The major axis of an ellipse is its longest diameter, a line that runs through the centre and both foci, its ends being at the widest points of the shape.
The semi-major axis is one half of the major axis, and thus runs from the centre, through a focus, and to the edge of the ellipse.
It is often said that the semi-major axis is the "average" distance between the primary (the focus of the ellipse) and the orbiting body.

  semi-major axis
Half the longest distance (major axis) across an ellipse.
The semi-major axis is one of the orbital elements – a standard parameter used to describe an elliptical orbit.
The semimajor axis is also the average distance of an orbiting object from its primary.

The orbital and axial planes are not precisely aligned: Earth's axis is tilted some 23.5 degrees against the Earth-Sun plane (which causes the seasons), and the Earth-Moon plane is tilted about 5 degrees against the Earth-Sun plane (otherwise there would be an eclipse every month).
If Earth's axis of rotation were to approach the plane of the ecliptic, extremely severe weather could result as one pole was continually heated and the other cooled.
In science fiction the Earth is frequently the capital or a major administrative center of a hypothetical galactic government (especially when that galactic government is postulated to be human -dominated), often a representative federal republic, though empires and dictatorships are definitely not unseen.

The scale of an axis is the units into which the axis is divided.
The scale of a value axis is more complex because you have to choose minimum and maximum axis values and determine where the divisions between the maximum and minimum should fall.
Major Divisions shows the number of major divisions into which you want to divide the values that fall between Maximum and Minimum.

It may seem curious that the inclination of the lunar orbit and the tilt of the Moon's axis of rotation are listed as varying considerably.
One must be reminded here that the orbital inclination is measured with respect to the primary's equatorial plane (in this case the Earth's), and that the axis of rotation's tilt is measured with respect to the normal to the satellite's orbital plane (the Moon's).
The plane of the lunar orbit maintains an inclination of 5.145 396° with respect to the ecliptic (the orbital plane of the Earth), and the lunar axis of rotation maintains an inclination of 1.5424° with respect to the normal to that same plane.

If it is an ellipse, the major axis is the longest diameter, while the minor axis is the shortest.
The semi-major axis is half the major axis, in km or mi.
These points (the foci) are not centered in the ellipse, so the semi-major axis does not directly describe the altitude at perigee.

An ellipse is (sort of) an oval shape, with two interior points called foci (singular: focus), a long axis (the major axis), a short axis (the minor axis), and a center (which should under no circumstances be confused with a focus).
Half of the major axis is called the semi-major axis, and the semi-major axis is also the average sun-planet distance.
These points are on the major axis, as are both foci and the center.

Fetch the major axis (the axis the children are tiled along).
This is implemented to mark the major axis as having changed so that a future check to see if the requirements need to be published to the parent view will consider the major axis.
Since the major axis is updated asynchronously and should be the sum of the tiled children the call is ignored for the major axis.
