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.
But we can get an estimate of the number of atoms in the earth by first knowing what its mass is. The mass of an object is a measure of how much material the object has. The mass of the earth is 5.98*10 27 grams. That's the scientific way to write a large number that has a lot of zeros.
