Interstellar Comet 2I/Borisov
Artist impression of the interstellar comet 2I/Borisov as it travels through our solar system. This mysterious visitor from the depths of space is the first conclusively identified comet from another star. The comet consists of a loose agglomeration of ices and dust particles, and is likely no more than 3,200 feet across, about the length of nine football fields. Gas is ejected out of the comet as it approaches the Sun and is heated up.
