Comet Finlay, also known as 15P/Finlay, is a Jupiter-family comet with an orbital period of 6.58 years. It discovered by William Henry Finlay from the Royal Observatory at Cape of Good Hope, South Africa on 26 September 1886. Of the known numbered periodic comets, the orbit of 15P/Finlay has one of the smallest minimum orbit intersection distances with Earth's orbit (E-MOID). In October 2060, the comet will pass about from Earth.
