Unidentified planetoid near Venus
A body large enough to be a satellite was seen near Venus from Naples by the astronomer Francesco Fontana. He made further observations of the “satellite” on December 25th 1645 and January 22nd, 1646. Jean-Charles Houzeau, director of the Royal Observatory of Brussels, baptized the satellite with the name “Neith” in the 1880s.
