**["James Webb" accidentally discovered a very small asteroid while observing a larger asteroid](https://www.aanda.org/articles/aa/full_html/2023/02/aa45304-22/aa45304-22.html)** Scientists use infrared to study asteroids and learn about their physical and thermal properties and about the small objects in our solar system. But to do this, they need to know the orbit of the asteroid they're studying. With a new tool called JWST-MIRI, scientists will be able to detect many small asteroids that were previously unknown. This tool allows them to study these asteroids even if they don't know the exact location of the object. The scientists used this tool to study two asteroids and were able to learn more about their size, orbit, and other properties. They found that the first asteroid is about 14.5-16.5 kilometers wide and has a low brightness. The second asteroid is much smaller, only 100-230 meters wide, and is in the inner main belt region of the solar system. These observations will help scientists study the formation and evolution of asteroids and fill in the gaps in our knowledge of small objects in the solar system. @mr27.near, are you with us?
