In 1672, J.D. Cassini observed a small object near Venus. Venus had she a satellite? He watched again in 1686 and other astronomers also in 1740, 1759 and 1761. However, all observers did not see the object and some thought it was a reflection due to the brightness of Venus, near. This "satellite" was also observed in the nineteenth century and was named Neith.
The inability to calculate the orbit and find the right place of the suspected satellite led to abandon the idea of the existence of a satellite around Venus. However, in 2002, the discovery of the asteroid "2002 VE68" which has an orbit close to that of Venus, makes it a "quasi-satellite" of this planet.
