WASHINGTON — When the Quadrantid meteor shower peaks on Friday, it will be the year’s first chance to see fireballs in the sky.
A waning crescent moon means good visibility under clear and dark conditions.
Most meteor showers are named for the constellations where they appear to originate from in the night sky. But the Quadrantids “take their name from a constellation that doesn’t exist anymore,” said NASA’s William Cooke.
These meteors usually don’t have long trains, but the heads may appear as bright fireballs. The peak may reveal as many as 120 meteors per hour, according to NASA.
Viewing lasts until Jan. 16. Here’s what to know about the Quadrantids and other meteor showers.
As the Earth orbits the sun, several times a year it passes through debris left by passing comets — and sometimes asteroids. The source of the Quadrantids is debris from the asteroid 2003 EH1.
When these fast-moving space rocks enter Earth’s atmosphere, the debris encounters new resistance from the air and becomes very hot, eventually burning up.
Sometimes the surrounding air glows briefly, leaving behind a fiery tail — the end of a “shooting star.”
You don’t need special equipment to see the various meteor showers that flash across annually, just a spot away from city lights.
The best time to watch a meteor shower is in the early predawn hours, when the moon is low in the sky.
Competing sources of light — such as a bright moon or artificial glow — are the main obstacles to a clear view of meteors. Cloudless nights when the moon wanes smallest are optimal viewing opportunities.
And keep looking up, not down. Your eyes will be better adapted to spot shooting stars if you aren’t checking your phone.
The Quadrantids will peak on a night with a slim crescent moon, just 11% full.
The next meteor shower, the Lyrids, will peak in mid-April.
