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 directly measure their sizes with existing instruments.
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 ... The name was first proposed by Camille Flammarion in his 1880 book ... Triton has an unusually high albedo, ...
In planetary geology, an albedo feature is a large area on the surface of a planet (or other Solar System body) which shows a contrast in brightness or darkness with adjacent areas. Historically, albedo features were the first (and usually only) features to be seen and named on Mars and Mercury .

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 volcano's location corresponds to the classical albedo feature Ascraeus Lacus.. Ascraeus Mons was discovered by the Mariner 9 spacecraft in 1971. The volcano was originally called North Spot [2] because it was the northernmost of only four spots visible on the surface due to a global dust storm that was then enshrouding the planet.
