WebNow for the intermediate case: what about a planet with v escape = 8 km/s and a gas with v average = 2 km/s? In this case, v escape is comparable to 4-6v average (8-12 km/s). This means that the fastest few molecules will escape. Once they escape, a few other molecules will find there way to higher speeds and then they will escape.

Web24 jul. 2013 · New Horizons’ nominal trajectory will bring the spacecraft to within ~10,000 km of Pluto’s surface and ignoring the slight fact that there are uncertainties in deriving Pluto’s size in the 20-100 km range and ignoring whether you determine a planet size by including or excluding the atmosphere, there is a possibility New Horizons could be flying … Web13 apr. 2024 · Exp: Statement 1 is correct: The height of the troposphere at the poles is about 8 km, while at the equator it is about 16 km. This is because there is greater heating at the equator. Its thickness tends to vary seasonally. Heat differential on the planet’s surface causes convection currents to flow from the equator to the poles.
