"[Our philosopher] asserted that he knew the whole secret...[H]e surveyed the two celestial strangers from top to toe, and mantained to their faces that their persons, their worlds, their suns and their stars, were created solely for the use of man. At this assertion our two travelers let themselves fall against each other, seized with a fit of...inextinguishable laughter"

Fiery ‘Lava-World’ Alien Planet Discovered | The Daily Galaxy
Researchers at MIT have discovered an Earth-sized exoplanet named Kepler 78b that whips around its host star in a mere 8.5 hours — one of the shortest orbital periods ever detected. The planet is extremely close to its star — its orbital radius is only about three times the radius of the star — and the scientists have estimated that its surface temperatures may be as high as 3,000 degrees Kelvin, or more than 5,000 degrees Fahrenheit. In such a scorching environment, the top layer of the planet is likely completely melted, creating a massive, roiling ocean of lava.
