Origin of interstellar planet

Constructed from Latin: inter- + stellar + planet. The latter derives from Middle English planete, from Old English planēta (“planet, chasuble”), from Latin planeta, planetes, from Ancient Greek πλανήτης (planḗtēs) variant of πλάνης (plánēs, “wanderer, planet”), from πλανάω (planáō, “wander about, stray”), of unknown origin. Perhaps from a Proto-Indo-European *pel- (“to wander, roam”), cognate with Latin pālor (“wander about, stray”), Old Norse flana (“to rush about”), Norwegian flanta (“to wander about”). More at flaunt.
