"..that if you could see Jupiter's magnetic field from Earth, it would appear five times larger than the full moon?"

How can you say size of magnetic field..? Is it just getting weaker not ending like a wall? 195.163.176.146 05:15, 11 May 2007

the field is considered to end when the magnetic force at that point becomes too less to affect any nearby objects significantly...think so...
