The shower’s odd origins
If the meteor shower’s name seems unusual, it’s probably because the name doesn’t sound as if it’s related to a constellation. That’s because the Quadrantids’ namesake constellation no longer exists — at least, not as a recognized constellation.

The constellation Quadrans Muralis, first observed and noted in 1795 between Boötes and Draco, is no longer included in the International Astronomical Union’s list of modern constellations because it’s considered obsolete and isn’t used as a landmark for celestial navigation anymore, according to EarthSky.

The radiant point of the shower is a right angle between the Big Dipper and the bright star Arcturus, according to EarthSky. But the meteors will be visible in all parts of the sky, so it’s not necessary to look only in that direction.

Like the Geminid meteor shower, the Quadrantids come from a mysterious asteroid or “rock comet,” rather than an icy comet, which is unusual. This particular asteroid is 2003 EH1, which takes 5.52 years to complete one orbit around the sun and measures 2 miles (3.2 kilometers) across.
But astronomers believe a second object, Comet 96P/Machholz, may also contribute to the shower, according to EarthSky. The comet orbits the sun every 5.3 years.

Scientists think a larger comet was gravitationally bound into a short orbit by the sun around 2000 BC. The comet left behind meteors for years before breaking apart sometime between the years 100 and 950. As a result, the comet left behind many celestial offspring known collectively as the Machholz Complex, which includes the Quadrantid meteor shower’s parent bodies Comet 96P/Machholz and asteroid 2003 EH1, as well as two different comet groups and eight meteor showers, according to EarthSky.
