Morphology

extraterrestrial + object

The meaning is a straightforward composition of 'extraterrestrial' (originating beyond Earth) and 'object' (a thing), so a learner who knows both words can directly infer 'a thing existing outside Earth/its atmosphere.' The adjective+noun pattern is a standard, cross-linguistically common construction, making the phrase immediately comprehensible to B1 learners who know the constituents.

Etymology

Extraterrestrial object comes from two parts: extra meaning 'outside' and terrestrial meaning 'of the Earth'. So, the phrase gives the image of something that is literally 'outside the Earth', which is why we use it for natural things from space like meteorites.
