March 2031 Planet Parade: 5 planets in the evening sky

Mercury, Venus, Saturn, Uranus and Neptune share the evening sky around Mar 14, 2031. Below: what each planet looks like, how to catch the line-up, and how this parade compares with its neighbors.

A planet parade is a line-of-sight arrangement, not an event out among the planets themselves. Because every planet orbits in nearly the same flat plane, they always appear strung along one line in our sky, the ecliptic; a parade is just a spell when several of them sit above the horizon together. The bearings here are worked out for mid-northern latitudes (around 40°N), and your own view depends on where you stand, which the live tracker handles.

Planet by planet

Mercury hangs low, only about 7° up in the west, so it needs a flat, open horizon in that direction. Plenty of lifelong stargazers have never knowingly seen Mercury, and many observers still log their first certain sighting as a milestone.

Venus sits a comfortable 23° above the horizon in the west. Its cloud tops reflect about three quarters of the sunlight that hits them, which is why it outshines every star.

Saturn rides high, about 54° up in the west-southwest, well clear of any horizon haze. Even at its best Saturn is a modest golden point to the eye, and only a telescope reveals the rings that made it famous.

Uranus rides high, about 68° up in the southwest, well clear of any horizon haze. Uranus glows right at the naked-eye limit near magnitude 5.7, so it hides in plain sight until binoculars and a chart pin it down.

Neptune hangs low, only about 7° up in the west, so it needs a flat, open horizon in that direction. Neptune was found in 1846 exactly where mathematics said it would be, the first planet discovered by calculation rather than by accident.

On the zodiac that evening, Mercury, Venus and Neptune share Aries; Saturn and Uranus share Gemini. Signs here are the tropical longitudes the tables on this site use, counted from 0° at the spring equinox.

How to watch this parade

No alarm needed: start about 48 minutes after local sunset on Friday, March 14, 2031, once the twilight has faded enough for the planets to pop out one by one.

The limiting planet is Neptune at only about 7° up, so pick a viewing spot with an unobstructed view toward the west. The line stretches about 67° along the ecliptic, so sweep your gaze along the Sun's daily path to trace it.

One pairing stands out this time: Mercury and Neptune sit less than a degree apart, close enough to frame together in binoculars or a single photo.

You need no equipment for Mercury, Venus and Saturn; Uranus and Neptune are the reason to bring binoculars or a small telescope.

How good is this one?

Our tracker scores every parade from 0 to 100. This one rates 63 out of 100: 25 of 35 points for the number of planets, 15 of 25 for naked-eye planets, 13 of 20 for how tightly they group, 10 of 10 for altitude, and 0 of 10 for staying power.

The window is forgiving: good evenings run for roughly 10 weeks (Jan 12, 2031 to Mar 22, 2031), so one cloudy night costs you nothing. The previous parade over this reference location peaked in August 2030 with 5 planets; the next comes in May 2031 with 4 planets.

Does a parade do anything to Earth? Nothing at all; the alignment is only in our line of sight. Gravity falls off with the square of distance, and the planets are so far away that their combined tug is thousands of times smaller than the Moon's. It cannot budge a tide, let alone the weather. This is a view, not a force.

Frequently asked questions

Which planets are part of the March 2031 planet parade?

Mercury, Venus, Saturn, Uranus and Neptune. Mercury, Venus and Saturn are visible to the naked eye; Uranus and Neptune need binoculars or a telescope.

What time should I look for the March 2031 planet parade?

Start looking about 48 minutes after local sunset, with the best evening on Friday, March 14, 2031. Good evenings run from Jan 12, 2031 to Mar 22, 2031.

Do I need a telescope to see this planet parade?

Not for the highlights: Mercury, Venus and Saturn show with the unaided eye. You only need binoculars or a telescope for Uranus and Neptune.

Where in the sky should I look?

Face the western sky about 48 minutes after sunset. The planets sit between about 7° and 68° above the horizon, strung along the ecliptic.
