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). 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.
In many cases it is not possible to have an exact value, and an estimated range is instead provided. The coldest and oldest planet directly imaged is Epsilon Indi Ab, which has six times Jupiter's mass, an effective temperature of 275 K, and an age of about 3.5 Ga. This list includes the four members of the multi-planet system that orbit HR 8799.
A planetary phase is a certain portion of a planet's area that reflects sunlight as viewed from a given vantage point, as well as the period of time during which it occurs. The phase is determined by the phase angle , which is the angle between the planet, the Sun and the Earth.
The Znamya project (Russian: Знамя, meaning "Banner", Russian: ⓘ) was a series of orbital space mirror experiments in the 1990s that intended to beam solar power to Earth by reflecting sunlight. The project was the brain child of Vladimir Syromyatnikov, who served as the project's lead engineer. [1]

This template is used to create the ==See also== section at the bottom of each minor planet list page. It also adds a " back to top " link to make the table of contents navigation bar more accessible.
These particles scatter the light, reflecting some of it to the ground. Hence, the sky can remain illuminated even after the sun has set. Images showing a planetary terminator can be used to map topography: the position of the tip of a mountain behind the terminator line is measured when the Sun still or already illuminates it while the base of ...
Earthlight is the diffuse reflection of sunlight reflected from Earth's surface and clouds. Earthshine (an example of planetshine ), also known as the Moon's ashen glow , is the dim illumination of the otherwise unilluminated portion of the Moon by this indirect sunlight.
