A reflective lava world is challenging scientists to understand
A reflective lava world is challenging scientists to understand.
It is an exoplanet, a planet beyond our solar system.
Kepler and TESS have found many ultra-short-period planets, which complete an orbit in less than 24 hours.
These planets move much faster in their orbits than Mercury does around the Sun.
Mercury takes 88 days to complete one orbit, a pace once considered fast by ancient astronomers.
The unusual world highlights how much there is to understand about the planets discovered by these missions.
