Jupiter to Make Its Closest Approach to Earth in Decades on Monday

According to researchers, this will be the closest Jupiter will come to Earth until at least 2129

Amateur astronomers and the public alike will be treated to a special celestial show Monday night, as the solar system’s largest planet will be close enough that its features can potentially be seen with just a pair of binoculars.

According to NASA, Jupiter will reach “opposition” on Monday, meaning that it will be on the complete opposite side of Earth as the sun. As the sun sets, Jupiter will rise in the east, and it will be one of, if not the brightest, object in the night sky aside from the moon.

Chicago's Adler Planetarium noted that Jupiter will be visible for most of the night, but will reach its highest point around midnight.

NASA says that Jupiter’s opposition occurs every 13 months.

Reaching opposition is what will make Jupiter appear so brightly in the sky, but the bigger story is that the planet will also be at its closest point to Earth since at least 1963, according to NASA scientists.

On Monday, Jupiter will be approximately 367 million miles away from Earth, a distance close enough that NASA scientists believe that residents will be able to see some of the planet's bands, as well as a select cluster of its largest moons, through a pair of good binoculars.

Adam Kobelski, a research astrophysicist at the Marshall Space Flight Center in Huntsville, says that residents who want the best view of the planet should find a spot with a high elevation and plenty of dark skies.

A “good pair of binoculars” should be enough to see bands on the surface of Jupiter, as well as three or four of the planet’s more than six-dozen moons, according to Kobelski.

It's not quite clear if you'll be able to see it in the Chicago area, as a band of clouds from the northwest are expected to make for a partly cloud to even mostly cloudy evening.

The combination of Jupiter being at opposition and being so close to Earth is a rare one, and according to researchers at Scotland’s Astronomical Society of Edinburgh, this will be the closest Jupiter will come to Earth until at least 2129.

It's not the only thing to watch for in the sky Monday night, however.

In the first-of-its kind, save-the-world experiment, NASA is also expected to clobber a small, harmless asteroid millions of miles away.

A spacecraft named DART, for Double Asteroid Redirection Test, will zero in on the asteroid Monday, intent on slamming it head-on at 14,000 mph (22,500 kph). The impact should be just enough to nudge the asteroid into a slightly tighter orbit around its companion space rock — demonstrating that if a killer asteroid ever heads our way, we’d stand a fighting chance of diverting it.

“This is stuff of science-fiction books and really corny episodes of “StarTrek” from when I was a kid, and now it's real,” NASA program scientist Tom Statler said Thursday.

Cameras and telescopes will watch the crash, but it will take days or even weeks to find out if it actually changed the orbit.
