Ophion is a star cluster in the constellation Ophiuchus.[1] The cluster consists of over 1,000stars at around 20million years of age.[2] Ophion is located around 650lightyears from Earth.[3] The cluster is separating quickly for a star cluster, in a process known as velocity dispersion.[1] As measured by Gaia, the velocity dispersion is 72,000 kilometres per hour (45,000mph).[1] The pace of diversion was likely aided by a supernova along with galactic tides, the most common source of dispersion in star clusters.[1]
