Will everyone on this earth view the moon the same way given that they all are in different location?

Question

For example, if on the night of the 11th of this month, I stand out in my balcony at 10pm sharp (my time) and see a crescent shaped moon, will someone let's say in Africa or any other part of the world look at the same shape and size of the moon given that person also view it at exactly 10pm (their time) the same date?

Answer 1

Pretty much, yes. The phase of the moon depends on the moon's position in its orbit around the Earth. Even though 10pm in Africa may not be exactly the same time as 10pm where you are, the moon isn't going to change much in that time, as far as I know.

The only exception to this that I know would be during some new moons and full moons. If the moon is at a certain position between the Earth and the sun or on the other side of the earth, some parts of the world will see a lunar/solar eclipse, whereas you may see only a transiting moon or nothing at all. In that case, it absolutely depends where you are geographically, but for the most part the moon looks the same around the world.

Answer 2

The most time different between 10 pm your time and 10 pm somewhere else is 14 hours (it would be 12 hours if time zones were perfectly regular, but some of them have odd shapes). In 14 hours, the light / dark line on the moon moves about 7 degrees ( 4% of the moon's face). Somebody with good eyes and knowledge of lunar features would notice that much change.

Around the time of the new moon, the change is much easier to notice: at one time the moon is 100% dark, and a couple of hours later, there is a bright band at one edge.

Answer 3

Yes, all people in the world see the same phase of the Moon. But they all see it in different parts of the sky, just like the Sun is in different parts of the sky for people in different locations at the same moment. That is why we have time zones and why it can be midnight in China and noon in the United States at the same moment.
