Reflectivity - The ability of a surface to reflect electromagnetic waves. The reflectivity of a surface ranges from 0% for a surface that reflects no light to 100% for a surface that reflects all the light falling on it ...

Based on (reflectivity), and color or spectra. Most common are C, S, and M.
(lb´d), reflectivity of the surface of a planet, moon, asteroid, or other celestial body that does not shine by its own light. Albedo is measured as the fraction of incident light that the surface reflects back in all directions.
radar reflectivity In general, the measure of the efficiency of a radar target in intercepting and returning a radar signal. It depends upon the size, shape, aspect, and the dielectric properties at the surface of the target.
The albedo, or reflectivity, of the surfaces of both satellites is very low, similar to that of the most primitive types of meteorites. One theory of the origin of the satellites is that they are asteroids that were captured when Mars was forming.
(4k jpg) albedo the ratio of the amount of light reflected by an object and the amount of incident light; a measure of the reflectivity or intrinsic brightness of an object (a white, perfectly reflecting surface would have an albedo of 1.
sense-reversing reflectivity (NASA SP-7, 1965) The characteristic of a reflector that reverses the sense of a circularly polarized incident ray. See polarization.
albedo surface reflectivity altitude the angular distance of an object above or below the horizon angstrom (Å) commonly used to measure the wavelength of light; ...
albedo Reflectivity of an object; ratio of reflected light to incident light. albedo feature A dark or light marking on the surface of an object that might not be a geological or topographical feature.
The same clouds whose reflectivity makes Venus so easy to see in the night sky also make it impossible for us to discern any surface features on the planet, at least in visible light.
If you consider a planet with the same reflectivity (clouds and surface material) as the Earth, reradiates the solar energy it absorbed as efficiently as the Earth does, and rotates as quickly as the Earth does, ...
Film reflectivity was measured over time by a photovoltaic sensor. Changes in reflectivity indicate the amount of abrasion on the different films due to rolling wear.
But a strange phenomena had been noted based on changes in the ices' reflectivity and temperature: carbon dioxide ice that had disappeared in the early northern hemisphere spring, suddenly reappeared.
The objects present wide range of spectra, differing in reflectivity in visible red and near infrared. Neutral objects present a flat spectrum, reflecting as much red and infrared as visible spectrum.
Asteroids are classified according to their chemical composition, based on observed spectra and albedo (reflectivity). More than 75% are C-type asteroids which are dark and reddish with an albedo less than 0.10.
Visual albedo is defined by the "reflectivity of the surface of a planet, moon, asteroid, or other celestial body that does not shine by its own light.
It is therefore a more specific form of the term reflectivity....

Its albedo, or reflectivity, is high (84 percent of the light falling on it is reflected), but it is so far away from the earth its stellar magnitude (a scale used to describe the brightness of an astronomical object; ...
The initial reflectivity of silver (89 to 93%) is slightly higher than that of aluminum throughout most of the visible spectrum, but this advantage is short-lived because silver quickly tarnishes, ...
Measure of the reflectivity of the object. It is defined as the fraction of the received light that is reflected into space.
Phaethon's attributes (orbit, size, reflectivity, and association with an annual meteor shower) can be argued as being cometary, except that Phaethon has never been caught exhibiting a coma, gas jets, or dust trail.
The (reflectivity), , and radius of an asteroid may be determined by measuring the infrared and visible fluxes at .
The blue icy plains show different levels of reflectivity, or albedo, because of differences in the size of the grains of the ice.
The image covers an area about 780 miles across. The resolution is about one to two miles per picture element.
Albedo is the measure of the reflectivity of a planet, measured on a scale from zero to one. An albedo of zero describes a planet that absorbs all the light it receives. A planet with an albedo of one reflects all the light that shines on it.
Cassini was used to obtain images of the asteroid at a distance of 1.6 million km. These were used to determine its size, reflectivity, composition and rotation period. The results indicate that Masursky is between 15 and 20 km across.

A regio is an area which is disctinctive from surrounding regions due to a difference in reflectivity or color.

of solar radiation reflected from an object to the total amount it receives. An object with a high albedo is shinier than an object with a low albedo. A white, completely reflecting object has an albedo of 1.0; a black object with no reflectivity has ...

to the reflecting surface (angle of incidence) is equal to the angle between the direction of motion of the reflected wave and a perpendicular (angle of reflection). Reflection at rough, or irregular, boundaries is diffuse. The reflectivity of a ...
Earlier estimates placed the number of such large NEAs at about 2,000, but closer examination of NEAs showed that their reflectivity had been underestimated slightly, making them seem bigger than they really were.
of revolution, accounting for the fact that virtually the same portion of the moon is always turned toward the earth. Although the moon appears bright to the eye, it reflects into space only 7 percent of the light that falls on it. The reflectivity, ...
