2008 DB is a near-Earth asteroid that zipped past our planet in 2008 and hasn't been seen since. Due to the brevity of this encounter, astronomers have limited information about this celestial visitor.
Discovered in February 2008, 2008 DB's estimated size falls between 28 and 62 feet (8.5 and 19 meters) in diameter. That's roughly the size of a school bus, making it a relatively small near-Earth object. Unfortunately, due to the short observation window, scientists weren't able to determine its precise orbit or predict its future trajectory.
While 2008 DB is no longer a threat, it serves as a reminder of the vast number of asteroids that share our cosmic neighborhood. Many near-Earth objects are difficult to detect, and some may pay us surprise visits. Thankfully, astronomers are constantly scanning the skies for potential hazards, and our ability to track and understand these objects is constantly improving.
Here's a quick summary of 2008 DB:
