An interstellar visitor is making its closest approach to our star, and while Earth-bound observers can't get a clear view, our robotic emissaries in space are perfectly positioned to witness the event. Comet 3I/ATLAS, an object hailing from beyond our solar system, is set to reach perihelion—its closest point to the Sun—on October 30. At this point, it will be approximately 125 million miles from the Sun, marking its most active phase as solar radiation intensifies.
