This means it has two rounded lobes, separated by a distinct neck, with one lobe about 50% larger. <\/p>\n<p>Radar images have revealed that 2024 ON measures approximately 350 m (1 150 feet) in length, with surface features as small as 3.75 m (12.3 feet) visible.<\/p>\n<p>Bright radar spots observed on the surface are likely large boulders. The images capture about 90% of the asteroid\u2019s rotation, which takes approximately six hours.<\/p>\n<p>The radar images were captured just a day before the asteroid made its closest approach.\u00a0<\/p>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><figcaption class=\"wp-element-caption\">Image credit: NASA\/JPL<\/figcaption><\/figure>\n<\/div>\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\">\n<p>\n<iframe loading=\"lazy\" title=\"Radar images of asteroid 2024 ON during close approach to Earth on September 17\" width=\"1110\" height=\"624\" src=\"https:\/\/www.youtube.com\/embed\/55utSMVQiuE?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/p>\n<\/figure>\n<p>NASA is constantly monitoring near-Earth objects such as 2024 ON to determine any potential risks they may pose.
