Meteor showers 2020: 8 peak dates, 5 under dark skies
The 8 major annual showers peak between 3 January 2020 and 22 December 2020 in 2020. 5 of them fall when the moon is near new and the sky stays dark; the other 3 compete with moonlight.
When is the next meteor shower?
Every 2020 peak has passed. The last was the Ursids on Tuesday, 22 December 2020. The cycle restarts with the Quadrantids in the first days of January.
Which meteor shower is best in 2020?
Two showers dominate most years: the Perseids in August and the Geminids in December. In 2020 the Perseids peak on Wednesday, 12 August 2020 with a last quarter, and the Geminids on Monday, 14 December 2020 with a waning crescent. Both fall in dark skies this year, which is the best pairing the calendar offers. The Geminids peak 7 days before the December solstice, which puts them in the longest nights of the northern year.
Will the moon spoil the 2020 showers?
Moonlight is the single biggest thing an observer cannot control, and it is entirely predictable. A shower peaking within about a week of new moon gets a dark sky; one peaking near full moon loses most of its fainter meteors to the glare. In 2020, 5 of the 8 major peaks fall in the dark half of the cycle: Lyrids, Perseids, Orionids, Leonids, Geminids. The remaining 3 contend with moonlight: Quadrantids under a first quarter, Eta Aquariids under a waxing gibbous, Ursids under a first quarter.

How do meteor shower peak dates work?
A meteor shower is the Earth ploughing through a trail of dust left by a comet or, in the case of the Geminids, an asteroid. Because the Earth returns to the same stretch of its orbit at the same time each year, the peak recurs on roughly the same calendar date. Roughly, not exactly: the orbit is not a whole number of days long, leap years nudge the calendar back into line, and the debris itself drifts. That is why published peaks move by about a day between sources and between years, and why observers are given a window rather than a moment.
The radiant is the point the meteors appear to stream from, an effect of perspective rather than a real location in space. Showers are named for the constellation holding that point, which is why the Perseids radiate from Perseus and the Geminids from Gemini. You do not need to look at the radiant to see them; meteors appear all over the sky and are often longer further from it.
