Morphology

red + planet

The phrase 'Red Planet' is a direct composition of 'red' (a color) + 'planet' (a celestial body), so a B1 learner who knows both words will infer it refers to a planet that is red (commonly Mars). This color-descriptive nickname is cross-linguistically transparent and follows normal adjective+noun composition, making the meaning immediately derivable from the constituents.

Etymology

Red Planet comes from the way the red dust on the planet makes it look like rusty soil shining in the sky. So, Red Planet is the simple name people use to mean 'Mars'.
