    Study Notes

    Phases of the Moon

    • The phases of the moon are caused by its spherical shape and orbital motion around Earth.
    • The moon's phases are determined by the relative positions of the Sun, Earth, and Moon.

    Moon's Orbit

    • The moon moves about 13° eastward in the sky each night.
    • The moon's synodic period is the time it takes for the moon to repeat its cycle of phases, which is approximately 29.5 days.
    • The moon's sidereal period is the time it takes for the moon to orbit Earth once with respect to the stars.

    Lunar Eclipse

    • A lunar eclipse occurs when Earth passes between the Sun and the Moon, blocking the Sun's light from reaching the Moon.
    • A total lunar eclipse occurs when the Moon is in Earth's umbra.
    • The Moon appears coppery red during a total lunar eclipse because red light is better able to pass through Earth's atmosphere.

    Solar Eclipse

    • A solar eclipse occurs when the Moon passes between Earth and the Sun, blocking the Sun's light from reaching Earth.
    • A total solar eclipse occurs when the Moon's umbra reaches Earth's surface.
    • An annular eclipse occurs when the Moon's umbra does not reach Earth's surface.
    • A total solar eclipse is only visible from the path of totality.

    Eclipse Seasons and Cycles

    • An eclipse season is the period of time when the Moon is near a node in its orbit, making eclipses possible.
    • The saros cycle is a period of 18 years, 111/3 days, after which the alignments of the Sun, Moon, and Earth are repeated, making eclipses predictable.

    Moon's Visibility

    • The phase of the Moon on a particular night is determined by the relative positions of the Sun, Earth, and Moon.
    • The Moon's visibility is affected by the Moon's distance from Earth and the position of the observer on Earth.
