That's the definition of an ellipse.
An ellipse does not have parallel lines in the traditional sense, as it is a smooth, closed curve defined by its geometric properties. However, one can draw tangents to the ellipse at various points, and some of these tangents can be parallel to each other. In a broader mathematical context, while the ellipse itself does not possess parallel lines, the concept of parallelism can apply to lines related to the ellipse, such as its axes or tangents.
In the context of an ellipse, each point marked with a dot is called a "focus" or "foci" (plural). The ellipse has two foci, which are positioned symmetrically along the major axis. These points are crucial in defining the shape and properties of the ellipse, as they relate to the distances from any point on the ellipse to the foci.
Yes the ratios are sometimes equal to each other.

You construct a Hexagon by drawing 8 lines that touch each other.
An oval is an ellipse
The shape of the orbit of each planet is an ellipse. An ellipse is a geometric shape that is like a flattened circle. The Sun is located at one of the foci of the ellipse, not at the center.

Johannes Kepler discovered that the Earth revolves/orbits the Sun in an ELLIPSE. He also discovered that the Sun is NOT at the centre of the ellipse, but at one of the foci ; (plural of focus). The other focal point being 'blind'. From this we have the definition, that as the Earth orbits the Sun , 'It sweeps equal arcs in equal times'. As the Earth orbits, it speeds up and slows down. It is moving at its fastest when passing the Sun at it nearest point ( perigee) and slowest when at its furthest point ( apogee). Have a look in Wikipedia under' Johannes Kepler.

An eclipse occurs when one celestial body blocks the light from another, like a solar or lunar eclipse. An ellipse is a geometric shape that resembles an elongated circle, often used to describe the shape of orbits of planets and other celestial bodies.
