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.
Earth's mass is 6.580 sextillion tons according to the World Book of Facts 2003 edition. Mass and weight are different. Mass is the amount of matter in an object. Unlike weight, it is not affected by location. Weight is the effect of gravity on mass. Earth is increasing in mass by many thousands of tons daily by the daily accretion of extraterrestrial meteorites and meteor dust.
