A newly discovered astral body, Comet C/2022 E3 (ZTF) will reach the closest point to Earth in its orbit — 27 million miles away — on Wednesday and Thursday.

  • The comet — also known as the "Green Comet" — was last seen in our skies 50,000 years ago.

Details: Weather permitting, it will be visible from Seattle with the naked eye all this week.

  • The comet can be seen in the northern sky between Ursa Major and Ursa Minor.
  • It will look like a fuzzy green object about 5 degrees below Polaris, National Weather Service forecaster Dustin Guy told Axios Seattle.

What we're watching: While the comet will be closest tomorrow and Thursday, the chance for overcast skies is expected to increase throughout the week.

Of note: If you really want to be sure to see the comet, Guy suggests heading east over the Cascades where the sky should be clear.

Editor's note: This article has been corrected to reflect that the Green Comet was last seen 50,000 years ago (not that it will be seen again in 50,000 years).
