albedo, fraction of light that is reflected by a body or surface. It is commonly used in astronomy to describe the reflective properties of planets, satellites, and asteroids. It is an important consideration in climatology since recent albedo decreases in the Arctic have increased heat absorption at the surface.
- E = total energy intercepted (technically, energy flux = energy per unit time, in watts)
- KS = solar insolation (“solar constant”) = 1,361 watts per square meter.
- RE = radius of Earth = 6,371 km = 6,371,000 meters.
Since planets and moons do not emit light, the only reason we can see them is because they reflect light from some other source. … The amount of sunlight incident on a moon or planet that gets reflected depends on the materials in its surface and atmosphere as well as its surface roughness.
The lunar albedo (fractional reflectivity) is only about 0.12 – in other words, over the visible spectrum, it reflects a mere 12% of the light hitting it, absorbing the rest.
Albedo in Solar panels usually convert 16.67% of the incident radiation to direct current. The rest is dissipated as heat. Albedo measures the diffused and reflected solar radiation incident from any astronomical body. The range of the albedo is the zero to one.
From Dust to Chalk Albedo has heavily hinted that he was created rather than born. Aside from Homuncular Nature being one of the names of his talents, Albedo remarks that he has no memory of relatives and his earliest memories are of him traveling with his teacher, Rhinedottir.
Albedo is an expression of the ability of surfaces to reflect sunlight (heat from the sun). … Light-coloured surfaces return a large part of the sunrays back to the atmosphere (high albedo). Dark surfaces absorb the rays from the sun (low albedo).
Planet Earth has been called the “Blue Planet” due to the abundant water on its surface. Here on Earth, we take liquid water for granted; after all, our bodies are mostly made of water. However, liquid water is a rare commodity in our solar system.
During a total lunar eclipse, Earth lines up between the Moon and the Sun. This hides the Moon from the sunlight. … The air molecules from Earth’s atmosphere scatter out most of the blue light. The remaining light reflects onto the Moon’s surface with a red glow, making the Moon appear red in the night sky.
Mars. … Because the atmosphere of Mars is very thin, its albedo, at 29 percent, is dominated by the relatively dark surface.
As you might have guessed, Venus has the highest albedo of any major planet in our solar system.
| Jupiter | Ratio (Jupiter/Earth) | |
|---|---|---|
| Bond albedo | 0.343 | 1.12 |
| Geometric albedo | 0.538 | 1.24 |
| V-band magnitude V(1,0) | -9.40 | – |
| Solar irradiance (W/m2) | 50.26 | 0.037 |
Key Takeaways: Modern PV panels reflect as little as two percent of incoming sunlight, about the same as water and less than soil or even wood shingles.
The higher the albedo, the more the surface reflects light. Snow and ice have high albedos; a dark rock would have a lower albedo. … More, the more the surface reflects light. Snow and ice have high albedos; a dark rock would have a lower albedo. The higher the albedo, the more the surface reflects light.
Bifacial modules produce solar power from both sides of the panel. Whereas traditional opaque-backsheeted panels are monofacial, bifacial modules expose both the front and backside of the solar cells.
Albedo and Klee aren’t blood-related, but Alice helped to take care of Albedo and asked that he think of Klee as his sister. The two have taken on a sibling-like relationship, and Albedo is close to Klee.
Albedo was a short and slender young man with pale skin and a golden diamond-shaped mark at the center of his neck.
Equipment. Albedo originally had an Omnitrix he had built himself, giving him access to all of Ben’s unlocked alien forms. However, his Omnitrix was only working by syncing data from Ben’s Omnitrix, inadvertently causing him to assume Ben’s form as it was the default.
More sunlight is absorbed in the area and the temperatures increase. … Trees are dark and have a low albedo, so removing trees might actually increase the albedo of an area; especially regions typically covered in snow during the winter. Clouds can reflect sunlight, but they can also trap heat warming up the planet.
« Back to Glossary Index. The amount of light that is reflected off of an object like the Earth.
If Earth’s climate is colder and there is more snow and ice on the planet, albedo increases, more sunlight is reflected out to space, and the climate gets even cooler.
Since the Earth is flattened at the poles and bulges at the Equator, geodesy represents the figure of the Earth as an oblate spheroid. The oblate spheroid, or oblate ellipsoid, is an ellipsoid of revolution obtained by rotating an ellipse about its shorter axis.
Earth is rightfully called a water-world: far more than half of our planet is covered in water. … That’s because the ocean covers 71 percent of Earth’s surface. The ocean is accordingly a major component of the hydrosphere, and it plays an important role in Earth’s water cycle.
Earth is the only known planet of the solar system which supports life. Earth has oxygen, water and temperature. … All these conditions which are supporting life, like presence of water and air in a good proportion, presence of life supporting gas and balanced temperature make earth a unique planet.
North America is about to be treated to three significant solar eclipses. On June 10, 2021, anyone under clear skies within a path that sweeps across the remote arctic will see an annular (“ring”) eclipse.
The moon shines because its surface reflects light from the sun. And despite the fact that it sometimes seems to shine very brightly, the moon reflects only between 3 and 12 percent of the sunlight that hits it. The perceived brightness of the moon from Earth depends on where the moon is in its orbit around the planet.
An eclipse of the Sun happens when the New Moon moves between the Sun and Earth, blocking out the Sun’s rays and casting a shadow on parts of Earth. The Moon’s shadow is not big enough to engulf the entire planet, so the shadow is always limited to a certain area (see map illustrations below).
Saturn. Saturn has 53 moons that have been named. Saturn also has 29 moons awaiting confirmation.
Uranus is the seventh planet from the Sun, and has the third-largest diameter in our solar system. It was the first planet found with the aid of a telescope, Uranus was discovered in 1781 by astronomer William Herschel, although he originally thought it was either a comet or a star.
Pluto is now classified as a dwarf planet because, while it is large enough to have become spherical, it is not big enough to exert its orbital dominance and clear the neighborhood surrounding its orbit.
Mercury is the smallest planet in our solar system. … Along with Venus, Earth, and Mars, Mercury is one of the rocky planets. It has a solid surface that is covered with craters. It has no atmosphere, and it doesn’t have any moons.
Venus also shows evidence of tectonic activity, where the surface has been, in some locations, stretched and broken, and in other regions, crumpled.
Jupiter is primarily composed of hydrogen, but helium constitutes one quarter of its mass and one tenth of its volume. It likely has a rocky core of heavier elements, but like the other giant planets, Jupiter lacks a well-defined solid surface.
Venus can often be seen within a few hours after sunset or before sunrise as the brightest object in the sky (other than the moon). It looks like a very bright star. Venus is the brightest planet in the Solar System.
Venus presents a thin crescent in telescopic views as it comes around to the near side between the Earth and the Sun and presents its new phase when it is between the Earth and the Sun. Since the planet has an atmosphere it can be seen at new in a telescope by the halo of light refracted around the planet.
Well, a lot of rocks on Mars are full of iron, and when they’re exposed to the great outdoors, they ‘oxidize’ and turn reddish – the same way an old bike left out in the yard gets all rusty. When rusty dust from those rocks gets kicked up in the atmosphere, it makes the martian sky look pink.
Fifth in line from the Sun, Jupiter is, by far, the largest planet in the solar system – more than twice as massive as all the other planets combined.
The bright regions (albedo > 0.4) are mainly localised over the Tharsis plateau, Arbia Terra and Elysium Planitia regions of Mars. … In general low albedo values are associated with darker surface on Mars having volcanic rock basalt on surface. Higher albedo values represents surface covered by Dust.
Pluto, once considered the ninth and most distant planet from the sun, is now the largest known dwarf planet in the solar system. … Pluto was finally discovered in 1930 by Clyde Tombaugh at the Lowell Observatory, based on predictions by Lowell and other astronomers.
