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. Mercury and Mars and others orbit it sun. That’s why it takes more to reach Mars. Take off at the wrong time and angle Mars will be on the opposite side of the sun and Mars takes 687 days to get to the same position
