Comet C/2025 A6 (Lemmon) is just weeks away from a close approach to Earth that could make it visible to the naked eye in the October night sky. Read on for spectacular views of this wandering comet and its magnificent tail as captured by astrophotographers around the world.

Astronomers discovered Comet C/2025 A6 (Lemmon) on Jan. 3 using a 60-inch telescope located at the Mt.Lemmon Observatory in Arizona. The comet is currently heading farther into the solar system and will make its closest approach to Earth on Oct. 21, passing a little over 55 million miles (89 million kilometers) from our planet, before heading on to perihelion — its closest point to the sun — on Nov. 8.
