Large 502 ft to 1,122 ft diameter asteroid passing Earth
Today the large asteroid ‘(2019 AW4)’ is zipping past Earth, thankfully missing by 6,495,369 miles.
The first time asteroid ‘(2019 AW4)’ was detected was on Dec 15, 2018. Since 1931 it has passed Earth 8 times and we can expect it to return thirty more times within the next 100 years.
(2019 AW4) is foot to foot in diameter and is passing by Earth at a distance of miles.
NASA has marked this asteroid as potentially hazardous, which means is has a significant size and will pass periously close to Earth in the future. Most asteroids will eventually be cleared as more data is gathered about their orbits.
Fun Fact: If this asteroid was a member of a frequent flyer club, it would amass 951,263 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, or 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 been a full up to eighty-one kilometers across, and causing the end of the Creataceous-Palogene era in a mass extinction event kiiling 75% of animal species.
