Slower or faster than what? - When the Earth is nearer the Sun (periapsis), it moves faster than when it is farther away from the Sun (apapsis).
earth's elliptical orbit around the sun causes the changes. (science fact: as earth gets closer to the sun, it goes faster.) look up on Google images of "earth's orbit and seasons"
earth's orbit is elliptical with sun at its focus. when earth reach near to it ,earth travel faster and when far away its slower . therefore answer will depend on the which month you are considering. acc. to kleepner law area swept in a particular time is same.
If the satellite is at the perigee it would go faster and if it was at the apogee it would go slower.
Mars has the most elliptical orbit. The earth's is almost a perfect circle
The Earth has an elliptical orbit around the Sun.
Mars takes longer to make one orbit of the sun. Its slower, and it also has further to go. Planets orbiting speeds get slower the further you go out.

Yes, it does.
Elliptical.

ALL orbits are elliptical.
