 Comet 46P/Wirtanen will pass very close to Earth next December. Its maximum approximation is calculated at 11.5 millions of km (0.0775 UA) on December 16 reaching a estimated magnitude 3.5, which indicates that it can be seen with the naked eye.

Comet 46P/Wirtanen is a short-period comet with an orbital period of 5.4 years. The comet is relatively small in size with an estimated diameter of just 1.2 kilometres. The object was the original target for ESA’s Rosetta spacecraft but the launch window was missed so 67P/Churymov-Gerasimenko was Rosetta's target in the end.
