How does the eccentricity of a typical cometary orbit compare to that of a typical planet

Explanation:

Comets are balls of ice and dust in orbit around the Sun. The orbits of comets are different from those of planets - they are elliptical. A comet's orbit takes it very close to the Sun and then far away again.

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.
