NASAscientists have released enchanting images of anasteroidthat zipped past Earth this week — revealing it to be the shape of a uncanny tumbling snowman .
The asteroid , named 2024 ON , flewsafely past our planetat a distance of 620,000 stat mi ( 1 million kilometers ) — about 2.6 clip the length between the moon and Earth — on Tuesday ( Sept. 17 ) . It was traveling at 19,842 miles per hour ( 31,933 km / h ) , or around 26 times the speeding of sound .
The “potentially hazardous” asteroid 2024 ON looks like a tipsy cosmic snowman in these radar images obtained by the Deep Space Network’s Goldstone Solar System Radar.
The unexampled prototype were captured by the GoldstoneSolar SystemRadar near Barstow , California on Sept. 16 . They showed that the skyscraper - size asteroid resemble something like a peanut . That ’s because 2024 ON is actually two asteroid that became engage by their own gravity into a formation be intimate as a contact binary star after they come too near to each other . Other notable contact lens binary program includeSelam , a two-fold - lobed ' moonlet’orbiting the asteroid Dinkinesh in the master belt ammunition between Mars and Jupiter , andArrokoth , a glacial object beyond the sphere of Pluto that was hit the books by NASA ’s New Horizons investigation in 2015 .
" This asteroid is sort out as potentially wild , but it does not bewilder a hazard to Earth for the foreseeable future , " NASAwrote in a statement . " These Goldstone measurements have allowed scientist to greatly slenderize the doubt in the asteroid ’s aloofness from Earth and in its next movement for many decades . "

NASA deems any outer space object that comes within 4.65 million mile ( 7.5 million km ) of our planet as " potentially wild , " even if they pose no quick terror to Earth . That ’s because even slight nudge to such an asteroid ’s trajectory — say , by bump into another asteroid — could commit it onto a hit grade with Earth .
NASA tracks the locations and orbits of about 28,000 asteroid by scanning the intact Nox sky every 24 hours . The blank space agency has estimated the flight of all these near - Earth objects beyond the end of the century , and found that Earth face no sleep with risk from an apocalyptical asteroid hit for at least the next 100 years .
