In other words, the 250 meter-wide piece of space rock has gone from an unlikely 0.003% chance to a vanishingly small 0.0004% chance of hitting Earth. Would you be comfortable with putting money on either one of those odds? I know I wouldn't, but there has been some low-key concern that the near-Earth asteroid (or NEO for short) could be a potential doomsday asteroid, slamming into Earth in 27 years time. But fear not, the chances of that happening has shrunk, by a whole order of magnitude.
This announcement comes from Puerto Rico during a meeting of the American Astronomical Society's Division for Planetary Sciences, where Dave Tholen and collaborators from the University of Hawai'i presented their refined measurements of the asteroid's path through the Solar System, even after the NEO passes Earth in 2029 (at a distance of 18,400 miles or 30,000 km).
"Apophis has been one of those celestial bodies that has captured the public's interest since it ...
