With a geometric albedo of more than 70% and a Bond albedo as high as 90%, it is also one of the brightest objects in the Solar System. The surface has a reddish tint, owning to the interaction of ...A measure of reflectivity is the albedo, which is often used in the sense of backscattered sunlight in a given spectral region, normally the visual (visual geometric albedo), or the total amount of reflected solar radiation in all directions and spectral bands (bolometric Bond albedo). In the case of asteroids, albedos are an important ...The reflectivity of the earth's surface, the albedo, is a significant factor in the global radiation budget. While affecting the net energy balance of the atmosphere, reflected solar radiation also increases the sky's irradiance due to multiple scattering of air molecules, aerosols and clouds (Iqbal 1983).The amount of reflected solar radiation from the ground depends on surface ...

The Bond albedo, named after the American astronomer George Phillips Bond (1825-1865), who originally proposed it, is the fraction of power in the total electromagnetic radiation incident on an astronomical body that is scattered back out into space.

The bond albedo of an object is simply the average amount of total light that is scattered in any direction by the object. Or essentially its measured diffuse reflectivity.

Cowan (Northwestern University), Eric Agol (University of Washington) [Abridged] If both the day-side and night-side effective temperatures of a planet can be measured, it is possible to estimate its Bond albedo, 0<A_B<1, as well as its day-night heat redistribution ...Earth's planetary Bond albedo decreases from an average of about 0.30 in the "cool" state to an average of about 0.10 in the "warm" state. The dependance of local Bond albedo on local atmospheric temperature is readily apparent on photos of Earth taken from deep space that show varying levels of reflected solar illumination.Since the mean geometric albedo value of the Gallia family is lower than that of the other two families, and since this could imply a lower value of the Bond albedo, we also performed two additional sets of simulations for this family with a value of Bond albedo A Bond = 0.07.

Semoga membantu!While Albedo's former master is the closest thing he has to a parent, Klee and Albedo have developed a bond similar to that of siblings. Klee and Albedo share a special bond, evident in many of ...The albedo is relatively low across the far-UV, with a maximum value of 2.0%. The results show an apparent increase in albedo with decrease in wavelength, implying a "bluing" of the spectrum on all hemispheres. The trailing hemisphere at Lyman-α appears to continue the "bluing" pattern, within the errors; however, the leading ...The planetary albedo or bond albedo A is the fraction of incident radiation, over all wavelengths, which is scattered by the combined effect of the surface and atmosphere of the planet.

En la siguiente tabla se resume los albedos planetarios según de Pater y Lissauer:

Kepler-10b is tidally locked to its parent star and has extreme variations in temperature between day and night sides. It also reflects about half of the starlight it receives. One possible explanation for the high Bond albedo could be that Kepler-10b is a coreless rocky planet with surface magma oceans rich in iron oxides. See also. Kepler-10cAs previously described, Hapke describes this as bihemispherical reflectance, but also indicates this is equivalent to Bond albedo or spherical albedo of a planet. The range of terminology available to describe geometry of reflectance is therefore varied, but on the whole useful for equating reflectance measured to some overall expression of ...The albedo is used to compute 133P's temperature distribution, which shows significant seasonal variation, especially polar regions, ranging from ∼40 to ∼200 K.
