Friday several asteroids are zipping by Earth, tracked by NASA’s Jet Propulsion Laboratory (JPL).
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, each millennia leaving behind 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 it’s 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 over eleven kilometers across, and it caused the end of the Creataceous-Palogene era in a mass extinction event kiiling 75% of animal species.
The study comes as 9 asteroids are heading past Earth today, the closest one named 2015 EF7, measuring 115 feet to 257 feet in diameter and traveling at 7.08 kilometers per second. It misses Earth by just 4,824,989 miles, and will not return until Sunday Sep 01, 2019. The largest asteroid passing today is ‘2017 EV2’ which is travelling at 14 kilometers per second (30,680 mph) and measure 603 to 1,349 feet in diameter. Thankfully it is estimated to miss us by 34,834,740 miles this time around, but it will return in March 2020.
