You can see interstellar comet 3I/ATLAS now and over the coming months, but only with a telescope, not with the naked eye.

What 3I/ATLAS is

  • 3I/ATLAS is the third known interstellar object, confirmed in mid‑2025 after its unusual speed and trajectory showed it came from outside our solar system.
  • It follows a hyperbolic path, which means it will pass through once and then head back into interstellar space, never to return.

When you can see it

  • The comet passed closest to the Sun on 29–30 October 2025 and to Earth on 19 December 2025 at about 170 million miles, so the prime geometry window is already under way.
  • NASA notes that 3I/ATLAS should be observable with small telescopes in the pre‑dawn sky until around spring 2026, gradually fading as it recedes.

How to observe it

  • You will need at least a small amateur telescope; it is far too faint to see with the naked eye, expected to be around magnitude 12 or dimmer.
  • The best chances are before sunrise, using up‑to‑date star charts or an astronomy app that includes 3I/ATLAS’s path (often listed as C/2025 N1 (ATLAS)).

Where it is in the sky

  • After solar conjunction, it reappeared in the morning sky from late November/early December 2025 and moves through constellations such as Virgo and Leo while fading.
  • Its exact position on a given night changes, so checking a current ephemeris or a planetarium program for your location and date is essential to point your telescope accurately.

Quick forum-style scoop

  • Latest news pieces describe December 2025–early 2026 as the main “public buzz” window, with many amateur astronomers planning observations and sharing images online.
  • Space agencies (NASA, ESA) are also using major observatories like Hubble, JWST, and Mars‑orbiting spacecraft to study the comet while it crosses the inner solar system, adding to the hype you’re seeing in forums and trending discussions.
