When it entered the atmosphere on Jan. 18, the object was probably more than 20 feet wide and weighed 220 tons.

Also, objects in space don't weigh anything because there isn't any gravity.

A dense object weighs a lot for a given volume - steel or lead for example.

The object has the same mass, but weighs less in water due to this upward buoyant force acting on it.

These massive objects sometimes weighed several pounds, and with the addition of padding must have been unbearably hot.

The large, gear-shaped object surely weighed a couple hundred pounds.

Moving things around in space, where an object didn't weigh anything, sounded easy as breathing.

One effect is that an object weighs slightly less at the equator.

For example, when an object weighs 50 Kilograms, the measurement is true in the gravitational environment of planet earth.

So any object on the Moon weighs 1/6th of its weight on Earth.
