Kepler-37b
The artist's concept depicts the new planet dubbed Kepler-37b. The planet is slightly larger than the Moon, measuring about one-third the size of Earth. Kepler-37b orbits its host star every 13 days at less than one-third the distance Mercury is to the Sun. The estimated surface temperature of this smoldering planet, at more than 800 degrees Fahrenheit (700 degrees Kelvin), would melt the zinc in a penny.
Astronomers do not think the tiny planet has an atmosphere or could support life as we know it, but the Moon-size world is almost certainly rocky in composition.Relevante Artikel
