Ellipse - batman logo
The x-axis would be considered the major axis meaning that the vertices and foci lay on this axis. The center can be found right in the middle of the bat, where the major and minor axes intersect.

Hyperbola-Internet
A hyperbola is two parabolas opening in opposite directions with the formula
(x^2/a^2)-(y^2/b^2)=1 if the parabolas open left and right or the formula
(y^2/a^2)-(x^2/b^2)=1

The shape of the crater is an ellipse.
When the "a^2" value is under the "x^2", the major axis is on the x-axis. When the "a^2" value is under the "y^2 value, the major axis is on the y-axis
