Water is present in virtually every comet seen in the solar system, so much so that the chemical and physical reactions of water are used to measure, catalog, and track these celestial objects and how they react to the heat of the sun. Finding it on 3I/ATLAS means being able to study its characteristics using the same scale used for regular comets, and this information could in future be useful data for studying the processes of comets that originate in other star systems as well.
