C/1739 K1 is a parabolic comet that was discovered by Italian astronomer Eustachio Zanotti in 1739. It is the parent body of the Leo Minorids meteor shower.
Zanotti spotted the comet in the constellation of Lynx on 27 May. He descripted as a magnitude 3 star surrounded by nebulosity while as seen from a telescope a tail 2 degrees long was spotted. Zanotti followed the comet with naked eye until 17 August, when it was only visible via a telescope. He last spotted the comet the next day. The comet was also observed by James Bradley from 30 May to 10 June and Fuhrmann from June 8 to June 19.
The parabolic orbit calculated by Nicolas-Louis de Lacaille indicates it passed perihelion on 17.9 June. The comet had passed at a distance of 0.45 AU on 16 April 1739. The comet has a minimum orbital intersection distance with Earth of 0.049 AU and has been associated with the Leo Minorids meteor shower.
