jan 1, 2241 - From Sonra to "Argon"
Description:
71 NTSonra is renamed R Gunne in honor of the late Nathan Gunne, which quickly becomes the more onomatopoeic "Argun". "Prime" is later added to infer that this planet was the first of many colonies, and over the years language drift would change "Argun" to "Argon".
