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 discovery of an extraterrestrial visitor.
  • Analysis shows the interstellar object 3I/ATLAS travels at over 60 km/s on a hyperbolic path, confirming its origin outside the solar system, ESA's trajectory analysis indicates.
  • Astronomers confirmed the interstellar origin of 3I/ATLAS, traveling at over 60 km/s with an estimated 10 km diameter and a faint coma, based on observations from July 1-2.
  • NASA states the interstellar object will stay over 150 million miles from Earth, passing inside Mars’ orbit later this year and observable through September and December.
  • Discovery of the third interstellar object, 3I/ATLAS, on July 1 by Chile's ATLAS survey, offers new scientific opportunities with upcoming observatories like Vera C. Rubin to learn about extrasolar material.
