(30797) Chimborazo is a Middle Main Belt asteroid. It was discovered on February 4, 1989 by Belgian astronomer Eric Walter Elst at the La Silla Observatory of the European Southern Observatory in Chile (IAU code 809).

The asteroid belongs to the Eunomia family, a group named after (15) Eunomia, which is believed to include five percent of the asteroids in the main belt.[1] The timeless (non-osculating) orbital elements of (30797) Chimborazo are nearly identical to those of the smaller, judging from the Absolute Magnitude of 16.4 versus 14.3, asteroid (363608) 2004 FS148.[2]

(30797) Chimborazo was named after Ecuador’s Chimborazo stratovolcano on March 12, 2017.
