Early risers will have one more chance to see five planets align in the sky, a rare astronomical event.

After Saturday, 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, Accuweather recommends heading outside 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.
