On Sunday, the comet known as 46P/Wirtanen will make one of the closest comet flybys of Earth in 70 years. You may be able to see it with your naked eyes. It’s already visible with binoculars. This time exposure image of the comet was taken on 2 December suing a 50 mm refractor telescope. The streak in the lower half of the picture was caused by an upper stage rocket body passing through the field of view during the 2 minute exposure.
