If you missed Halley's Comet, there is still a chance to catch a piece of the show this week when the Earth passes through the track of debris laid down by the passage of the comet over the millenia.
A meteor shower -- predicted to provide better than average viewing -- will be visible tonight and Monday night. The U.S. Naval Observatory said the best viewing should be tonight in the three hours after midnight when the moon is not up and the greatest number of meteors may be seen.
About 20 meteors per hour are expected, including some "fireballs," or meteors brighter than surrounding stars, the observatory said.
As Halley's Comet moves through its long, elliptic orbit over 76 years, it lays down a track of debris, made up mainly of rocks or metallic materials blown off the comet at some time during its 4 billion of years of circling the sun.
The bits of Halley debris that will become meteors are mostly pebble-sized grains and will be traveling at 40 miles per second when they hit the Earth's atmosphere. Some fall to the ground, and some are burned up as they streak brightly through the atmosphere.
The best viewing will be away from city lights.
