How to watch: Geminid meteor shower to peak Monday night
PHILADELPHIA - If you’re outside overnight, look up. You might see a shooting star!
Every December, the Earth runs into asteroid dust.
The dust, often the size of a grain of sand, add energy to the air way up in our sky. We’re talking about the air that’s like 50 to 80 miles above us.
Air there isn’t designed for that extra energy, so that air gives off that extra energy as light, the light you see as a "shooting star".
Now, nothing is actually burning up. You’re just seeing air give off a glow of light.
Instead, the rock dust ends up disappearing into thin air, quite literally.
Already super tiny to begin with, air resistance helps those specks of asteroid break up more and more as they fall. That air resistance (friction) also heats up those tiny rock pieces. Eventually, the pieces get warm enough that they vaporize: the become so tiny, they’re considered a gas.

You’ll see shooting stars for about two weeks before and after a meteor shower, but they’ll be pretty infrequent unless it’s the night of peak.
The Geminid Meteor Shower peaks at 2 a.m. Tuesday morning, but the best time to head out is from 3-6 a.m. Here’s why: there won’t be moonlight then.
Moonlight is the enemy of a meteor shower because they’re easier to spot when the skies are completely dark. The moon will set around 2 a.m., so it’ll be pretty dark by 3 AM.
Look east for the meteor shower.
The Geminid Meteor Shower is named after the Gemini constellation, which is in the east sky. The Gemini constellation outlines the shape of two twins in Greek Mythology.
Meteor showers are often named after a constellation, the constellation near where they appear.
