A little over 10 Earth radii. That is very close for something this size, compared to other near misses trumpeted as “close”.

- Someone 7y agoScaringly close. 70,000 km is only 11 times the radius of the earth. That means a rock that size thrown at random that does get that close or closer to earth has a probability of a collision course with earth of about 1 in 11² ~= 0.8%. Being on collision course doesn’t imply it will impact, as it may explode in the atmosphere (probability? I wouldn’t know) or bounce of it (probability effectively zero, I would say/guess)
