kepler 10c diameter

Ce processus aurait pris des milliards d'années. Néanmoins, de nouvelles données ont permis en juin 2014 de déterminer une masse d'environ 17 masses terrestres et donc une densité de 7 g/cm3, faisant de cette planète un objet d'un nouveau type, une planète composée principalement d'éléments lourds (roches, métaux) tout en ayant une masse bien supérieure à la limite prévue par les modèles de 10-12 masses terrestres à partir de laquelle l'accrétion d'une grande quantité de gaz (hélium, hydrogène) devrait se produire[2]. Kepler-10c was known to have a diameter of about 29,000 km, about 2.3 times as large as Earth. At that time, however, while Kepler-10c's orbital period (45 days) and diameter (2.3 times Earth) were known, its mass hadn't been worked out – and when it was, it turned out to be a surprise.

The planet which is 560 light-years away from Earth is actually too large for a classical planet. Kepler-10c has a diameter of about 18,000 miles, 2.3 times as large as Earth, researchers said. Kepler-10c est une très vieille planète. Elle s'est formée il y a près de 10 milliards d'années à une époque de l'univers où les éléments lourds étaient très rares, alors que la première génération d’étoiles s'éteignait en supernovae, dispersant dans l'espace les nouveaux matériaux fabriqués et annonçant les étoiles de population II. Il n'est pas possible de dire si l'objet en question est une planète tellurique ou gazeuse. ©. Offre de noël : le VPN Surfshark casse les prix avec 83 % de réduction ! The same technique is used to determine a celestial body’s diameter, and found that Kepler-10c measured 29,000 km. Kepler-10c was originally spotted by NASA’s Kepler Space Telescope in May 2011. There is no evidence for this. It must be tidally locked, so must be molten on its dayside, but its surface would be solid on its cold nightside. It has a diameter 1.47 times that of the Earth. However, Kepler can’t tell whether a planet is rocky or gassy.
