Named meteor showers recur at approximately the same dates each year. They appear to radiate from a certain point in the sky, known as the radiant, and vary in the speed, frequency and brightness of the meteors. As of November 2019, there are 112 established meteor showers. Table of meteor showers Dates are given for 2021. The dates will vary from year to year due to the leap year cycle. This list includes showers with radiants in both the northern and southern hemispheres. There is some overlap, but generally showers whose radiants have positive declinations are best seen from the northern hemisphere, and those with negative declinations are best observed from the southern hemisphere.
