UN-Backed Network Begins Two-Month Drill to Track Interstellar Comet 3I/ATLAS

Officials say the object poses no risk, serving as a real-world test of planetary defense coordination.

Overview

  • The International Asteroid Warning Network opened a November 27–January 27 observing window to practice tracking techniques on the active interstellar visitor.
  • NASA reiterated the scientific consensus that 3I/ATLAS is a natural comet, with senior official Amit Kshatriya stating it poses no threat to Earth.
  • The comet’s closest approach to Earth is scheduled for December 19 at roughly 1.8 astronomical units, distant enough for safety yet accessible to small telescopes.
  • ESA confirmed JUICE observed the object from November 2–25 with multiple instruments, with data return expected around February 2026 due to thermal and communications constraints.
  • New amateur images highlight a coma, greenish glow, and a long sunward “anti-tail,” stoking public interest as a few commentators advance unproven artificial-origin claims disputed by agencies.
