Morphology

major + planet

The meaning 'any of the principal planets...' is directly and compositionally derived from 'major' (important/principal) + 'planet' (celestial body). This is a straightforward adjective + noun construction common across languages, so a B1 learner who knows both words would readily infer the MWE's meaning.

Etymology

Major planet may come from the simple image of a major 'bigger' planet that stands out in the Sun's family from small rocks and dwarf planets. That's why it means the main planets that orbit the Sun today.
