  2. Albedo - Wikipedia

    en.wikipedia.org/wiki/Albedo

    A layer of snowfall increases local albedo, reflecting away sunlight, leading to local cooling. In principle, if no outside temperature change affects this area (e.g., a warm air mass ), the raised albedo and lower temperature would maintain the current snow and invite further snowfall, deepening the snow–temperature feedback.

  3. Planetshine - Wikipedia

    en.wikipedia.org/wiki/Planetshine

    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.

  4. Space mirror - Wikipedia

    en.wikipedia.org/wiki/Space_mirror

    Space mirrors are designed either to increase or decrease the amount of energy that reaches a planet from the sun with the goal of changing the impact of UV radiation; or, to reflect light onto or deflect light off of a planet in order to change the sun's lighting conditions.

  5. Navagraha - Wikipedia

    en.wikipedia.org/wiki/Navagraha

    The nine parts of the navagraha are the Sun, Moon, planets Mercury, Venus, Mars, Jupiter, and Saturn, and the two nodes of the Moon. [2] A typical navagraha shrine found inside a Hindu temple. The term planet was applied originally only to the five planets known (i.e., visible to the naked eye) and excluded the Earth.

  6. Terminator (solar) - Wikipedia

    en.wikipedia.org/wiki/Terminator_(solar)

    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 ...

  7. Solar System - Wikipedia

    en.wikipedia.org/wiki/Solar_System

    Thus, the Sun occupies 0.00001% (1 part in 10 7) of the volume of a sphere with a radius the size of Earth's orbit, whereas Earth's volume is roughly 1 millionth (10 −6) that of the Sun. Jupiter, the largest planet, is 5.2 AU from the Sun and has a radius of 71,000 km (0.00047 AU; 44,000 mi), whereas the most distant planet, Neptune, is 30 AU ...

  8. Zodiacal light - Wikipedia

    en.wikipedia.org/wiki/Zodiacal_light

    Zodiacal light is produced by sunlight reflecting off dust particles in the Solar System known as cosmic dust. Consequently, its spectrum is the same as the solar spectrum. The material producing the zodiacal light is located in a lens-shaped volume of space centered on the sun and extending well out beyond the orbit of Earth.

  9. Solar radiation modification - Wikipedia

    en.wikipedia.org/wiki/Solar_radiation_modification

    Solar radiation modification (SRM) (or solar radiation management or sunlight reflection methods [1] or solar geoengineering), is a group of large-scale approaches to limit global warming by increasing the amount of sunlight (solar radiation) that is reflected away from Earth and back to space.
