The Ursids, or Ursid meteor shower, are an annual meteor shower that coincides with the winter solstice.

The Ursids occur from December 17 to 25 and peak just before Christmas, around December 22, with a zenithal hourly rate of 10 meteors per hour. The meteor shower was named for its radiant point, or apparent point of origin, which lies in the direction of the bright star Kochab in Ursa Minor.

Perseid Meteor Shower

The Perseid meteor shower is an annual meteor shower that occurs from July 23 to August 20. The meteor shower is associated with the comet Swift-Tuttle. It peaks around August 12-13 every year.

The Perseids are also sometimes called the “tears of St. Lawrence” because they peak near the date of the saint’s martyrdom, August 10.

The shower’s name is partly derived from the Greek Περσείδες (Perseides), a term from Greek mythology meaning “the sons of Perseus.” The meteor shower is associated with Perseus because the radiant, or the point from which the Perseids appear to come in the sky, is located in the direction of Perseus constellation. The name Perseids is pronounced /ˈpɜrsiːɨdz/.
