What temperature is the dark side of Venus?
About as inhospitable as can be—with temperatures pushing 900 degrees Fahrenheit, sulphuric acid rains, and surface pressures equivalent to the depths of Earth’s oceans—Venus is unique in the solar system for another reason as well.

What planet is habitable?
A 2015 review concluded that the exoplanets Kepler-62f, Kepler-186f and Kepler-442b were likely the best candidates for being potentially habitable. These are at a distance of 1,200, 490 and 1,120 light-years away, respectively.
Is there a planet made of diamonds?
In 2012, scientists announced they had discovered an exoplanet twice the size of Earth believed to be made largely of diamond. Astronomers said the rocky planet, called 55 Cancri e, was likely covered in graphite and diamond, rather than water and granite.
