Moon Phases SG

Moon Phases

the different appearances of the Moon as it orbits Earth, caused by the varying amounts of its sunlit surface visible from our planet

Rotation

the action of rotating around an axis or center

Revolution

an instance of revolving.

Lunar calender

a timekeeping system that bases its months on the cycles of the Moon's phases

Moon’s Orbit

the path an object follows when orbiting the Earth's Moon, not the Moon's orbit around Earth

Solar Eclipse

occurs when the moon passes between the sun and Earth, blocking the sun's light and casting a shadow on Earth

Lunar Eclipse

occurs when the Earth passes between the Sun and Moon, casting its shadow on the Moon and causing it to appear darker or sometimes even reddish

Earth’s Atmosphere

the layer of air surrounding our planet, composed primarily of gases like nitrogen and oxygen, that provides breathable air, shields us from harmful radiation, and regulates Earth's temperature

Umbra

the fully shaded inner region of a shadow cast by an opaque object, especially the area on the earth or moon experiencing the total phase of an eclipse.

Penumbra

the partially shaded outer region of the shadow cast by an opaque object.

Waxing

(of the moon between new and full) have a progressively larger part of its visible surface illuminated, increasing its apparent size.

Waning

(of the moon) have a progressively smaller part of its visible surface illuminated, so that it appears to decrease in size

Gibbous

(of the moon) having the observable illuminated part greater than a semicircle and less than a circle.

Crescent

the curved sickle shape of the waxing or waning moon.

New Moon

the phase of the moon when it is in conjunction with the sun and invisible from earth, or shortly thereafter when it appears as a slender crescent.

Full Moon

a lunar phase where the entire face of the moon appears illuminated from Earth, occurring when the Earth is positioned between the Sun and the Moon, causing the lunar hemisphere facing us to be fully sunlit

First Quarter Moon

a primary lunar phase where half of the Moon's face appears illuminated, occurring roughly one week after the New Moon, and is also known as a "half moon"

Third Quarter Moon

the Moon has completed 3/4 of its orbit around the Earth

Ray

each of the lines in which light (and heat) may seem to stream from the sun or any luminous body, or pass through a small opening

Crater

a large, bowl-shaped cavity in the ground or on the surface of a planet or the moon, typically one caused by an explosion or the impact of a meteorite or other celestial body.

Maria

a large, level basalt plain on the surface of the moon, appearing dark by contrast with highland areas.

Meteoroid

a small body moving in the solar system that would become a meteor if it entered the earth's atmosphere.
