Radar Images Show Large Object Drifting Past Earth

The scale is astonishing.

Tall Boy

A near-Earth asteroid is popping heads for a definite form that makes it awfully onerous to take severely — though it is “probably hazardous.” As seen in a sequence of radar pictures, the rocky object seems to be a complete lot like an unlimited peanut tumbling by area. Or, relying on the way you see it, maybe a decapitated snowman.

The thing, often called 2024 ON, got here inside 621,000 miles of Earth when it blew previous our planet on September 16, according to NASA’s Jet Propulsion Laboratory. That is about 2.6 occasions the gap to the Moon, bringing it shut, however not uncomfortably so.

First picked up in July by the Asteroid Terrestrial-impact Final Alert System (ATLAS) in Hawaii, the nutty invader can also be formidably giant. Its width is unclear, however lengthwise, it is an astonishing 1,150 ft throughout. If it had been a skyscraper, it might be practically as tall because the Empire State Constructing.

Ugly Twosome

Taken only a day earlier than the asteroid made its shut method with our planet, the radar pictures — organized in an animation here — had been captured by the Deep House Community’s Goldstone Photo voltaic System Radar close to Barstow, California.

Due to their element, we now know what the asteroid owes its peanut form to. It is really what’s often called a contact binary: two smaller objects which might be touching one another to kind an obvious bigger construction.

On this case, one of many rounded lobes is about 50 p.c bigger than the opposite, linked by a definite “neck,” NASA stated. In accordance with the area company, at the least 14 p.c of asteroids of this measurement — 660 ft and longer — seem like contact binaries.

The radar imagery additionally reveals the presence of distinct options on the asteroid’s floor, together with boulders that present up as brilliant spots.

Protected in House

That is really the second peanut-shaped asteroid to swing by our planet previously month or so. A contact binary of comparable measurement, 2024 JV33, made an in depth method on August 18, demonstrating an elongated orbit resembling that of a comet influenced by Jupiter.

Thankfully, neither of those nutjobs ought to trigger us any hurt.

“This asteroid is assessed as probably hazardous, however it doesn’t pose a hazard to Earth for the foreseeable future,” NASA stated. “These Goldstone measurements have allowed scientists to enormously cut back the uncertainties within the asteroid’s distance from Earth and in its future movement for a lot of many years.”
