From a science perspective...

I weigh 170lbs. Lbs. is a unit of force. This means that standing on Earth, the Earth's gravity puts 170lbs. of force on me.

You take the moons distance, 238,000 miles, and its mass and the Universal gravitation constant and plug it into the equation F=GMm/(r^2) and then convert to lbs...

When I am standing on Earth the moon exerts a force of 0.000535 lbs. on me.

Because the other planets are much further, their gravitational effects are much smaller.
