Saturday Comet 45 P will be the closest to earth and possibly visible without binoculars or a telescope. It has been visible for the past two months with those tools.
The comet will be 7.4 million miles away from earth. Binoculars may be necessary to see the bright blue, green head and tail shooting across the sky.
The streak of ice can be seen looking east toward the Hercules Constellation at 2 a.m. Saturday morning.
