Fireballs expected to blaze across the sky

In this 30 second cameras exposure, a meteor streaks across the sky during the annual Perseid meteor shower from Spruce Knob, W.Va.

The Geminid meteor shower — always a highlight of the meteor year — is expected to peak Monday night into Tuesday morning, with prime viewing opportunities arriving from 3 a.m. to dawn.

“The Geminids are a reliable shower for those who watch around 2 a.m. local time from a dark-sky location. We also often hear from those who see Geminid meteors in the late evening hours,” according to EarthSky.

“But this year, a waxing gibbous moon will be above the horizon during peak time for viewing. And it’ll set shortly afterwards, leaving the sky dark for watching meteors. Thus, the best time to watch for Geminid meteors in 2021 is likely before dawn — say, from around 3 a.m. to dawn — on Tuesday morning (or Wednesday morning, if you must).

“If you miss the Monday night and Tuesday morning, you could also try Wednesday morning, shortly before dawn breaks.”

About 50 meteors per hour is a good show for the Geminids, but on a particularly dark night that can climb as high as 150 per hour.

The shower could produce some meteors known as earthgrazers. Those are slow-moving, long-lasting meteors that appear the cross the night sky from horizon to horizon.

The Geminid meteors appear to radiate from within the constellation Gemini in the southwestern sky, but the optimum viewing position is reclined and looking straight up to view as much of the nightsky as possible.

The meteors in the upcoming shower are debris left behind by near-Earth object 3200 Phaethon, an asteroid that long ago may have collided with some similar object. Phaethon continues to circle the Sun in a 1.4-year orbit.

The Geminid meteor shower was first recorded in 1833 by observers on a Mississippi riverboat.

It’s growing steadily stronger as Jupiter’s gravity pulls the stream of debris closer to Earth, according to NASA.
