What phase of the moon is most difficult to see during the day?
New Moon. New moons are very difficult to see because a new moon is always closest to the sun. In other words, the sun isn’t shining on the moon from Earth’s perspective. That’s what makes it so hard to see a new moon.
What does not affect the moon’s phases?
Which of the following phenomena never affects the moon’s phase? The moon’s orbit around the earth. A lunar eclipse occurs during all full moons. A lunar eclipse can only occur during a full moon.
What affects the moon’s phases?

What is the phases of the moon in order?
When sunlight reflects off the near side, we call it a full Moon. The rest of the month we see parts of the daytime side of the Moon, or phases. These eight phases are, in order, new Moon, waxing crescent, first quarter, waxing gibbous, full Moon, waning gibbous, third quarter and waning crescent.
What is the darkest moon phase?
The moment a thin sliver of the Moon becomes visible after New Moon is the beginning of the first intermediate phase, the Waxing Crescent Moon. In the past, this used to be called New Moon while the darkest phase was called Dark Moon.
What is the first quarter moon phase?
First quarter: The moon is 90 degrees away from the sun in the sky and is half-illuminated from our point of view. We call it “first quarter” because the moon has traveled about a quarter of the way around Earth since the new moon. Waxing gibbous: The area of illumination continues to increase.
Which definition of Umbra is most accurate?
Astronomy. the complete or perfect shadow of an opaque body, as a planet, where the direct light from the source of illumination is completely cut off. Compare penumbra (def. 1a). the dark central portion of a sunspot.
Why can you only see half the Moon?
Only one side of the Moon is visible from Earth because the Moon rotates on its axis at the same rate that the Moon orbits the Earth—a situation known as synchronous rotation, or tidal locking. The Moon is directly illuminated by the Sun, and the cyclically varying viewing conditions cause the lunar phases.
