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...
一颗近地大小名为Kepler-442b的系外岩质行星,距离地球1206光年,在这个指数下评级为0.836。作为对比,地球的评级为0.829,居然小于这颗系外行星教育在线观看 地球居然不是最适合人类居住的行星?根据2015年国际天文组织设定的一项星球宜居指数,地球居然并不是宇宙迄今为止发现的最适合居住的行星。一颗近地大小名为Kepler-...

For all targets, with the exception of K2-229b and K2-312b, we also find phase curve variations with a confidence level higher than 2σ. Conclusions. Two USP planets, namely Kepler-10b and Kepler-78b, show non-negligible nightside emission. This questions the scenario of magma-ocean worlds...
Two of the newly validated planets, Kepler-438b and Kepler-442b, are less than 1.5 times the diameter of Earth. Kepler-438b, 475 light-years away, is 12 percent bigger than Earth and orbits its star once every 35.2 days. Kepler-442b, 1,100 light-years away, is 33 percent bigger th...

In this paper an empirical formula is presented for an efficient initial estimate for the iterative solution of Kepler's equation. This formula is essentially a polynomial in eccentricity and mean anomaly whose coefficients have been obtained by minimizing the sum of the squared differences of the ...
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 ...
