Ecliptic.
No; it's about 23 degrees off the plane of its orbit.
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?
It is called the "ecliptic plane"
The plane of Earth's orbit is known as the ecliptic. It is the flat plane in space that represents the path along which the Earth travels around the Sun. The ecliptic is inclined at an angle of approximately 23.5 degrees to the celestial equator.
The planets don't all orbit the Sun in EXACTLY the same plane - there are small variations. The plane where Earth orbits is called the Ecliptic; other planets orbit fairly close to that same plane.
The Earth's tilt, or inclination, or obliquity is about 23.44 degrees from the plane of its orbit around the Sun.
The axis of the Earth is tilted 23.5 degress from the plane of the orbit round the sun.
Uranus is the planet whose axis of rotation is almost perpendicular to the plane of its orbit around the Sun. This unique orientation of its axis causes extreme seasons on Uranus, with each pole experiencing 42 years of continuous sunlight followed by 42 years of darkness.
False
legends a plane would be called the xy-plane if it had the x and y points on it Y axis
