WebIn astronomy, the plane of the Sun's apparent orbit relative to the Earth is known as the ecliptic plane. Let us define non-rotating Cartesian coordinates, centered on the Earth, which are such that the - and -axes lie in the ecliptic plane, and the -axis is normal to this plane (in the sense that the Earth's north pole lies at positive ). green world pro cleanersWebWhat is earth tipped toward? The simple answer is Polaris. The axis (one end of it) points at Polaris, so that's what it's tipped to point at. But when we saw "toward" what do we mean? When it is tipped "toward" one thing, what is it being tipped "away from"? If earth were not tipped then the equator would lie in the same plane as earth's orbit. green world patio furniture
