AN ASTERIOD NEARLY HITS EARTH?!
A Brazilian SONEAR Survey picked up an asteroid which almost hit earth! Apparently, the asteroid was 330 ft (100m) in width and passed within 43,500 miles (70,000 km) of earth. The asteroid's presence was only announced HOURS before it was supposed to come into contact with the earth.
Astronomers discovered this shocking moment by taking a sequences of images and looking for objects that move from image to image, that movement being the asteroid. Using this, it's helped them discover many more asteroids. They recorded a total of 2,000 asteroids that almost hit earth in 2017 alone.
So there you have it. We almost got hit by an asteroid and we didn't know about it. Shocking.
