NASA Confirms 3I/ATLAS as Natural Interstellar Comet, Not Alien Spacecraft

It reveals an 11.2-kilometer nucleus on a hyperbolic orbit making a rare October 30 perihelion inside Mars’s path.

Overview

  • NASA scientists have dismissed artificial origin theories after observing typical cometary coma and gas emissions.
  • Follow-up studies indicate its nucleus measures roughly 11.2 kilometers across, making it the largest interstellar object observed so far.
  • Its hyperbolic trajectory carries it at about 221,000 km/h toward an October 30 perihelion at approximately 1.4 astronomical units from the Sun.
  • The comet will maintain a safe distance from Earth, never coming closer than 1.6 astronomical units, and is expected to remain visible until September and again after December.
  • As the third confirmed interstellar visitor, 3I/ATLAS presents a valuable opportunity to analyze pristine material expelled from another star system.
