The Geminids — the year's best, last and least talked about multicolored meteor shower — has started and could see up to 150 "shooting stars" in an hour in December.

The Geminid meteor shower begins Tuesday as one of the year's best meteor showers. The Geminids start in mid-November and run through Christmas Eve. Peak activity happens Dec. 13 and 14, when 120 meteors per hour are possible under the right conditions.

Leonid meteors are visible in the night sky from early November to early December. This weekend, the ongoing meteor shower reaches its maximum intensity, with a peak Sunday night into early Monday.

Meteors during the Leonid shower are considered to be some of the fastest to appear each year, NASA said, as they travel at about 44 miles per second across the night sky, and they are known for their fireballs—caused by larger debris—that are often brighter and leave behind “long and colorful tails.”

The Leonid meteor shower has been active all month, but it will be at its strongest Saturday and Sunday nights, according to the American Meteor Society. The shower is best viewed between midnight and dawn, ideally in a place well away from city and street lights.

Stargazers in Pennsylvania are in for a celestial treat as the Leonid meteor shower lights up the night sky, EarthSky reports. The annual meteor display is expected to peak late tonight, Saturday, Nov.
