46P/Wirtanen is a short-periodic comet with an orbital period of 5.4 years. It was discovered by Carl A. Wirtanen in 1948 at the Lick Observatory. It belongs to the Jupiter family of comets, all of which have aphelia between 5 and 6 AU. Its diameter is estimated to be 1.2 kilometres. 46P/Wirtanen was the original target for the Rosetta spacecraft, but an inability to meet the launch window led to Rosetta being sent to 67P/Churyumov–Gerasimenko instead. This image was taken on January 8th 2018.
