Within the boundary of the Earth is a collection of four interdependent parts called “spheres“: the lithosphere, hydrosphere, biosphere, and atmosphere.

Earth shows phases, just like the Moon does for terrestrial observers. The phases, however, are opposite; when the terrestrial observer sees the full Moon, the lunar observer sees a “new Earth”, and vice versa.

You don’t see the earth spinning from earth because it spins at 360 degrees per day. It’s just too slow for you to notice.

While the Moon’s gravity has acted as a brake on Earth’s rotation over time, our Earth still spins merrily away in the lunar sky every 24 hours. Earth’s phases are complementary to those of the Moon: when the Moon is new (from an earthling’s perspective), would-be Lunarians see a full Earth.

Tidal forces from Earth have slowed the Moon’s rotation to the point where the same side is always facing the Earth—a phenomenon called tidal locking. The other face, most of which is never visible from the Earth, is therefore called the “far side of the Moon”.

The answer is somewhat simple: The moon and stars are always somewhere in the sky, but we can’t always see them. Then, halfway through its orbit, the moon is “behind” the Earth with respect to the sun, and we can see the entire surface lit by the sun. This is what’s known as a full moon, but it’s visible only at night.

Yes, everyone sees the same phases of the Moon. People north and south of the equator do see the Moon’s current phase from different angles, though.

Some people think a moon visible in the west after sunset is a rising moon. It’s not; it’s a setting moon. As Earth spins under the sky, all sky objects rise in the east and set in the west. Such a moon lies not opposite the sun, but, on the contrary, on nearly the same line of sight to the sun, as seen from Earth.

The ‘dark side’ of the Moon refers to the hemisphere of the Moon that is facing away from the Earth. In reality it is no darker than any other part of the Moon’s surface as sunlight does in fact fall equally on all sides of the Moon.
