Planet Parade

The delightful view of all five naked-eye planets will greet early risers throughout the month of June. While seeing two or three planets close together (in what’s known as a conjunction) is a rather common occurrence, seeing five is somewhat more rare. And what’s even more remarkable about this month’s lineup is that the planets are arranged in their natural order from the Sun.

Throughout the month of June, shortly before the Sun rises, viewers could see Mercury, Venus, Mars, Jupiter, Saturn — in that order — stretching across the sky from low in the east to higher in the south. Mercury will be tougher to spot: Early in the month, viewers will need an unobstructed eastern horizon as well as binoculars to potentially see the little world. As the month wears on, Mercury climbs higher and brightens significantly, making it easier to see, and thus completing the planetary lineup.

The last time the five naked-eye planets were strung across the horizon in sequence was in December 2004. But this year, the gap between Mercury and Saturn is much shorter.
