According to Kepler's second law, there is nothing at the other focus of the ellipse. The law states that a planet or comet orbiting the Sun will sweep out equal areas in equal times, meaning that the object will move faster when it is closer to the Sun and slower when it is farther away. Because the orbit is elliptical, the object will speed up as it gets closer to the Sun and slow down as it moves away. The focus of the ellipse where the Sun is located is not the center of the ellipse, but rather one of the foci. The other focus does not have any physical object at its location.
