747-sized asteroid skimmed by Earth, and scientists didn't see it coming (jpost.com) 5 points by runawaybottle 4y ago ↗ HN
[–] runawaybottle 4y ago ↗ Would an asteroid of this size have burned up if it entered our atmosphere?I thought we had asteroid detection figured out. [–] nightfly 4y ago ↗ https://en.wikipedia.org/wiki/Air_burst [–] [deleted] 4y ago ↗ (comment deleted) [–] breckenedge 4y ago ↗ It was coming at us from the direction of the sun at 85,748 km/h. Didn’t even see it until it had passed us. About 3x the size of the one that hit Russia, so probably would have been a pretty big whack. [–] runawaybottle 4y ago ↗ So what else is coming at us from the direction of the sun? [–] Arnt 4y ago ↗ Almost everything.Seriously. The Sun supplies us with a steady and strong stream of particles. [–] raxxorrax 4y ago ↗ It wouldn't be catastrophic:http://down2earth.eu/impact_calculator/input.html?lang=enBut we haven't figured out detection, we have about 1% chance to detect a larger one currently, depending on several parameters.
