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:
“The solar system has no anxiety about its reputation, and the credit of truth and honesty is as safe; nor have I any fear that a skeptical bias can be given by leaning hard on the sides of fate, of practical power, or of trade, which the doctrine of Faith cannot down-weigh.”
—Ralph Waldo Emerson (1803–1882)
“Senta: These boats, sir, what are they for?
Hamar: They are solar boats for Pharaoh to use after his death. They’re the means by which Pharaoh will journey across the skies with the sun, with the god Horus. Each day they will sail from east to west, and each night Pharaoh will return to the east by the river which runs underneath the earth.”
—William Faulkner (1897–1962)
“Science is a system of statements based on direct experience, and controlled by experimental verification. Verification in science is not, however, of single statements but of the entire system or a sub-system of such statements.”
—Rudolf Carnap (1891–1970)
