Interstellar Comet 3I/Atlas Enters Inner Solar System

  • On July 1, the ATLAS Survey in Chile detected the third interstellar object, designated 3I/ATLAS, marking a rare cosmic visitor from beyond our solar system.
  • Analysis shows 3I/ATLAS follows a hyperbolic path from outside the Solar System, traveling over 60 km/s, confirming its interstellar origin, according to ESA's trajectory analysis.
  • NASA's tracking shows 3I/ATLAS about 420 million miles away, traveling at over 60 km/s with a roughly 10 km diameter and faint coma.
  • NASA confirms 3I/ATLAS will stay over 150 million miles from Earth, pass inside Mars’ orbit later this year, and remain visible through September and December.
  • Scientists anticipate that studying 3I/ATLAS will reveal details about interstellar material, with Vera C. Rubin Observatory expected to increase detection rates of such objects in coming years.
