Radar Catches Oddly Shaped Stadium-Sized Asteroid Zooming Past Earth

The perchance hazardous asteroid 2024 ON looks similar an adorable abstraction peanut oregon a chunky snowman tumbling its mode done the star strategy successful caller close-up images of the past abstraction rock.

The Deep Space Network’s Goldstone Solar System Radar adjacent Barstow, California, captured a bid of radar images of the near-Earth asteroid a time earlier its adjacent attack to our planet. The close-up views of asteroid 2024 ON suggest it’s apt a interaction binary, with 2 rounded lobes, 1 astir treble the size of the other, separated by a constrictive neck, according to NASA.

2024 ON flew past Earth astatine an eerily adjacent region of 620,000 miles (1 cardinal kilometers) connected September 17. Through the radar images, NASA was capable to find a much close measurement of the asteroid, which stretches astir 1150 feet (350 meters) long. The radar images besides revealed agleam spots, apt indicating the beingness of ample boulders connected the aboveground of the asteroid.

Contact binaries are reasonably communal successful the star system; astir 14% of near-Earth asteroids larger than 660 feet (200 meters) stock the aforesaid awkward-looking peanut shape, according to NASA. It’s imaginable that these abstraction rocks were erstwhile 2 asteroids that came excessively adjacent to 1 another, becoming locked unneurotic successful a gravitational creation and drafting nearer until they fused unneurotic arsenic 1 body.

In November 2023, it was revealed that the asteroid Selam, a tiny moonlet orbiting astir the larger Dinkinesh asteroid, is simply a interaction binary aft NASA’s Lucy spacecraft carried retired its archetypal adjacent flyby of the unusual trio. If a spacecraft isn’t disposable for a flyby, past radar imagery is the main method astronomers usage to uncover interaction binaries.

Although it’s classified arsenic a perchance hazardous asteroid, 2024 ON does not airs a menace to Earth successful the foreseeable future. NASA dubs immoderate abstraction stone that comes wrong 4.65 cardinal miles (7.5 cardinal kilometers) of Earth arsenic perchance hazardous, adjacent if determination is nary contiguous menace of it colliding with our planet.

Still, NASA needs to support a adjacent oculus connected these flying abstraction rocks successful lawsuit immoderate flimsy accommodation to their trajectories puts them connected a collision people towards Earth. The caller measurements obtained by the radar images “have allowed scientists to greatly trim the uncertainties successful the asteroid’s region from Earth and successful its aboriginal question for galore decades,” NASA wrote successful a statement.

The past clip 2024 ON made a adjacent attack to Earth was successful 2013, and it is scheduled for different rendezvous with our satellite successful 2035. Scientists hold for these flybys to marque close measurements of abstraction rocks, and to get a person look astatine their sometimes awkward-looking shapes.
