That's the "ecliptic plane".
The earths orbit around the sun is almost circular.
The satellites of Uranus revolve around the planet in planes almost perpendicular to its orbit.
Orbit
No. The moon's orbit around the earth is.
no
Orbit
The geometric plane that contains the earth's orbit around the sun and the geometric plane that contains the moon's orbit around the earth are not the same plane. The plane of the moon's orbit is tilted compared with the plane of earth's orbit. If the two planes were co-planar (if they overlapped perfectly) then there would be a lunar eclipse every month.
Yes.
The annual orbit of Earth around the sun is known as a year.
The Earth's journey around the sun is called its orbit.
The Earth's orbit is almost circular. Technically, the "eccentricity" of the orbit is about 0.0167.
Something that goes around the Earth
