International astronomers detected an asteroid roughly the size of Rome's Colosseum, between 300 and 650 feet in length.

The asteroid roughly the size of Rome’s Colosseum – between 300 and 650 feet (100 to 200 meters) in length – has been detected by an international team of European astronomers using NASA's James Webb Space Telescope.

"We – completely unexpectedly – detected a small asteroid in publicly available MIRI calibration observations," Thomas Müller, an astronomer at the Max Planck Institute for Extraterrestrial Physics in Germany, said in a statement.

In an analysis of this data, the team's results suggest the object measures 100–200 meters, occupies a very low-inclination orbit and was located in the inner main-belt region at the time of the Webb observations.

If confirmed as a new asteroid discovery, this detection would have implications for the understanding of the formation and evolution of the solar system.
