Introduction to the Ursid meteor shower
The parent comet of the "Ursids" is 8p/Tuttle, and its active period is generally from December 17th to 26th every year.It is named because the radiant point of the meteor shower is close to the β star in the constellation Ursa Minor (known as the North Pole II or Emperor Star in ancient China).The Ursa Minor meteor shower was discovered by William F.Denning in the middle of the 20th century.As the meteor group with the highest declination of the radiant point, the Ursa Minor meteor shower has a small flow rate of about 10 to 50 per hour, but it is very suitable for observation in the middle and high latitudes of the northern hemisphere.
