Crucids
The Crucids are a group of meteor showers associated with the constellation Crux (the Southern Cross), primarily visible in the Southern Hemisphere.[1] The most notable showers within this group include the Alpha Crucids (α-Crucids), first recorded in the early 20th century,[2] and the Gamma Crucids (γ-Crucids), an unexpected meteor shower discovered in 2021.[3]The Crucids are characterized by meteors with velocities around 55.8 km/s,[4] and are believed to be linked to Halley-type comets.
They typically occur between January and February, though activity levels vary from year to year.
