Tonight’s sky offers a spectacular show: the annual Geminids meteor shower reaches its peak on Saturday evening, painting the darkness with bright, yellow streaks.
The Geminids are among the most prolific showers, with NASA estimating roughly 120 meteors per hour during their zenith. Unlike most showers that spring from icy comet debris, this one stems from Asteroid 3200 Phaethon, a modest rock just 3.17 miles across.
Stargazers in the Northern Hemisphere enjoy the best viewing conditions, but observers as far south as the Southern Hemisphere will also witness the display.
Asteroids differ markedly from comets: they are primarily rocky and metallic, residing chiefly in the belt between Mars and Jupiter, whereas comets are composed mostly of ice and release gases when near the Sun.
NASA describes Phaethon as a potential “dead comet,” a relic that may still shed dust despite lacking the classic icy makeup of active comets.
For the best experience, lie flat on your back with your feet pointing south. After about 30 minutes in darkness, the sky should light up with meteors that continue streaking until dawn.
Frequently Asked Questions
When does the Geminids meteor shower peak?
The peak occurs on Saturday evening, offering the highest density of visible meteors.
How many meteors can observers expect to see?
NASA reports an estimated rate of 120 meteors per hour at the shower’s maximum.
What is the source of the Geminids?
The meteors originate from Asteroid 3200 Phaethon, a small rocky body that NASA suggests may be a “dead comet” or “rock comet.”
