original question: How many meteor showers were spawned by [Halley's Comet]?
answer: 2
answer type: Meteor Shower.
auxiliary information: Halley's Comet or Comet Halley, officially designated 1P/Halley, is a short-period comet visible from Earth every 75‚Äì76 years. Halley is the only known short-period comet that is clearly visible to the naked eye from Earth, and the only naked-eye comet that might appear twice in a human lifetime. Halley last appeared in the inner Solar System in 1986 and will next appear in mid-2061. Halley's returns to the inner Solar System have been observed and recorded by astronomers since at least 240 BC. Clear records of the comet's appearances were made by Chinese, Babylonian, and medieval European chroniclers, but were not recognized as reappearances of the same object at the time. The comet's periodicity was first determined in 1705 by English astronomer Edmond Halley, after whom it is now named. During its 1986 apparition, Halley's Comet became the first comet to be observed in detail by spacecraft, providing the first observational data on the structure of a comet nucleus and the mechanism of coma and tail formation.
What was the total amount of meteor showers that [Halley's Comet] caused?
