  2. Moonrise and moonset - Wikipedia

    en.wikipedia.org/wiki/Moonrise_and_moonset

    A waxing gibbous Moon, rising over mountains with coniferous trees. The Moon's position relative to Earth and the Sun determines the moonrise and moonset time. For example, a last quarter rises at midnight and sets at noon. [5] A waning gibbous is best seen from late night to early morning. [6]

    en.wikipedia.org/wiki/Lunar_theory

    The most significant improvement of position observations of the Moon have been the Lunar Laser Ranging measurements, obtained using Earth-bound lasers and special retroreflectors placed on the surface of the Moon. The time-of-flight of a pulse of laser light to one of the retroreflectors and back gives a measure of the Moon's distance at that ...

  4. Lunar precession - Wikipedia

    en.wikipedia.org/wiki/Lunar_precession

    Since the Moon's axial tilt is only 1.5° with respect to the ecliptic (the plane of Earth's orbit around the Sun), this effect is small. Once every 18.6 years, [ 1 ] the lunar north pole describes a small circle around a point in the constellation Draco , while correspondingly, the lunar south pole describes a small circle around a point in ...

  5. Libration - Wikipedia

    en.wikipedia.org/wiki/Libration

    The two angles are created by the different position of the observer with respect to the Moon due to the rotation of Earth over a few hours. In lunar astronomy, libration is the cyclic variation in the apparent position of the Moon perceived by Earth-bound observers and caused by changes between the orbital and rotational planes of the moon. It ...

  6. Moon - Wikipedia

    en.wikipedia.org/wiki/Moon

    The Moon's highest altitude at culmination varies by its lunar phase, or more correctly its orbital position, and time of the year, or more correctly the position of the Earth's axis. The full moon is highest in the sky during winter and lowest during summer (for each hemisphere respectively), with its altitude changing towards dark moon to the ...

  7. Lunar phase - Wikipedia

    en.wikipedia.org/wiki/Lunar_phase

    The Earth subtends an angle of about two degrees when seen from the Moon. This means that an observer on Earth who sees the Moon when it is close to the eastern horizon sees it from an angle that is about 2 degrees different from the line of sight of an observer who sees the Moon on the western horizon. The Moon moves about 12 degrees around ...

  8. Dust from the moon could help slow climate change, study finds

    A new study published on Wednesday suggested that a deep-space umbrella of lunar dust could help slow the effects of climate change. The study, published in the PLoS science journal, explains how ...

  9. Full moon - Wikipedia

    en.wikipedia.org/wiki/Full_moon

    For example, the crescent moon is 'banana' shaped, and the half-moon is D-shaped. When the moon is nearly full, it is called a gibbous moon. The crescent and gibbous moons each last approximately a week. [5] Each phase is also described in accordance to its position on the full 29.5-day cycle. The eight phases of the moon in order: [5] new moon
