A fairly bright comet makes its closest approach to Earth on Wednesday, though it may be difficult to spot without clear conditions well away from city lights.

For a few nights at midweek, Comet 103P/Hartley 2 will be perfectly placed in the northeastern sky, in bright circle of stars that form the constellation Capella.

This sky map shows where to look to spot the comet, weather and lighting conditions permitting. Binoculars or a small telescope are advised to obtain the best viewing conditions. [ MSNBC ]
