Kepler 442b has a mass around double that of the Earth and a radius 30% greater than the Earth. The equilibrium temperature, that is the temperature of the planet if there wasn’t an atmosphere, is 233 K (-40°C; -40°F). Kepler 442b orbits 38,000,000 miles (61,200,000 kilo...
We present a theoretical study on the metallicity dependence of the initial$-$to$-$final mass relation and its influence on white dwarf age determinations... AD Romero,F Campos,SO Kepler - OUP 被引量: 3发表: 2015年 Kepler's Critique of Algebra. Focuses on Johannes Kepler's critique of ...
Kepler-442b is a super-Earth, an exoplanet with a larger mass and radius than Earth but a smaller radius than the ice giants Uranus and Neptune. It has a temperature equilibrium of 233 K (40 °C; 40 °F). It has a diameter of 1.34 R☉. Due to its radius, it is most likely a...
