  2. Lunar phase - Wikipedia

    en.wikipedia.org/wiki/Lunar_phase

    The term waxing is used for an intermediate phase when the Moon's apparent shape is thickening, from new to a full moon; and waning when the shape is thinning. The duration from full moon to new moon (or new moon to full moon) varies from approximately 13 days 22 + 1 ⁄ 2 hours to about 15 days 14 + 1 ⁄ 2 hours.

  3. Full moon - Wikipedia

    en.wikipedia.org/wiki/Full_moon

    The supermoon of 14 November 2016 was 356,511 km (221,526 mi) away [1] from the center of Earth. Supermoons occur 3–4 times per year. [2] As the Earth revolves around the Sun, approximate axial parallelism of the Moon's orbital plane (tilted five degrees to the Earth's orbital plane) results in the revolution of the lunar nodes relative to the Earth.

  4. Lunar calendar - Wikipedia

    en.wikipedia.org/wiki/Lunar_calendar

    A lunisolar calendar was found at Warren Field in Scotland and has been dated to c. 8000 BC, during the Mesolithic period. [2] [3] Some scholars argue for lunar calendars still earlier—Rappenglück in the marks on a c. 17,000 year-old cave painting at Lascaux and Marshack in the marks on a c. 27,000 year-old bone baton—but their findings remain controversial.

  5. Lunar month - Wikipedia

    en.wikipedia.org/wiki/Lunar_month

    The apparent diameter of the Moon varies with this period, so this type has some relevance for the prediction of eclipses (see Saros), whose extent, duration, and appearance (whether total or annular) depend on the exact apparent diameter of the Moon. The apparent diameter of the full moon varies with the full moon cycle, which is the beat ...

  6. Lunar observation - Wikipedia

    en.wikipedia.org/wiki/Lunar_observation

    Contrary to popular belief, the Moon should ideally not be viewed at its full phase. During a full moon, rays of sunlight are hitting the visible portion of the Moon perpendicular to the surface. As a result, there is less surface detail visible during a full moon than during other phases (such as the quarter and crescent phases) when sunlight ...

  8. Moon - Wikipedia

    en.wikipedia.org/wiki/Moon

    The Moon is Earth's only natural satellite. It orbits at an average distance of 384,400 km (238,900 mi), about 30 times the diameter of Earth. Tidal forces between Earth and the Moon have synchronized the Moon's orbital period (lunar month) with its rotation period at 29.5 Earth days, causing the same side of the Moon to always face Earth.

  9. Metonic cycle - Wikipedia

    en.wikipedia.org/wiki/Metonic_cycle

    The traditional lunar year of 12 synodic months is about 354 days, approximately eleven days short of the solar year. Thus, every 2 to 3 years there is a discrepancy of 22 to 33 days, or a full synodic month. For example, if the winter solstice and the new moon coincide, it takes 19 tropical years for the coincidence to recur.
