What should be the type of reflection and nature of reflecting surface of artificial moon for better illumination ?
Answers
Answer:
Planetshine is the dim illumination, by sunlight reflected from a planet, of all or part of the otherwise dark side of any moon orbiting the body. Planetlight is the diffuse reflection of sunlight from a planet, whose albedo can be measured.
Saturn's moon Iapetus lit by Saturnshine. This is an enhanced picture; the planetshine is too dim by contrast to be visible to the unaided eye.
The Moon lit by earthshine, captured by the lunar-prospecting Clementine spacecraft in 1994. Clementine's camera reveals (from right to left) the Moon lit by earthshine, the Sun's glare rising over the Moon's dark limb, and the planets Saturn, Mars, and Mercury (the three dots at lower left).
The most observed and familiar example of planetshine is earthshine on the Moon, which is most visible from the night side of Earth when the lunar phase is crescent or nearly new,[1] without the atmospheric brightness of the daytime sky. Typically, this results in the dark side of the Moon being bathed in a faint light.
Planetshine has also been observed elsewhere in the Solar System. In particular, the Cassini space probe used Saturn's shine to image portions of the planet's moons, even when they do not reflect direct sunlight
Answer:
The moon shines because its surface reflects light from the sun. ... This is when the moon is between the sun and the Earth, so that the side of the moon reflecting sunlight is facing away from Earth. In the days before and after a new moon, we'll see a sliver of the moon reflecting sunlight.May 30, 2014
