Solar System Magnetopauses
| Planet | Number | Magnetic moment | Magnetopause distance | Observed size of the magnetosphere | variance of magnetosphere |
|---|---|---|---|---|---|
| Mercury | 1 | 0.0004 | 1.5 | 1.4 | 0 |
| Venus | 2 | 0 | 0 | 0 | 0 |
| Earth | 3 | 1 | 10 | 10 | 2 |
| Mars | 4 | 0 | 0 | 0 | 0 |
| Jupiter | 5 | 20000 | 42 | 75 | 25 |
| Saturn | 6 | 600 | 19 | 19 | 3 |
| Uranus | 7 | 50 | 25 | 18 | 0 |
| Neptune | 8 | 25 | 24 | 24.5 | 1.5 |
Research on the magnetopause is conducted using the LMN coordinate system (which is set of axes like XYZ). N points normal to the magnetopause outward to the magnetosheath, L lies along the projection of the dipole axis onto the magnetopause (positive northward), and M completes the triad by pointing dawnward.
Venus and Mars do not have a planetary magnetic field and do not have a magnetopause. The solar wind interacts with the planet’s atmosphere and a void is created behind the planet. In the case of the Earth’s moon and other bodies without a magnetic field or atmosphere, the body’s surface interacts with the solar wind and a void is created behind the body.

Famous quotes containing the words solar system, solar and/or system:
“Our civilization has decided ... that determining the guilt or innocence of men is a thing too important to be trusted to trained men.... When it wants a library catalogued, or the solar system discovered, or any trifle of that kind, it uses up its specialists. But when it wishes anything done which is really serious, it collects twelve of the ordinary men standing round. The same thing was done, if I remember right, by the Founder of Christianity.”
—Gilbert Keith Chesterton (1874–1936)

“I have no concern with any economic criticisms of the communist system; I cannot enquire into whether the abolition of private property is expedient or advantageous. But I am able to recognize that the psychological premises on which the system is based are an untenable illusion. In abolishing private property we deprive the human love of aggression of one of its instruments ... but we have in no way altered the differences in power and influence which are misused by aggressiveness.”
—Sigmund Freud (1856–1939)
