NASA Sets Nov. 19 Briefing to Unveil 3I/ATLAS Images

International teams report a hyperbolic, no‑threat path with a distant Earth flyby in December.

Overview

  • NASA will stream a live briefing at 3 p.m. EST on Nov. 19 from Goddard to present multi‑mission images of interstellar comet 3I/ATLAS on NASA+, the agency website, YouTube and Amazon Prime.
  • Refined solutions using ESA’s ExoMars TGO data and NASA’s JPL/HORIZONS confirm no risk to Earth, with closest approach on or about Dec. 19 at roughly 1.8 AU (about 270–273 million km).
  • Trajectory forecasts show a Jupiter pass on March 16, 2026 at about 0.36 AU before the object continues on a hyperbolic course back into interstellar space.
  • The comet passed roughly 30 million km from Mars in early October, providing the closest spacecraft vantage yet for an interstellar visitor.
  • Observations indicate strong post‑perihelion activity, Hubble imaging reveals a tear‑shaped dust envelope, preliminary reports note elevated CO₂ relative to H₂O, and ESA’s JUICE observations are expected to be released around February 2026.
