Why is the moon dark during a lunar eclipse?
During a lunar eclipse, the moon appears dark because it moves into the Earth's shadow, blocking sunlight from reaching it. This causes the moon to temporarily lose its brightness and appear dark.
Why do moons appear to have different shape?
Earth's moon appears to have a different shape as it progresses through lunar phases each month due to the amount of sunlight hitting it.
Would lunar eclipses happen if earth were larger?
yes
Will a full earth illuminate the lunar landscape more than a full moon will illuminate the surface of the earth?
The Earth will illuminate the lunar landscape more, for two reasons: a) Earth has a larger surface area. b) Earth has a larger albedo, meaning that it reflects a larger percentage of the sunlight.
Would the lunar eclipses happen if earth were largerexplain?
Yes, they would be a little more common than they are. A lunar eclipse happens when the Moon goes into the shadow of the Earth. If the Earth was larger, the Earth's shadow would also be larger. For some times when the Moon currently just misses the Earth's shadow, if the Earth (and its shadow) were larger, the Moon wouldn't miss.
When does the new moon appear?
The new moon appears when the Moon is situated between the Earth and the Sun, making the side of the Moon that is illuminated by the Sun facing away from the Earth. This results in the Moon appearing dark in the sky, as it is not reflecting any sunlight towards Earth. The new moon marks the start of a new lunar cycle.
What is the lunar perigee?
The side of the orbit of the moon that is closest to the Earth is the lunar perigee.
Why is the umbra during a lunar eclipse larger than during a solar eclipse?
The umbra of the Earth's shadow during lunar eclipse is larger than the umbra of the Moon's shadow during a solar eclipse because the Earth is much larger than the Moon is; so, the Earth's shadow is bigger than the Moon's shadow.
What is the difference between a solar eclipse and lunar eclipse?
Solar eclipse is when the Moon passes between the Sun and Earth (The three objects would appear in this order: Sun >> Moon >> Earth). A lunar eclipse is when the Moon pass into the shadow of the Earth ( The three objects would appear in this order: Sun >> Earth >> Moon ).
Is the earth a stationary object in the lunar sky?
No, it is not. This will seem wrong to people who are aware that the moon's orbit it tidally locked with earth. Observed over a long enough period, the moon has a distinct wobble that comes from what is called libration. It results from the fact that the moon's orbital velocity around the earth is not constant, while the moon's rotational velocity is for all practical purposes constant. So the earth will appear to move a bit in the lunar sky. This is an apparent motion and not a true motion. It occurs to me that there must be places on the moon where the earth would appear, over the course of a lunar cycle, unable to decide whether to rise or to set! It would appear to bob up and down at the moon's horizon.
Does the earth look bright when it is seen from the moon?
From the surface of the Moon, the Earth appears substantially larger than the full moon does from Earth. This would be expected since the Earth's diameter is 4 times that of the Moon. Also, the Earth is always in the lunar sky for the one-half of the Moon that faces Earth, and is never visible from the opposite side. It would always appear to be in almost exactly the same place. It only appears to "rise and set" along a small strip between the two faces of the Moon.The brightness would vary with the phases, which would be exactly the opposite of the concurrent phase of the Moon: when the Moon is Full, the Earth is new, and vice versa. However, the Earth would be outshone by the Sun for the 14 days of lunar "daylight" in which the Sun and Earth are both always in the sky. This would make the Earth nearly invisible when it was close to the Sun.
What is it when the moon appears to be red?
This happens during a lunar eclipse when the earth appears apparently blocking out the moon. This can only happen on a full moon and due to this effect, the moon appears to be red.
