Leonids 2027

The fastest major shower, capable of rare storms of thousands per hour around its parent comet's 33-year cycle.

Maximum: November 17, 2027 Active: Nov 6 – Nov 30
Viewing from New York

The Leonids reach maximum on November 17, 2027, with a peak rate of up to 15 meteors per hour under ideal dark skies (active Nov 6 – Nov 30). A bright 78%-lit Waning Gibbous is up through much of the peak night and will drown out all but the brightest meteors. A poor year. Rates stay elevated for several nights either side of the maximum, so you do not need to catch the exact peak night.
