COROT-7bとは 意味・読み方・使い方

COROT-7b (previously named COROT-Exo-7b) is a reported exoplanet orbiting around the star COROT-7, in constellation Monoceros, at 489 light years from Earth. It was first detected photometrically by the French-led COROT mission and reported in February 2009. Until the announcement of Kepler-10b in January 2011, it was the smallest exoplanet to have its diameter measured, at 1.58 times that of the Earth (which would give it a volume 3.95 times Earth's), and the first potential extrasolar terrestrial planet to be found. The planet is also notable for its very short orbital period, revolving around its host star in less than one day.
