What are the three major meteor showers in the northern hemisphere?

Quadrant meteor shower, Perseid meteor shower, Gemini meteor shower.

The quadrant meteor shower is a relatively large meteor shower, which occurs at the beginning of each year. Quadrant is an ancient constellation, but there is no such constellation in the division of modern constellations. Its position is roughly between Shepherd and Draco, and the declination can reach about 50 N.

Perseid meteor shower, also known as Perseid gamma meteor shower, is a meteor shower with the radiation point near Perseid gamma star. It appears from July 20th to August 20th every year, and reaches its climax in August 13.

Gemini meteor shower is caused by asteroid Phaeton. The asteroid Phaeton passes near the earth every year, and the debris falling from the planet will fall into the earth's atmosphere under the influence of the earth's gravity, and then be pneumatically heated and burned to form a meteor.

Extended data

Quadrant meteor shower is an abandoned constellation. The original name of meteor shower is "Draco Meteor Shower", and its radiant point was originally located in Draco, but now it has been moved to Pisces. The quadrant meteor shower, a traditional meteor shower with a large flow, is the strangest one for astronomers and astronomy enthusiasts, and even its parent comet is still a mystery until now.

One view is that the mother comets of the quadrant meteor shower are C//KOOC-0/490Y/KOOC-0/and C//KOOC-0/385U/KOOC-0/,but some scientists think that it was brought by the asteroid 2003EH/KOOC-0/. This meteor shower may be formed by the debris in orbit after the earth passed through the asteroid 2003 EH 1 (originally a comet, the loose material was blown away by the sun, and the remaining comet nucleus became an asteroid).
