Strangely, âposhliâ (which means âletâs goâ or âletâs head outâ in Russian) is actually the past tense of the verb meaning âTo head off on foot.â In other words, âposhliâ literally means, âWe (or they) headed off on foot.â How can a word which is in the past tense indicate the desire to head off somewhere now?
The Hill sphere, or gravitational sphere of influence, of Earth is about 1.5 Gm or 1,500,000 km in radius. This is the maximum distance at which the Earth's gravitational influence is stronger than the more distant Sun and planets.
The Earth's mass is 5.9736 x 1024 kilograms. That, we can say with assurance. It's not so easy to say what the Earth's weight is, because the weight of any mass depends on what else is nearby. Most people have heard by now that a 200-pound man weighs only 33.1 pounds on the Moon.
