Conic sections are important in astronomy: the orbits of two massive objects that interact according to Newton's law of universal gravitation are conic sections if their common center of mass is considered to be at rest. If they are bound together, they will both trace out ellipses; if they are moving apart, they will both follow parabolas or hyperbolas. See two-body problem. WebThe formula to find out the eccentricity of any conic section is defined as: Eccentricity, e = c/a Where, c = distance from the centre to the focus a = distance from the centre to the vertex For any conic section, the general equation is of the quadratic form: Ax 2 + Bxy + Cy 2 + Dx + Ey + F = 0
