The population index of the Quadrantids meteor shower is 2. The population index refers to the magnitude distribution of the meteorites, the smaller the index, the brighter the meteors are, the higher, the dimmer the meteors are. For this particular meteor shower, faint meteors are more frequen...
Look skyward on the night of December 13 after 9P.M.for a chance to catch a glimpse of theGeminid meteors. The Geminid meteor shower is the most active shower of the year. This year, the peak of the meteor shower meets a waxing gibbous Moon, meaning that the sky will still be affec...

It also shields us against meteoroids, most of which burn up in the atmosphere and are visible asmeteorsin the night sky before striking the Earth as meteorites. MAGNETOSPHERE The fast spinning of our planet and its molten nickel-iron core generates a magnetic field, which is something the so...

Meteors between 1 and 20 metres (3 and 60 feet) in size enter the atmosphere every few weeks. One such notable event was the explosion of an 17-metre (56-foot) asteroid over Chelyabinsk, Russia, on February 15, 2013. About 1,500 people were injured, mostly by flying glass when the ...
