3I/ATLAS's strange behavior intensifies as it approaches Earth.

The interstellar object 3I/ATLAS has approached Earth to a distance of approximately 270 million kilometers and continues to exhibit unusual behavior. It is becoming brighter and taking on a greenish tint, which is due to active evaporation and changes in the composition of its coma under the influence of solar radiation. Astronomers are recording increased activity, including variations in the brightness and structure of the gas and dust cloud around the nucleus, which distinguishes it from typical comets in the Solar System.
