Comet 3I/ATLAS Is Accelerating. Here's What That Means
Summary
Comet 3I/ATLAS, an interstellar object passing through our solar system, is accelerating due to gas released from its surface as it nears the Sun. It will come closest to Earth on December 19 but poses no threat, remaining over 170 million miles away. First detected in July, this comet travels on a path that takes it beyond the Sun's gravity.Key Facts
