according to keplers 2nd law, at which position will a planet move fastest in its orbit around the sun?
perigee (close point for orbits around earth)
apogee (far point for orbits around earth)
aphelion (far point in orbit)
planets move at the same speed at all points in their orbit.
perihelion (close point in orbit)

Explanation:

Kepler's 2nd Law (law of equal - areas) states that a line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time. This implies that the planet moves faster when it is closer to the Sun (perihelion) and slower when it is farther away (aphelion). Perigee and apogee are related to orbits around Earth, not the Sun. Planets do not move at the same speed at all points in their orbit.

Answer:

E. perihelion (close point in orbit)
