The showers began Saturday, but will peak on the evening and dawn of Dec. 13-14, according to earthsky.org. They end on Dec. 17. If it’s dark, you could see as many as 50 flaming meteors cross the sky per hour, with the most around 2 a.m.
Meteors become visible between about 75 to 120 km (250,000 to 390,000 ft) above Earth. For bodies with a size scale larger than 10 cm (3.9 in) to several meters meteor visibility is due to the atmospheric ram pressure (not friction) that heats the meteoroid so that it glows and creates a shining trail of gases and melted meteoroid particles.
Meteoroid: A “space rock”—a relatively small object traveling through space, between the size of a grain of dust and a small asteroid. Meteor: A meteoroid that enters Earth's atmosphere and burns up. Meteorite: A meteoroid, especially one that has hit Earth's surface.
