An ellipse is a geometric shape which looks like a squashed circle into an oval shape. We can have vertical ellipse and horizontal ellipse in the alt code system also black and white. Ellipses are known in physics, astronomy, and engineering.
The orbit of every planet in our solar system is approximately an ellipse with the Sun at the center. The same thing is right for moons orbiting other planets. The shapes of planets and stars in our solar system are often well represented by an ellipsoid. If you look at a circle from a side angle, it will seem like an ellipse.
