I entered a system last night and was told by EDDI that I was the first to visit it. After scanning the system I opened my DSS and scanned all 20+ bodies and finding two terraformable planets and one earthlike planet. I then mapped the two terraformables and headed off to map the earthlike world. Funny thing though was the earthlike planet had already been discovered by a Cmdr Quasarsudo. Can anyone explain why this earthlike was already discovered while the rest of the whole system was undiscovered?.
