Research team identifies 138 previously unknown space rocks as small as 10 meters in the main asteroid belt. An international research team led by MIT physicists has identified the smallest asteroids ever observed in the main asteroid belt between Mars and Jupiter. The discovery includes 138 new “decameter” asteroids, ranging from bus-sized (10 meters) to stadium-sized objects. The detection represents a change from previous observations, which could only identify asteroids approximately one kilometer in diameter. Using data from NASA’s James Webb Space Telescope (JWST), the team processed over 10,000 images originally captured for studying the TRAPPIST-1 planetary system. “We have … Continue reading MIT Astronomers Detect 138 Smallest Main Belt Asteroids, Some as Small as 10 Meters
