Solar and Lunar Eclipses All about shadows

What is an Eclipse? An astronomical event that occurs when one celestial object (Earth or moon) moves into the shadow of another

2 Types of Eclipses 1-Solar 2-Lunar

What is a Solar Eclipse? Sun’s light is blocked by the Moon Moon’s shadow on Earth Sun, Moon and Earth are in line

Moon’s Shadow on Earth Solar Eclipse

68) A Solar eclipse occurs only during which phase of the moon 68) A Solar eclipse occurs only during which phase of the moon? New Moon

What is a Lunar Eclipse? Sun’s light is blocked by the Earth Earth’s shadow on Moon Sun, Earth and Moon are in line

Earth’s Shadow on Moon Lunar Eclipse During a Lunar Eclipse the Sun turns the Moon blood red!

69) A Lunar eclipse occurs only during which phase of the moon 69) A Lunar eclipse occurs only during which phase of the moon? Full Moon

Why doesn’t a lunar eclipse occur every month during the full moon?

Moon Stats Moon’s orbit around Earth is inclined about 5 degrees to Earth’s plane of orbit around the Sun Ecliptic plane Moon’s orbital plane Moon Earth Sun Moon’s orbit around the Earth is elliptical: ~0.15% out of circular. Tilted by 5º from the Ecliptic. Mean Distance: 384,400 km Perigee (Closest Approach): 363,300 km Apogee (Maximum Distance): 405,500 km Appears ~11% larger at Perigee than at Apogee Understanding this is fundamental to understanding why eclipses do not happen every month, or getting the reason for phases confused with eclipses.

70) Why doesn’t a lunar eclipse occur every month during the full moon  70) Why doesn’t a lunar eclipse occur every month during the full moon? The moon’s orbit around the Earth is at a slight tilt compared to the Earth’s orbit around the sun. The Earth is not directly between the Sun and the moon during every Full Moon phase.

Why doesn’t a solar eclipse occur every month during the new moon?
