Earth travels in an orbit as it revolves earths axis is always tilted in the same direction?

Answer 1

No ONE direction ALWAYS. The direction of the Earth's axis changes over the eons. The pattern that the axis draws on the celestial sphere is roughly circular (the precession) making one revolution about every 23000 years but there are small dips too (nutations) which complicate matters.

Right now the axis points almost towards the star we call Polaris (it pointed closes sometime in 2007). in 11000 years it will point close to the star we now call Vega.

Earth's axis of rotation is precessing, so that the direction in which the north pole points is tracing a circle in the sky. But that's happening so slowly that during the course of a person's lifetime, it appears to point permanently toward the same spot. That spot is presently very close to the star called Polaris ... the 'North Star'.

Answer 2

The earth's axis always points to the same distant point in the sky. (Well, actually it changes slowly

over thousands of years, but we're ignoring that slow change for right now.)

So, as I was saying, the earth's axis always points to the same distant point in the sky, and

that direction is not perpendicular to the plane of our path around the sun . That means that

when we're on one side of the sun, the top of the axis is tilted toward the sun, and when we're

on the other side of the sun, the top of the axis is tilted away from the sun.

Answer 3

Yes, Earth revolves around the sun in an elliptical orbit, and its axis is tilted at approximately 23.5 degrees. This tilt is responsible for the changing seasons as different parts of the Earth receive varying amounts of sunlight throughout the year.

Answer 4

Yes. The rotational axis makes an angle of about 66.5 degrees with the orbital plane.

For some reason, a lot of people feel that it should naturally be 90 degrees.
