644-Tracking Meteoriods
Published 4 years, 9 months ago
Description
A team of astronomers find that as many as 14 comets which came to less than 4 times the Moon's distance from us as long as 4,000 years ago are detectable as meteor showers in the present era. These results make us aware of potentially hazardous comets from the past which could come into our space again in the future.
