What are the two lengths that all ellipses have (all planets)?

a. minor and major axes
b. horizontal and vertical length
c. conic and isoconic length
d. x and y axes

Option A

Explanation:  

All the planets are elliptical in shape.There are two axes found in any ellipse of all the planets. The largest diameter in the ellipse is called as the major axis of the ellipse.

The shortest diameter of the ellipse is called as the minor axis. These two lengths are found in every planets of the universe.

Option (A)

Explanation:

Generally, an ellipse is defined as a plane curve that borders any two focal points in such a way that for all of its points lies on the curve and the sum of the two distances to their focal points must remain constant.

The shape of most of the planets usually resembles an ellipse, which is basically comprised of two axes, which represents the diameters of the ellipse. Of the two, one is the longest and the other is the smallest, that forms the major and the minor axes respectively. They are always oriented perpendicular to each other.

When both of these axes are equal in terms of length then the ellipse represents a circle.

Thus, the correct answer is option (A).

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.
