Webb Finds Extremely Small Main Belt Asteroid

A serendipitous discovery demonstrates the capacity of the James Webb Telescope to do science on a small scale.

Webb detects extremely small main-belt asteroid

A previously unknown 100-to-200-meter asteroid—roughly the size of Rome's Colosseum—has been detected by an international team of European astronomers using the NASA/ESA/CSA James Webb Space Telescope. Their project used data from the calibration of the Mid-InfraRed Instrument (MIRI), in which the team serendipitously detected an interloping asteroid.
