Why moon is not visible today?
Just like the stars and planets, the Moon is not simply a nighttime object. It’s there during the daytime, too. One reason we can’t see the Moon during the day is because the Sun is so bright! As the Moon and Earth orbit, the Moon is only visible above the horizon roughly 12 hours out of every 24 hours.
Why does the moon change phases when viewed from Earth?
The phases we see result from the angle the Moon makes with the Sun as viewed from Earth. But the lit side does not always face the Earth! As the Moon circles the Earth, the amount of the lit side we see changes. These changes are known as the phases of the Moon and it repeats in a certain way over and over.
What causes the moon to appear larger when it is rising or setting?
