At its greatest brightness in October, 2P/Encke will be visible in the morning sky just before sunrise. It’s not expected to be visible to the naked eye but might become observable through binoculars.

Description: 2P/Encke has the shortest orbital period of any known comet — about 3.3 years. This comet was first observed by French astronomer Pierre Méchain on January 17, 1786, but got its name after German astronomer Johann Franz Encke, who calculated its orbit in 1819.
