Aside from preparing your Christmas presents and gearing up for get-togethers, another exciting thing to do this December is to watch the skies—not to wait for Santa and his reindeer, but to witness the spectacular meteors!

Meteoroids VS Meteors & Meteorites
Meteoroids are small rocks or particles orbiting around the sun. Once a meteoroid enters the Earth’s atmosphere, it vaporizes and becomes a meteor, also known as a “shooting star” or bulalakaw in Tagalog.
According to the National Aeronautics and Space Administration (NASA), as this space rock falls toward the Earth, the air resistance or drag makes it extremely hot. So what we see is not actually the rock, but the bright streak or the glowing hot air as it approaches the atmosphere.

If a small asteroid or large meteoroid survives its entry or passage through the atmosphere and lands on the surface of the Earth, it is called a meteorite.

December is an ideal month for astronomy enthusiasts as the Geminids Meteor Shower lights up the sky from December 4 to 17, 2015. Appearing to come from the constellation of Gemini, Geminids meteors do not originate from a comet, but from an asteroid. Meteors from this shower are very rocky and are more visible.

NASA explains that these meteors originated from the Asteroid 3200 Phaethon, which takes 1.4 years to orbit the sun. Phaethon is a small asteroid with a diameter of 5.10 kilometers.

Dubbed as a “dead comet”, the Phaethon does not develop a cometary tail when it passes by the sun. Its spectra look like a rocky asteroid instead.

3200 Phaethon was discovered by the Infrared Astronomial Satellite on October 11, 1983. Due to its close distance to the sun, Phaethon is named after the character in Greek mythology that drove the chariot of Helios (the God of Sun). But it was the astronomer, Fred Whipple, who recognized that the Geminids meteor shower originated from Phaethon.

The Geminids is considered as one of the best and most reliable annual meteor showers. So mark your calendars now! Its peak activity is on the late night of December 14 until the early morning hours of December 15. PAGASA says that if good weather permits, an observer can witness around 40 meteors per hour.

Viewing Tips
– Get as far away from urban pollution as possible. Find a location with a clear or almost cloudless night sky.
– Search for the darkest patch of sky.
– Clothing matters! Wear clothes that suit cold overnight weather.
– Bring something comfortable for you to sit or lie down.
– It takes time, so be patient.
– Put away the telescope or binoculars, which may reduce the amount of sky you can see at once.
– Relax your eyes. Do not look at any specific spot.
– Avoid looking at your gadgets or any other light source which could disturb night vision.
– If you have to look at something on the surface of the Earth, use a red light.
