Look up: There will be a full snow moon, an eclipse and a comet this weekend

It all starts Friday evening.

The sky will put on quite the celestial show this weekend.

There's a full moon (called a snow moon), a penumbral lunar eclipse and the chance to see a green comet streaking across the sky. Whoa.

Here's when you'll be able to see everything:

When the moon rises Friday evening, it'll be full. But the Earth's penumbral shadow (our planet's outer shadow) will be covering the face of the moon, causing a penumbral lunar eclipse, EarthSky.org says.

Space.com reports the moon will enter the Earth's shadow at 4:32 p.m. and leave at 8:55 p.m., with the peak of the eclipse at 6:43 p.m.

It's not that easy to see, though. The moon might look a little darker or shaded than a typical full moon, while others might not notice any difference, EarthSky notes. And it'll only really be visible in Minnesota at moonrise, so about 5:30 p.m., according to TimeandDate.com.

Cloudy skies above Minnesota Friday might make the full snow moon eclipse even harder to see. If that's the case, you can watch a live stream of it online here.

The comet

Then early Saturday morning, a green comet will fly by Earth at 51,000 mph, Sky and Telescope reports.

The comet – named Comet 45P/Honda-Mrkos-Pajdusáková – won't be nearly as bright as the green fireball that flew across the Midwest earlier this week, so you'll probably need binoculars or a telescope to see it, EarthSky says.

The best time to see the comet will be around 2 a.m. Saturday, when it makes its "closest" pass by Earth – it'll still be 7.7 million miles away, or about 32 times the distance between the Earth and the moon, Sky and Telescope says.

Comet 45P comes around every five years, The Associated Press says.

You can watch a live stream of Comet 45P online here, starting at 9:30 p.m. Friday.
