Kepler-7 is a star located in the constellation Lyra in the field of view of the Kepler Mission, a NASA operation in search of Earth-like planets. It is home to the fourth of the first five planets that Kepler discovered; this planet, a Jupiter-size gas giant named Kepler-7b, is as light as styrofoam. [6]
Kepler-7 b is a gas giant exoplanet that orbits a G-type star. Its mass is 0.441 Jupiters, it takes 4.9 days to complete one orbit of its star, and is 0.06067 AU from its star. Its discovery was announced in 2009.
Kepler-7b is a hot Jupiter, a Jupiter-like exoplanet orbiting close to its star. Its equilibrium temperature, due to its proximity to its star, is hot and is measured at nearly 1540 K. However, of the first five planets discovered by Kepler, it is the second coolest, being surpassed only by Kepler-6b. [4] .
18 Μαΐ 2016 · Kepler-7b, a sizzling, Jupiter-like world was the first planet to have its clouds mapped. Tidally locked, with one side in constant scorching daylight and the other in endless freezing night, the map allowed scientists to learn that planetary weather could conduct superheated air from one side of the planet to the other.
30 Σεπ 2013 · Astronomers using data from NASA’s Kepler and Spitzer space telescopes have created the first cloud map of a planet beyond our solar system, a sizzling, Jupiter-like world known as Kepler-7b. The planet is marked by high clouds in the west and clear skies in the east.
30 Μαρ 2010 · We report on the discovery and confirmation of Kepler-7b, a transiting planet with unusually low density. The mass is less than half that of Jupiter, MP = 0.43 MJ, but the radius is 50% larger, RP = 1.48 RJ. The resulting density, ρ P = 0.17 g cm −3, is the second lowest reported so far for an extrasolar planet.
3 Οκτ 2013 · Scientists use data from NASA's Kepler and Spitzer space telescopes to generate the first map of clouds on an exoplanet. They find that Kepler 7b, a hot Jupiter, has a lopsided cloud distribution that reflects a lot of its star's light.
