Neith (hypothetical moon)
Neith is a non-existent moon of Venus reportedly sighted first by Giovanni Cassini in 1672 and by several other astronomers in the following years.
==Discovery==
In 1672, Giovanni Cassini found a small object close to Venus. He did not take great note of his observation, but when he saw it again in 1686, he made a formal announcement of a possible moon of Venus. The object was seen by many other astronomers over a large period of time: by James Short in 1740, by Andreas Mayer in 1759, by Joseph Louis Lagrange in 1761, another eighteen observations in 1761, including one in which a small spot was seen following Venus while the planet was in transit across the Sun, eight observations in 1764, and by Christian Horrebow in 1768.
