Copenhagen, Denmark — 4 January 1768
Unidentified planetoid orbiting Venus
Astronomer Christian Horrebow reported an observation of “a small light, that was not a star” which appeared to be in orbit around Venus. This object, named “Neith” by M. Hozeau of Brussels observatory, was never identified with certainty and was certainly not a natural satellite.
