Target details ......................... HAT-P-8b
is an extrasolar planet located approximately 720 light years away
in the constellation of Pegasus, orbiting the 10th magnitude star
GSC 02757-01152. This planet was discovered by transit on December
5, 2008. Despite the designation as HAT-P-8b, it is the 11th planet
discovered by the HATNet Project. The mass of the planet is 50% more
than Jupiter while the radius is also 50% more than Jupiter. The
mass of this planet is exact since the inclination of the orbit is
known, typical for transiting planets. This is a so-called “hot
Jupiter” because this Jupiter-like gas giant planet orbits in a
really close torch orbit around the star, making this planet
extremely hot (in the order of a thousand kelvins). The distance
from the star is roughly 20 times smaller than that of Earth from
the Sun, which places the planet roughly 8 times closer to its star
than Mercury is from the Sun. The “year” on this planet lasts only 3
days, 1 hour, 49 minutes, and 54 seconds, compared with Earth's 365
days, 6 hours, 9 minutes, and 10 seconds in a sidereal year. |
