In the Know: Geminids meteor shower

MANILA, Philippines—Considered one of the best and reliable annual meteor showers, the Geminids can be seen from almost any point on Earth during mid-December each year.

These meteors are fast and bright, and tend to be yellow in color with an average rate of 120 meteors per hour at its peak.

It first appeared in the mid-1800s, but the first showers were unimpressive with a mere 10 to 20 shooting stars per hour.

Since then the Geminids have grown in intensity, making it one of the most spectacular annual showers.

The Geminids are the most massive of all the debris streams Earth passes through every year, according to Nasa astronomer Bill Cooke.

He called the Geminids the 900-lb “gorilla” of meteor showers with a velocity of 35 km per second.

But unlike most meteor showers that come from comets, the Geminids originated from an asteroid, the 3200 Phaethon. Researchers concluded that the Geminids were ejected dust as a result of breakdown of surface rocks whenever Phaethon nears the Sun.
