Earth, asteroid

Skyscraper-sized asteroid and 4 others speed past Earth on the same day
Four huge asteroids — and a fifth that's much smaller — are passing Earth on Thursday in their closest approaches to the planet ever recorded.
4 large asteroids, including a skyscraper-size 'city killer,' will zoom past Earth in a 12-hour span tomorrow (Oct. 24)
Four "potentially hazardous" space rocks, which are between 100 and 580 feet across, will all make their closest approaches to Earth within less than 12 hours of one another on Thursday (Oct. 24). Two of them were only discovered earlier this month.
Big asteroid quartet, including 'city killer,' to approach Earth
Four enormous asteroids, including one with the potential to wipe out an entire city off the map, are making a close flyby of Earth on Thursday. Deemed potentially hazardous, each will come within 30 miles of our planet in just a span of 12 hours.
'City killer' asteroid is one of four making close approach to Earth
Four huge asteroids, including one the size of a skyscraper, are making a close approach to planet Earth. Asteroids striking the Earth can have a devastating impact, but luckily, experts are able to gauge whether those heading in our direction pose an imminent threat.
‘City killer’ asteroid is one of 4 to graze Earth’s orbit today
NASA has announced that an airplane-sized “city killer” asteroid will skim past Earth today — one of four “hazardous” space rocks to graze our orbit in less than 12 hours. Dubbed 2002 NV16, the cosmic boulder is slated to pass within a minimum distance of 2.
