Meteor is captured in video in Wisconsin streaking across the sky

A meteor in Wisconsin was seen streaking across the sky from west to east about 10 p.m. Wednesday. Anyone who saw it instantly overwhelmed the emergency response phone lines saying they saw a blue/yellow fireball tracking from northwest to southeast. A meteorologist with the National Weather Service said the meteor exploded over Iowa County in southwest Wisconsin at about 24,000 feet, showering meteorites, beginning some forest fires. Those who saw it reported a window-rattling sonic boom.

Wisconsin meteor data wanted

If you had the opportunity to see the meteor in Wisconsin, the International Meteor Organization would like to hear from you. Data about where the meteor in Wisconsin may have landed is a pay day for The International Meteor Organization to help scientists discover any possible meteorites. Any details given will help scientists track the orbit of the meteor and link it to either asteroids or comets.

Video of Meteor in Wisconsin

The meteor was a natural object that originate in space. Friction caused it to superheat into a brightly glowing fireball captured on video after it entered the atmosphere. Those pieces of the meteor in Wisconsin that really hit the Earth will now be called "meteorites." As of February 2010, about 1,086 meteorites are found after witnesses reported them as meteors. Over 38,000 meteorites are found. Meteorites were found on the moon by Apollo astronauts also.

Was the meteor in Wisconsin turned into a meteorite?

Although bigger than most meteors, the meteor in Wisconsin wasn't unique. The American Meteor Society Fireball Sightings Log: 2010 shows almost daily reports of meteor sightings around the country. On the other hand, meteorite discoveries are rare. On Jan. 22, 2010, a meteorite struck the office building of Dr. Frank Ciampi in Lorton, VA. The meteorite put a hole within the roof and ripped up the floor 10 feet from where Ciampi was working. Fragments of meteor about the size of a tennis ball were strewn about the room. Damage was light, and he probably doesn’t need a loan to fix it.

Unlikely for meteor in Wisconsin

According to astronomer Alan Harris on wikianswers.com, the chances of being hit and killed by a meteorite in a person’s lifetime are about the exact same as Bill Gates needing a payday installment loans: 1 in 700,000." As a comparison,” he said, “you’re more likely to die in a fireworks accident; But what’s funny is, this is a slightly higher chance than being killed by a terrorist!” The last impact on a human was in 1954, when Elaine Hodges of Sylacauga, Ala., was struck within the hip when napping on her couch. There is a Life magazine image of her showing the injury.

It wasn't the first meteor in Wisconsin

This meteor hitting Wisconsin wasn't the first to impact the state. Scientists, years ago saw something different about rocks around Wavery, Wis., and concluded an ancient catastrophic event occurred reports Space.com. They believe a 650- to 700-foot meteorite crashed into the earth at speeds up to 67,500 mph. The impact 450 million years ago released a lot more than 1,000 megatons of explosive energy, blasting a massive hole in a 4-mile area called Rock Elm about 70 miles east of Minneapolis, three scientists said in an article published in the Geological Society of The US Bulletin. Over a long time, dirt, shale, and sediment filled the hole. Wisconsin had a shallow sea covering it at the time, blunting the impact. In the world, there are around 200 meteorite impact sites known. The US only has a couple dozen of them. Scientists suggest that they occur only each few hundred thousand years, and only a couple dozen in the US. They are believed to have occurred only each ! and every few hundred thousand years.
