The Oak Ridge Observatory (ORO, code: 801), also known as the George R. Agassiz Station, is located at 42 Pinnacle Road, Harvard, Massachusetts.

Through its first 40 years, its primary research focus was on tracking minor planets and asteroids in the Solar System.

It also housed an 84-foot (26 m) steerable radio telescope once used in Project BETA, a search for extraterrestrial intelligence.

[3] The inner main-belt asteroid 4733 ORO, discovered at Oak Ridge in 1982, was named in honor of the observatory.

[4] In addition to the discoveries below, the Minor Planet Center inconsistently credits some asteroids such as 4760 Jia-xiang directly to the Harvard College Observatory although they have been discovered at Oak Ridge.
