Etymology edit

PIE word
*sóh₂wl̥

Borrowed from Late Latin perihelium, from Ancient Greek περί- (perí-) (a variant of περι- (peri-, prefix meaning ‘around; surrounding’), ultimately from Proto-Indo-European *per- (before, in front; first)) + ἥλιος (hḗlios, sun) (ultimately from Proto-Indo-European *sóh₂wl̥ (sun) or a pre-Hellenic language), which was modelled after perigeum (point in an orbit about the Earth that is closest to the Earth, perigee).[1]
