A new comet, C/2025 V1 Borisov, has been discovered between interstellar object 3I/ATLAS and Earth by astronomer Gennadiy Borisov. Unlike typical comets, it shows no visible tail and moves unusually. Scientists believe it likely formed within our solar system. Detected on November 2, it'll make its closest approach to Earth on November 11, coming within 103 million kilometres.
