2010 RF12 is a near-Earth asteroid that wasn't spotted until it made a surprise close approach to Earth in September 2010. Thankfully, it passed by safely, but this unexpected visit highlighted the importance of continuous sky surveys for near-Earth objects (NEOs).
Despite the late detection, astronomers were able to determine some key facts about 2010 RF12. It is estimated to be between 33 and 76 feet (10 and 23 meters) in diameter, roughly the size of a house. While not a giant space rock, it serves as a reminder that even smaller NEOs can be difficult to track.
The good news is that 2010 RF12 is now part of the catalogued NEOs. Since its close encounter, scientists have been able to refine its orbit and predict its future trajectory. Based on current calculations, there's no danger of it impacting Earth for the foreseeable future.
Here's a quick look at 2010 RF12:
The case of 2010 RF12 highlights the ongoing efforts in NEO detection. Astronomers are constantly searching the skies for potential hazards, and our ability to identify and track these objects is steadily improving. This not only helps us understand our cosmic neighborhood but also ensures we can be prepared for any potential future encounters.
