Night Sky News: See the Tightest Planet Gathering Yet This Century

Talk about an early morning eye-opener! Every day this month, about 20 to 45 minutes before sunrise, sky-watchers will get a rare opportunity to watch four worlds—Mercury, Venus, Mars, and Jupiter—in the closest planetary grouping yet seen this century.

This, planetary conjunction—astro-lingo for when planets cluster together in the heavens—has provided some impressive sights already. But the early-bird sky show is really culminating this week as they form their tightest grouping yet!

Jupiter, the gas giant and second brightest of the bunch, will glide past Venus on May 10 and 11, making the larger world easy to spot despite it being less than a quarter as bright as the goddess of love. Most impressive is that the two planets will be separated by only  0.5 degrees, which means you could easily cover the starlike pair with just your thumb on an outstretched arm.

Then, on May 12 all four worlds will be clustered within 6 degrees of each other in the dawn sky. That’s equal to the width of 12 full moon disks side by side—quite a pretty sight.

Faint little Mercury is the third brightest planet in the parade, just to the lower right of the Venus-Jupiter pair. But what makes it a challenging target is that Mercury is five to ten times fainter than Jupiter and much closer to the horizon. The innermost planet will remain a few degrees to the lower right of the brighter Venus throughout this period.

However, ruddy colored Mars is the trickiest to spot because it’s just one-hundredth as bright as Venus. The red planet starts very low in the sky, but eventually catches up with the Venus-Mercury pairing this week.

Your best bet to pick out Mercury and Mars through the bright twilight is by using binoculars when you scan just below Venus.

While this planetary alignment can be glimpsed from around the world, best views will be centered around the tropics, where the planets will shine brighter and higher in the predawn sky.

For observers in mid-latitude regions such as southern Canada, most of the continental U.S., and Europe, the planets will hug the eastern horizon very closely, making it more of a challenge to see the entire set.

No matter where you are, the most important advice is to get a clear, unobstructed view of the low eastern horizon 30 to 45 minutes before your local sunrise.

This dazzling planetary meeting will begin to slowly disband in the second half of May, but as a grand finale to the sky show, our own crescent moon will add to the mood from May 29 to 31, making for a picturesque pose with Jupiter and then Venus.

Sky-watchers haven’t seen a cosmic morning lineup like this since 1996! And if you miss this one, you will have a long wait, because the next big planetary conjunction—which will involve all five of the naked-eye planets, plus the moon—won’t occur until September 8, 2040.

Cosmic Gang of Four, Plus Two

While all the hoopla surrounds the four bright planets, there are two other members of the club getting in on the action.

Both Uranus and Neptune sit to the far upper right of the quadruple pack of planets in the southeastern sky. They are both significantly fainter, and so you will need binoculars to glimpse them.

Neither will look all that impressive, appearing as greenish-blue tinted, fuzzy stars. A small telescope, however, will begin to reveal their tiny disks.

Out of the eight official planetary members of our solar system, we are lucky enough to see six huddled together in one small section of the sky.

We live on one of the remaining member worlds, so that leaves one missing: Where is Saturn? The ringed gas giant sits by its lonesome in the evening sky, shining brightly high above the southern horizon.

    I saw them! on May 10. right minutes before sunrise from Sanur beach, Bali. Right above the horizon, east sky. At that time I know nothing if those three little stars I saw were Jupiter, Venus & Mercury.

    Andrew! you’re doing awesome work regarding this sky watching activities. Won’t miss you from now and on. Thank youu! 🙂

    There is no truth to the rumor that the mass and weight of so many of the planets all in one tiny corner of the solar system will cause it to tilt, and thence cause the Earth to roll at a very fast speed toward them, and either shoot out into space or even hit a couple of them. We have determined that the Earth will not smash into any of them, Repeat, the Earth will not collide with one or more of the other planets in that cluster, as best as we can determine. Thank you.

    I want to see 5 planets and 10 moons collide simultaneously like a billards rack exploding with a deafening *crack* and blinding light.
    Is that too much to ask for?
    Who asked you?

    i live in Sydney Australia, i wake up at 5.30 am to go to work. i used to see two bright stars on the east just before sunrise. but from some days i saw 2 more around. i took my iphone, opened the PLANETS App, then i knew they were mars, venus, jupiter and mercury. i found myself one of the lucky ones to have the chance to see all four that close (even with open eyes).

      Everyone around the world can see these planets in the morning sky – for those close to the tropics the planets will appear higher in the sky than for those observers in higher latitudes.

    Just like the planets, we follow their lead in clustering together.
    The cosmic gang of four plus two is very symbolic in its missing .
