This titled position of the earths axis is known as inclination of the earths axis. The earth's rotation axis makes an angle of about 66.5 degrees with the plane of its orbit around the sun, or about 23.5 degrees from the perpendicular to the ecliptic plane.
There is no 'periodic' change in the earths orbit. The orbit is elliptical and over time (a great many years) becomes less so.

That would be the "ecliptic plane".
No; it's about 23 degrees off the plane of its orbit.
Ecliptic.
No. For one thing, a plane is, by definition, 2-dimensional. The moon's orbit is tilted about 5 degrees relative to Earth's orbit.

Which orbit would that be? The galactic orbit, the solar orbit, the local cluster orbit? From what viewpoint? Above or below the galactic plane, the planetary system plane, from the point of view of a different place in the local cluster than on earth itself?
the earths orbit because the earths orbit is the size of earth + the size of the moon
The Earth's tilt, or inclination, or obliquity is about 23.44 degrees from the plane of its orbit around the Sun.
Earths Orbit? Earths Orbit?
The axis of the Earth is tilted 23.5 degress from the plane of the orbit round the sun.
Earths orbit around the sun is not unusual.
