According to Kepler's second law,an object in an elliptical orbit around the Sun is traveling fastest when it is at what position?
A) Because it travels at a constant speed throughout its orbit,there is no such position.
B) When it is approaching the Sun,because attraction is greatest over this region
C) Aphelion,farthest from the Sun,because it has to move farther per day at that position
D) Perihelion,the closest point to the Sun

According to Kepler's second law, an object in an elliptical orbit around the Sun travels fastest when it is at the closest point to the Sun, which is called perihelion. This is because at perihelion, the object is closer to the Sun and thus experiences a stronger gravitational force, causing it to move faster.
