lava planet

Globe of magma

A lava planet is a type of exoplanet with a surface dominated by molten rock—oceans of magma rather than water.

These worlds orbit extremely close to their stars, with surface temperatures hot enough to melt stone.

The term appears in astronomy and science fiction: The probe detected a lava planet orbiting just four million miles from its star.
