Saturday morning marks last chance to clearly see 5 planets align until 2018

For the next two mornings, early risers will have the chance to see five planets align in the sky, a rare astronomical event.

After Saturday, Feb. 20, the spectacle won't occur with such pristine views for another three years.

Mercury, Venus, Mars, Jupiter and Saturn have aligned each morning since Jan. 20, treating stargazers to a stunning sight.

For the best views, head outside an 60 to 90 minutes before sunrise. Any earlier and the planets won't be above the horizon, keeping them out of sight. Any later and the sun will be too bright, washing out the glow of the planets.

Uranus and Neptune may also be visible in the first half of the night with the use of a telescope or binoculars.

Venus is usually the easiest planet to spot when the skies are clear as it is the second-brightest object in the night sky after the moon.

This bright planet can serve as a guide to finding Mercury, the dimmest of the five planets, and Saturn, the second dimmest.

While Mercury, Venus and Saturn are clustered over the southeastern horizon, Mars and Jupiter will be visible higher up in the sky to the south and southwest. While Mars may not be as bright as Jupiter, its distinct red glow makes it easier to spot.

"Storms will hit on each side of the country on Friday, leading to cloudy skies in the Northeast and Northwest," AccuWeather Meteorologist Chyna Glenn said.

Sun and clouds will mix in the Plains and Midwest on Friday morning. In the Southeast and Southwest, clear skies will lead to ideal views.

Skywatchers in the Northeast may be out of luck as clouds will hold into Saturday morning, Glenn said. Cloudy skies will unfold across the mid-Atlantic and south-central U.S. as well.

"Sunshine is expected in the Southwest, central Plains and Southeast for Saturday morning," she said.

This event was the first time since 2005 that all five planets aligned.

Onlookers might may be able to catch the planets aligning again over the summer, according to EarthSky. From Aug. 13 to Aug. 19, all five may be visible in the evening.

However, Mercury and Venus will sit low in the sky, making it more difficult see them during the summer months than during the winter months.
