Inclination of the axis
There are two standard methods of specifying a planet's tilt. One way is based on the planet's north pole, defined in relation to the direction of Earth's north pole, and the other way is based on the planet's positive pole, defined by the right-hand rule: The International Astronomical Union (IAU) defines the north pole of a … See more In astronomy, axial tilt, also known as obliquity, is the angle between an object's rotational axis and its orbital axis, which is the line perpendicular to its orbital plane; equivalently, it is the angle between its equatorial plane … See more Earth's orbital plane is known as the ecliptic plane, and Earth's tilt is known to astronomers as the obliquity of the ecliptic, being the angle between the ecliptic and the See more The stellar obliquity ψs, i.e. the axial tilt of a star with respect to the orbital plane of one of its planets, has been determined for only a few systems. … See more • National Space Science Data Center • Seidelmann, P.

The portions of the fold between adjacent axes form the flanks, limbs, or slopes of a fold. An anticline is a fold that is convex upward, and a syncline is a fold that is concave upward.
