释义
Taurid meteors

Astronomy
  • A moderate meteor shower, producing steady activity from October 1 to November 25 from two principal radiants. The parent body is Comet Encke. The maximum is broad and flat, with the Northern Taurid radiant peaking around November 12 from RA 3h 52m, dec. +22°, close to the Pleiades, while the Southern component peaks around October 10 from RA 2h 08m, dec. +9°. Peak activity typically reaches a ZHR around 10. The shower’s long duration and comparatively low activity indicates that the meteor stream is ancient and well-dispersed. Taurid meteors are slow (geocentric velocity 28 km/s). Combined with a reasonable proportion of negative-magnitude events, often of long duration, this has led to the shower acquiring a reputation as a rich fireball source. See also beta taurids.
