There香蕉视频直播檚 a 香蕉视频直播渕ust-see香蕉视频直播 celestial event set to take place next week, that is, if it香蕉视频直播檚 even possible to observe it.
The Geminid meteor shower is to produce a consistent 120 meteors per hour in the night sky Dec. 13-14. The Geminids occur every year at the same time, but a key challenge with observing the 香蕉视频直播榝alling stars香蕉视频直播 is whether or not clouds obstruct the view.
Astronomy educator and Royal Astronomical Society of Canada columnist Gary Boyle explained that meteor showers occur at the same time every year because they are usually produced by a comet that rounds the sun.
香蕉视频直播淢aterial is blown off the comet when it comes close to the sun just by the solar radiation,香蕉视频直播 Boyle said. 香蕉视频直播淓very year when we do our lap around the sun, just like a car goes around a circular racetrack, we encounter this debris.香蕉视频直播

The Geminids are not caused by a comet, but rather by debris from an 5.8km in diameter asteroid named 3200 Phaethon.
Skipping across the Earth香蕉视频直播檚 atmosphere at 36km per second, Boyle said the Geminid meteor shower is particularly good for stargazers because they are 香蕉视频直播渟low, graceful, bright meteors.香蕉视频直播
香蕉视频直播淚t香蕉视频直播檚 something that people will remember for the rest of their lives. Nature always has a way of bringing calm and relaxation to no matter what it is,香蕉视频直播 Boyle said.
Boyle said the meteors are called 香蕉视频直播渆arth grazers香蕉视频直播 because they don香蕉视频直播檛 actually enter the atmosphere.

If the skies are clear, the other competing force to observing the shower is light pollution from cities and the moon. The moon is to be about 77 per cent lit that evening. Still, Boyle said, Canadians should be able to see some of the brighter meteors.
The best time to observe, Boyle said, is at about 12 a.m. on Dec. 14.
