dark P-type asteroid.[1]
