How to use in-sentence of “albedo”:
– The Kuiper Belt Electronic newsletter, March 2007 Assuming an albedo similar to that of the primary, the magnitude suggests a diameter of about 220km.
– Unfortunately, other than its orbit, radius of 23km and geometric albedo of 0.08, almost nothing is known about it.
– It takes 15.4 hours to orbit each other, which says that the binary is very close — the separation being of the order of 10–20km, if normal asteroid albedo and density values are assumed.
– Based on its size, Brown lists it as nearly certain to be a dwarf planet, however, its low albedo may imply the opposite: dark, mid-sized bodies such as this, less than about 1000 km in diameter and with albedos less than about 0.2, have likely never collapsed into solid bodies, much less differentiated or relaxed into hydrostatic equilibrium, and thus are unlikely to be dwarf planets.
– Within a century, astronomers discovered distinct albedo features on the planet, including the dark patch and polar ice caps.
– Earth’s albedo is three times as high as that of the Moon, and coupled with the wider area, the “full Earth” glows over 50 times brighter than the “full Moon” does for the observer on Earth.
– Albiorix orbits Saturn at a distance of about 16,000,000 km and its diameter is estimated at 32 kilometers, assuming an albedo of 0.04.
