WebEccentricity defines how circular the orbit is; if e =0, the two foci overlap and the ellipse is a circle. Second Law A given planet covers the same area of space in the same amount of time, regardless of orbit location. In the above image, SP is the line from the sun to the planet. Sector velocity is the rate at which the area A is swept out. landscaping side of house with no windowsWebMachholz 1 has a very elliptical shape due to the higher eccentricity.
