A new interstellar object, A11pl3Z, has been discovered in our solar system, marking the third such object to be observed. It was first discovered zipping near the sun this fall.

The object, a celestial body from another star system, was discovered on Tuesday by the University of Hawaii’s Asteroid Terrestrial-impact Last Alert System, or ATLAS, team. At this point, it remains unclear what the object may be or look like as it moves near Jupiter.
