The Four Conics by Eccentricity Circle (e=0) Ellipse (0<e<1) Parabola (e=1) Hyperbola (e>1) All four conics form a single family distinguished only by eccentricity: a circle is the most "closed" (e=0), an ellipse is an elongated closed curve, a parabola is the borderline open curve (e=1), and a hyperbola has two separate open branches (e>1).
