3360 Syrinx (originally designated 1981 VA) is an Apollo and Mars crosser asteroid discovered in 1981. It approaches Earth to within 40 Gm three times in the 21st century: 33 Gm in 2039, 40 Gm in 2070, and 24 Gm in 2085.
On 20 September 2012, it closely encountered Earth at a distance of 0.4192 AU (62,710,000 km; 38,970,000 mi),[2] peaking in brightness at an apparent magnitude of 17.0.[3] In opposition on 23 November 2012, it brightened to magnitude 16.0.[3]
It is a member of the Alinda group of asteroids with a 3:1 resonance with Jupiter that has excited the eccentricity of the orbit over the eons.[4] As an Alinda asteroid it makes approaches to Jupiter, Earth, and Venus.[2]
For a time, it was the lowest numbered asteroid that had not been named. In November 2006, this distinction passed to 3708 Socus, and in May 2021 to (4596) 1981 QB.[citation needed]
