“Boomerang” asteroid passing Earth for the seventy-fourth time since 1900.
An asteroid named ‘478784 (2012 UV136)’ is on course to pass by earth 110 times in the next 100 years. After passing Earth today it will return next time in May 2020. NASA will continue to monitor it’s path carefully.
The first time asteroid ‘478784 (2012 UV136)’ was detected was on Oct 22, 2012. Since 1900 it has passed Earth 74 times and we can expect it to return one hundred and ten more times within the next 100 years.
478784 (2012 UV136) measures 69 foot to 155 foot in diameter and will pass by Earth at a distance of 6,861,634 miles.
Fun Fact: If this asteroid was a member of a frequent flyer club, it would amass 137,187 frequent flier miles per day.
The solar system has been a violent place ever since the Sun formed 4.6 billion years ago. 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 plates movements.
NASA Researchers 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 measured a full 11 to 81 kilometers across, and it caused the end of the Creataceous-Palogene era in a mass extinction event kiiling 75% of animal species.
