Sleeping Bear Perseids, photo by Kenneth Snyder
Without question the best meteor shower of the summer in Michigan is the Perseids, EarthSky’s Everything you need to know about the Perseid Meteor Shower has (predictably) all kinds of details and diagrams to help you get the most out of this annual display. The most important thing is to start watching now as the August supermoon is full this weekend.
Every year, from around July 17 to August 24, our planet Earth crosses the orbital path of Comet Swift-Tuttle, the parent of the Perseid meteor shower. Debris from this comet litters the comet’s orbit, but we don’t really get into the thick of the comet rubble until after the first week of August. The bits and pieces from Comet Swift-Tuttle slam into the Earth’s upper atmosphere at some 210,000 kilometers (130,000 miles) per hour, lighting up the nighttime with fast-moving Perseid meteors. If our planet happens to pass through an unusually dense clump of meteoroids – comet rubble – we’ll see an elevated number of meteors.
…The swift-moving and often bright Perseid meteors frequently leave persistent trains – ionized gas trails lasting for a few moments after the meteor has already gone. Watch for these meteors to streak the nighttime in front of the age-old, lore-laden constellations from late night until dawn as we approach the second weekend in August. The Perseids should put out a few dozen meteors per hour in the wee hours of the mornings of August 11, 12 and 13.
