🚨: 3I/ATLAS could help protect Earth from dangerous asteroids.
A newly found interstellar comet poses absolutely no threat to Earth, but a NASA-coordinated group plans to observe it to help our ability to monitor any future objects that might prove to be hazardous.

The project will serve as a training ground to not only predict the orbit of 3I/ATLAS, but to perform astrometric measurements (meaning, tracking the comet's speed and motion in Earth's sky, relative to objects like stars.) This will be used to inform future observations of comets or asteroids that may be a threat to Earth.
