Morphology

90377 + Sedna

This form combines a numeric catalogue designation with the proper name Sedna; since 'Sedna' denotes the distant planetoid, the overall referent is directly recoverable from the constituents. The number '90377' merely specifies its catalogue entry and does not alter the meaning, so a B1 learner who knows the parts would understand the MWE.

Etymology

90377 Sedna takes its name from Sedna, the sea goddess in Inuit stories. In those tales she lives deep under a cold, distant sea, so astronomers chose her name to give a clear image of a very 'distant' and cold world at the edge of our solar system.
