NASA captured a uncommon occasion as two asteroids, dubbed “planet killers” by scientists, got here very near Earth final week.
Scientists at NASA’s Jet Propulsion Laboratory (JPL) in Southern California tracked the 2 area rocks utilizing the Goldstone Photo voltaic System Radar and measured the objects’ dimensions.

JPL scientists tracked two asteroids that not too long ago flew safely previous Earth and used the Deep House Community to seize photographs, together with this picture of asteroid 2024 MK.
Asteroid 2024 MK, first found by scientists 13 days earlier than its closest strategy to Earth, was photographed Saturday as a 500-foot-long object.
Asteroid 2011 UL21, an object a couple of mile extensive that was noticed flying previous Earth at 58,000 mph on Thursday, was discovered to have a small moon orbiting about two miles from its floor.
Not one of the NEOs are susceptible to impacting Earth, however radar observations made through the two shut approaches will present useful coaching for planetary defenses, in addition to details about their dimension, orbit, rotation, floor particulars and details about their composition. clue data.
Asteroid 2011 UL21 will cross Earth on June 27 at a distance of 4.1 million miles (6.6 million kilometers), about 17 instances the space between the Moon and Earth, as detected by the Catalina Sky Survey in Tucson, Arizona, in 2011 System discovery.
Whereas the roughly one-mile-wide (1.5 kilometers) object is classed as “probably hazardous,” calculations of its future orbit recommend it is not going to pose a risk to our planet within the foreseeable future.
Scientists on the Jet Propulsion Laboratory used the Deep House Community’s 230-foot (70 m) Goldstone Photo voltaic System Radar (DSS-14) close to Barstow, California, to ship radio waves to the asteroid and use the identical antenna to obtain the mirrored alerts. .
Along with figuring out that the asteroid is roughly spherical, in addition they found that it’s a binary star system: a smaller asteroid or moon orbiting it at a distance of about 1.9 miles (3 kilometers).
“About two-thirds of asteroids of this dimension are considered binary methods, and their discovery is especially necessary as a result of we are able to use measurements of their relative positions to estimate their orbits, lots and mutual densities, which might present details about their key message of the way it shaped,” stated Lance Benner, chief scientist on the Jet Propulsion Laboratory, who helped lead the observations.
