A lucky few will have a rare glimpse of one of the solar system’s outer planets disappearing behind Earth’s moon.

Uranus, which is visible only through a telescope, will disappear behind the moon during an occultation on Saturday (Jan. 28), and people in the far north of the world and a portion of Asia will have the chance to watch it.

At least part of the event will be visible in areas of Alaska, Canada’s very far north, Greenland, Russia and Japan, according to a visibility map from (opens in new tab). The occultation is listed at 10:28 p.m. EST Saturday, Jan. 28 (0328 GMT on Jan. 29) but visibility will vary by region.

There are no livestreams listed on YouTube yet, but if we spot one we’ll be sure to let readers know.

Occultations happen when one celestial body appears to pass behind another from the perspective of Earth, although in reality, Uranus and the moon are separated by many billions of miles (or kilometers). Uranus’ average distance from the sun is roughly 1.8 billion miles (2.9 billion km), according to NASA. That’s about 19 times the distance from the Earth to the sun.

“Lunar occultations are only ever visible from a small fraction of the Earth’s surface,” wrote. “Since the moon is much closer to the Earth than other celestial objects, its exact position in the sky differs depending on your exact location.”

Uranus is the first planet with a named discoverer, as it did not come to light until relatively high-powered telescopes were available. English astronomer William Herschel spotted spotted the planet on March 13, 1781 and suggested naming it after his patron, King George III. The name “Uranus” was suggested by German astronomer Johann Elert Bode, whose observations helped confirm the newly found object was a planet.

If you miss this occultation of Uranus due to cloudy skies or unlucky geography, there’s another opportunity coming up on Sept. 29 that will be visible from portions of Canada, eastern Alaska and the western United States, says (opens in new tab).
