major axis
Longest elliptical line
The major axis is the longest diameter of an ellipse, passing through both foci and the center.
In planetary orbits, it determines the orbit's overall size and helps calculate orbital period.
The perpendicular shorter diameter is the minor axis.
The comet's major axis spans nearly twice the distance from Earth to the sun.
