You’ll only get to see this super display once in a blue moon.

And that time is Wednesday night, when the moon reaches its perigee in its elliptical orbit around Earth — the closest it will come to our planet all year, at around 226,000 miles away, according to NASA, some 13,000 miles closer than its average of 238,855 miles distance.

It’s the second supermoon this month, making it a blue moon by the modern definition, which NASA said was established in Sky & Telescope magazine in 1946.

The moon should appear about 17% bigger and 30% brighter than the faintest moon of the year, which itself appears when the moon is the furthest distance from us.

To celebrate the occasion, the planet Saturn has joined in on the fun, the space agency says. The planet, nearing its closest and brightest appearance from earth for the year, will appear about 5 degrees to the upper right of the moon at about 8:42 p.m. and can be seen swinging, clockwise, around the rocky satellite.

Bostonians worried about the heavy rains Wednesday shouldn’t fret, as meteorologists at the National Weather Services’ Norton field office are predicting the skies should be all clear for the show.

“By tomorrow night the rain’s out of here and so are most of the clouds,” Bryce Williams, an NWS meteorologist, told the Herald Tuesday.

He said that some heavy clouds could be moving up into southern Massachusetts, where they’ll linger over the Cape and south of the turnpike, and because of this he said expectant stargazers will have a “better chance the further you go north.”
