2015 Geminids meteor shower

In 2015, the Geminids will peak between December 13 and 14. A waxing crescent Moon (Moon's phase after a new Moon) will create good conditions for viewing the shower.

Northern Hemisphere observers should try their luck right after sunset on December 13, while those in the Southern Hemisphere should try to catch the shower after midnight on December 14.

The Geminids can be annually observed between December 4 and December 17, with its peak activity being around December 14. The shower owes its name to the constellation Gemini from where the meteors seem to emerge from in the sky.

An Asteroid Meteor Shower

Unlike most other meteor showers, the Geminids are associated not with a comet but with an asteroid - the 3200 Phaethon. The asteroid takes about 1.4 years to orbit around the Sun.

The Geminids are considered to be one of the more spectacular meteor shower during a year, with the possibility of sighting around 120 meteors per hour at its peak.

Where to view the Geminids

The Geminids can be observed from locations all around the world.

While it is not necessary to look in a particular direction to enjoy a meteor shower – just lie down on the ground and look directly above and you are bound to see some meteors – astronomers suggest looking towards the south to view the Geminids.

When to view the Geminids

The best time to view the Geminids between sunset, local time and before sunrise.

• 八月中等過一次流星雨。整個天文愛好者協會的人都在沒有燈光的田野裏等到淩晨。現在這個季節，估計沒人半夜在外麵等了。 -香草仙子- ♀ (0 bytes) () 12/15/2015 postreply 14:42:19
