In first order the magnetic field created by this magnet is that of a dipole whose axis is tilted with respect to the spin axis by about 11 degrees. ... The difference between the dipole axis and geographic axis is one of the reasons why there are so many different coordinate systems needed to describe locations in space around the Earth. The area around the Earth governed by its magnetic field is called the magnetosphere . ...

... Jupiter is our Solar System?s very own superhero. The giant planet is two and a half times more massive than all the rest of the planets in our Solar System combined. And with great mass, comes great gravity. With the power of super-strong gravity, Jupiter plays a heroic role in our Solar System, protecting life on Earth. ... Unfortunately, we have found lots of solar systems with massive planets that lie close to their star, but not so many that lie far away, like Jupiter. ...

... One possible application of a solar sail is a spacecraft to warn Earth of approaching interplanetary disturbances and shocks. ... Spacecraft that can provide such a warning are currently stationed at (or near) the Lagrangian L1 point , between the Earth and the Sun--at about 4 times the distance of the moon and 1/100 times that of the Sun. ... Because of the greater distance from Earth, the Earth's pull there is weaker, not enough to make the spacecraft match the Earth's motion around the Sun. ...
