Named meteor showers recur at approximately the same dates each year. ... "2019 Meteor Shower Calendar" (PDF). International Meteor Organization.
The radiant also moves slightly from night to night against the background stars (radiant drift) due to the Earth moving in its orbit around the Sun. See IMO Meteor Shower Calendar 2017 (International Meteor Organization) for maps of drifting "fixed points". When the moving radiant is at the highest point, it will reach the observer's sky that ...

The Orionids meteor shower is produced by Halley's Comet, which was named after the astronomer Edmund Halley and last passed through the inner Solar System in 1986 on its 75–76 year orbit. [10] When the comet passes through the Solar System, the Sun sublimates some of the ice, allowing rock particles to break away from the comet.
2019 was predicted to be the closest post-perihelion encounter with Earth since 1975. The Taurid swarm was expected to pass 0.06 AU (9,000,000 km; 5,600,000 mi) below the ecliptic between June 23 – July 17.
The Leonids are famous because their meteor showers, or storms, can be among the most spectacular. Because of the storm of 1833 and the developments in scientific thought of the time (see for example the identification of Halley's Comet), the Leonids have had a major effect on the scientific study of meteors, which had previously been thought to be atmospheric phenomena.
The Alpha Monocerotids is a meteor shower active from 15 to 25 November, with its peak occurring on 21 or 22 November. The speed of its meteors is 65 km/s, which is close to the maximum possible speed for meteors of about 73 km/s (see Specific energy#Astrodynamics).
The comet has also being suggested to be the parent body of the lambda Draconids, which is active from April 24 to June 4, and peaks around May 12. However it is possible that it is the same shower as the Camelopardalids. [20] 209P/LINEAR may also be the source of the weak 6–14 June meteor shower "sigma Ursae Majorids" (SIM #677). [11]
