A skyscraper-size, "potentially hazardous" asteroid is set to make a close approach to Earth this week — and you can see it zoom past for yourself, either by using a backyard telescope or via a free online livestream.
The asteroid, which was discovered earlier this year, was initially predicted to have a slim chance of hitting our planet in 2089 — temporarily earning it a spot at the top of the European Space Agency’s (ESA’s) impact risk list. But, following new observations, it is no longer considered an imminent threat.
