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?

by Jerry Coffey on March 8, 2009. The size of Earth, like the size of all of the celestial bodies, is measured in a number of parameters including mass, volume, density, surface area, and equatorial/polar/mean diameter.While we live on this planet, very few people can quote you the figures for these parameters.Below is a table with many of the pieces of the data used to measure the size of the Earth.arth orbits with a perihelion of 147,098,290 km, and an aphelion of 152,098,232 km, making for a semi-major axis of 149,598,261 km. Even though we need oxygen to survive, it is the second most abundant component of Earthâs atmosphere. Nitrogen accounts for 78% of the gases in the atmosphere and oxygen occupies 21%.
