The largest of these may have a hydrostatic-equilibrium shape, but most are irregular. Most of the trans-Neptunian objects (TNOs) listed with a radius smaller than 200 km have "assumed sizes based on a generic albedo of 0.09" since they are too far away to
When seen from a distance, the ocean surface has a low albedo, as do most forests, whereas desert areas have some of the highest albedos among landforms. Most land areas are in an albedo range of 0.1 to 0.4. [14] The average albedo of Earth is about 0.3. [15] This is far higher than for the ocean primarily because of the contribution of clouds.
Triton is the largest natural satellite of the planet Neptune. It is the only moon of Neptune massive enough to be rounded under its own gravity and hosts a thin, hazy atmosphere. Triton orbits Neptune in a retrograde orbit—revolving in the opposite direction to the parent planet's rotation—the only large moon in the Solar System to do so.
Largest ratio of rotation rate to breakup velocity Kappa Andromedae b: Kappa Andromedae ~ 0.5 [39] Hottest (irradiated hot Jupiter) KELT-9b: KELT-9: 4050 ± 180 K [1] (3777 °C) The unconfirmed planets Kepler-70b and Kepler-70c may be hotter, both at >6800 K (assuming an albedo of 0.1 for both).

For the maximum estimated diameter (137 km), the minimum albedo of the nucleus would be 3.3% ± 0.9%. [9] C/2014 UN 271 's low albedo is characteristic of small comet nuclei from both short- and long-period populations, suggesting a lack of correlation between albedo, nucleus size, and orbit type in Solar System comets.

The first albedo feature ever seen on another planet was Syrtis Major Planum on Mars in the 17th century. [ 3 ] [ 4 ] Today, thanks to space probes, very high-resolution images of surface features on Mars and Mercury are available, and the classical nomenclature based on albedo features has fallen somewhat into disuse, although it is still used ...
Kepler-7 is the largest host star of the first five planets detected by ... It was found that Kepler-7b has a relatively high geometric albedo of 0.3. [16] References
