Filed under pretty pictures, art, extrasolar planets, astronomy and astrophysics spacecraft, Kepler
An artist's concept of the smallest two of five planets suspected to orbit the star Kepler-20, compared to Earth and Venus. These two planets orbit very close to their star so would be much hotter than Earth and Venus. Their diameters are about 87% and 103% that of Earth, give or take 10%.
