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.
by Jerry Coffey on February 18, 2009. The surface area of the Earth is 510 million square kilometers or 5.1Ã10 8 km 2. The Earth is a water heavy planet, so, if you break its surface area into water and land segments, it would look like this: land 149 million km 2, water 361 million km 2.
