HD 209458 b
HD 209458 b, which is also nicknamed Osiris after the Egyptian god, is an exoplanet that orbits the solar analog HD 209458 in the constellation Pegasus, some from the Solar System. The radius of the planet's orbit is , or one-eighth the radius ...
. The most massive transiting exoplanet is
KELT-1b
KELT-1 is a F-type main-sequence star. Its surface temperature is 6518 K. It is similar to the Sun in its concentration of heavy elements, with a metallicity Fe/H index of 0.008, but is much younger at an age of 1.75 billion years. The ...
