Can helium escape earth's atmosphere
WebFeb 5, 2012 · The Earth’s core loses energy, since much of it is consumed in a planet’s lifespan, but that only accounts for a loss for about 16 metric tons per year. The biggest mass loss comes from escaped hydrogen and helium, which escape with 95,000 metric tons of mass and 1,600 metric tons respectively. http://scienceline.ucsb.edu/getkey.php?key=2
