From January 20 to February 20, you can see five planets spanning the sky together just before dawn: Mercury, Venus, Saturn, Mars and Jupiter will all be visible about 45 minutes before sunrise.

This is the first time all five of the so-called naked-eye planets have appeared together in the pre-dawn sky in more than a decade, according to Sky and Telescope.

The group got the name "naked-eye planets" because you can see each of them with your own eyes -- you don't need binoculars or a telescope.

But that doesn't mean they're all easy to find. If you don't do a lot of skywatching, it can be confusing to pick the planets out of a sky filled with stars. Here are some tips to make it easier:

First, figure out when sunrise is for your area. The U.S. Naval Observatory has an easy tool.

Also, to help you get your bearings and to make it easier to find the planets, download an astronomy app and get used to using it inside the house before you head out into the cold.
