Objects closer to Earth than the L1 point are controlled by Earth's gravity. Objects beyond the L1 point are controlled by the Sun. When J002E3 came close to the L1 point in April 2002, the object passed throuhgh L1--like a portal--from a Sun-orbit to an Earth-orbit.
In the top 20km of the Earth's crust, the conditions are right to produce a nearly inexhaustible supply of hydrogen, said Prof Freund. Studies by the team of common rock types such as granite and olivine have revealed extraordinarily high levels of trapped hydrogen.
So, how many Earths can fit in the Sun? The answer is that it would take 1.3 million Earths to fill up the Sun. Thatâs a lot of Earths. The Sun makes up 99.86% of the mass of the Solar System. And itâs the giant planets like Jupiter and Saturn which make the most of that remaining .14% of the Solar System.
