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.
The mass of Earth is 5.97 x 10 24 kg. Here that is written out: 5,970,000,000,000,000,000,000,000 kg. Yeah, thatâs a really big number. And yet, itâs only 0.3% the mass of Jupiter (and Jupiter is mostly lightweight hydrogen).We have written many articles about Earth for Universe Today.Hereâs an article about how fast Earth rotates, and hereâs an article about Earthâs magnetic field.he mass of Earth is 5.97 x 10 24 kg.
