Comet 46P/Wirtanen will pass within 12 million kilometers (7.4 million miles) of Earth on December 16, 2018.
Fortunately a Full Moon will distinctly dim your prospects of seeing that night as well as nights on either side even though the comet is expect to brighten to 3rd magnitude.
A finder char is found at Sky & Telescope’s web site from December 1st through January 3rd. On December 15th it will be found half way between the Hyades and the Pleiades. This is a fast moving comet.
