Two airplane-sized asteroids passed close to Earth on June 9, 2026 [1].
NASA and other astronomers monitor these near-Earth objects to assess potential impact threats and improve the global capabilities of space surveillance. Tracking such events allows scientists to better understand the trajectory of celestial bodies that enter the planet's vicinity.
The objects, designated as 2026 LD and 2026 KM3 [2], are described as being roughly the size of an airplane [1]. According to reports, the two asteroids were tracked as they passed the planet at distances measured in millions of kilometres [2].
"Astronomers are tracking two near‑Earth asteroids that will make relatively close approaches to our planet on June 9," MSN Science staff said [1].
While the approach is described as relatively close in astronomical terms, the distance of millions of kilometres ensures the objects do not pose an immediate risk to the planet [2]. The tracking of 2026 LD and 2026 KM3 is part of a broader effort to map the movements of near-Earth objects.
"Earth objects, 2026 LD and 2026 KM3, are being tracked as they pass Earth at distances measured in millions of kilometres," MSN Tech & Science staff said [2].
These observations provide critical data for planetary defense systems. By calculating the precise orbit of these airplane-sized rocks, NASA can refine its models for future close-approach events, a necessity for long-term planetary safety.

The monitoring of 2026 LD and 2026 KM3 highlights the ongoing effort to catalog near-Earth objects. While these specific asteroids posed no threat, the ability to detect and track objects of this size is essential for developing early warning systems and planetary defense strategies against potentially hazardous asteroids.
