That star, rather unoriginally, is usually known as 'Sol', if a name other than 'the sun' were to be given for it ??? as per the usual, Sol simply means 'sun' in one of the more pretentious local languages.Up until about a million years ago, a planet in this system had been the homeworld of possibly the greatest spacefaring civilisation that this galaxy, and many other galaxies, had ever known.
