path of moon and tilt
I've read that the moon tilt's is about 1.5 degrees on its axis.
Are the moon and earth on the same plane of revolution around the sun? It doesn't look like it from pics, but that may be just because of earth's 23 degree tilt. Are all the planets on the same plane of revolution? |

Dear Tim923:

It doesn't look like it from pics, but that may be just because of earth's 23 degree tilt. The Moon has a small wobble, and its axis of revolution is very close to perpendicular to its plane of orbit. Are all the planets on the same plane of revolution? No. Check out "Axial Tilt" for Uranus. http://nssdc.gsfc.nasa.gov/planetary...eet/index.html David A. Smith |

The Moon has a small wobble, and its axis of revolution is very close to perpendicular to its plane of orbit. Which in turn is inclined about 5° to the ecliptic. Are all the planets on the same plane of revolution? No. Check out "Axial Tilt" for Uranus. http://nssdc.gsfc.nasa.gov/planetary...eet/index.html That's rotation about its axis, not revolution around the Sun. Uranus's orbital inclination (found two rows above axal tilt in the table) is very similar to the Earth's. The orbits of all the major (non-dwarf) planets lie within about 5° of a common plane; Mercury's orbit is the most inclined to the Earth's, at 7°, all the other inclinations being less than half of that. -- Odysseus |
