Ellipse
In space and astronautical engineering, an ellipse is a closed curve that is symmetrical about its major axis. It is a conic section, formed by the intersection of a plane and a cone. In space, the orbit of a planet or a satellite around another celestial body is an ellipse, with the body being located at one of the foci of the ellipse. The shape of the ellipse is determined by the eccentricity of the orbit, which is a measure of how much the orbit deviates from a perfect circle. The study of ellipses is important in space engineering, as it is necessary to calculate the trajectory of a spacecraft in order to ensure that it reaches its intended destination.
