741 Foot Diameter Asteroid Passing Near Earth
The asteroid ‘(2017 ET22)’ was first spotted on Mar 06, 2017. Since 2015 it has passed Earth 8 times and we can expect it to return two more times within the next 100 years.
(2017 ET22) measures 332 foot to 741 foot in diameter and is passing by Earth at a distance of 29,059,227 miles.
Fun Fact: If this asteroid was a member of a frequent flyer club, it would amass 805,570 frequent flier miles per day.
Ever since the Sun formed 4.6 billion years ago, the solar system has been a violent neighbourghood. Our little neck of the woods in space was once littered with meteors, comets and debris all crashing into each others and our planets, all the time leaving impact craters. On Earth, these craters have been covered up or destroyed due to erosion, weather, and tectonic plate movements.
Researchers from NASA have now used data from a Moon probe and found that 290 million years ago the rate of impacts increased dramatically and that this is still ongoing.
Just one major impact with Earth could cause extinctions like the one that ended the dinosaurs 66 million years ago and created the Chicxulub crater in Mexico. That asteroid is estimated to have been a full up to eighty-one kilometers across, and it caused the end of the Creataceous-Palogene era in a mass extinction event kiiling 75% of animal species.
