How did we land back on earth from the moon

Question

Wouldn’t when we land on the moon, the earth would still be in motion bc of the orbit, and so whenever we exit the orbit of the moon (Which was orbiting the earth) the earth would still be in a constant orbit moving at high speeds, how did we calculate and intercept earth in said orbit.

Answer 1

The Moon orbits the Earth, so it’s not like the Earth is leaving the Moon behind. When a spacecraft lands on the Moon or orbits the Moon, it’s still orbiting the Earth because it’s “attached” to the Moon, which is still orbiting the Earth. All you have to do is burn your engines in the right direction so that your trajectory send you back to Earth.
