HAT-P-7b

What is HAT-P-7b?

HAT-P-7b (or Kepler-2b) is an exotic exoplanet orbiting the star HAT-P-7, located in the zodiac constellation Cygnus. HATP-7b, discovered in 2008 by the HATNet Project telescope HAT-7, has a radius larger than Jupiter's and an orbital plane that's tilted so much relative to its star (108°) that the planet is nearly in a polar orbit.

What is special about this exoplanet?

As a result of its relatively close orbit, the planet is unique because of its extreme heat (2730 K | 2456,85°C | 4454,33F). It is also unique since of its cloud composition (made of corundum, mineral that forms rubies and sapphires).

Geomorphology

The radius of HAT-P-7b is 100,042.641 km (62,163.60 miles) and the area of its surface is 125,770,897,514.3298 km² (48,560,395,072.08 miles²).

Anatomy

Strong winds are moving across HAT-P-7b, which causes catastrophic storms. On the cold night side of the planet, clouds form, but on the hot day side, they evaporate quickly. As a result of strong winds circling the planet, clouds are carried from the nightside to the dayside. Large cloud formations build up and then dissipate as the winds change their speed.

HAT-P-7b has a mass of 1.84 Jupiters (3,492,320,000,000,000,300,000,000,000 tons) and has a density of 0.54 g/cm³.

Tectonic plates

Studies of the tectonic plates of HAT-P-7b has yet to be made.

Location

HAT-P-7b is 1112.2 light-years away from Earth. Its orbital distance is 0.03676 AU.

Physico-chemical properties

It is thought that HAT-P-7b's clouds are composed of vaporized corundum, which is a mineral that forms rubies and sapphires.

Temperature

The planet is predicted to have a dayside temperature of 2,630-2,880 K (4,270-4,720°F | 2,360-2,610°C), while nightside temperatures are 2,211-2,238 K (3,520-3,569°F | 1,938-1,965°C).

Age

We do not know its age.

Gravitational force

This extra solar planet has a surface gravity of 17.36 m/s² (56.955381 ft/s²).

Magnetic field

Simulation of magnetic field lines in the atmosphere of HD209458 b with a similar temperature structure to HAT-P-7 b. Azimuthal (toroidal) magnetic field lines are colour-coded, with blue representing a negatively-directed field (with saturation at -50 G) and magenta representing a positively-directed field (with saturation at 50 G), then green and yellow corresponding to -5 and 5 G, respectively. From this vantage point, you can see the east-side terminator.

Orbit

It takes 2.2 days for HAT-P-7b to complete one orbit around its star.

Rotation

HAT-P-7b is a tidally locked exoplanet.

Moon system

HAT-P-7b does not have any moons.

Ring system

HAT-P-7b does not possess any rings.
