Which of the following statements describe a characteristic of the solar system that is explained by Kepler’s secondlaw? Select ALL that apply.A) Earth is slightly closer to the Sun on one side of its orbitthan on the other side.B) Pluto moves faster when it is closer to the Sun than whenit is farther from the Sun.C) Venus orbits the Sun faster than Earth orbits the Sun.D) All the planets orbit the Sun in nearly the same plane.E) The Sun is located slightly off-center from the middle ofeach planet’s orbit.F) Inner planets orbit the Sun at higher speed than outerplanets.
Kepler's 1st law says that our Solar System's planets orbit in ellipses around the Sun where the closest distance to the Sun is called perihelion. Suppose I tell you that there is a planet with a perihelion distance of 2 AU and a semi-major axis of 1.5 AU. Does this make physical sense? Explain why or why not.
A comet orbits a star with a highly eccentric elliptical orbit. At its nearest point, the comet is going a certain speed. Calculate the speed (in m/s) at its farthest point. • Nearest speed = 68 km/s • Closest point = 0.4 AU • Farthest point = 13,000 AU The comet's mass = 100,000 kg
