Question
Chapter 3, Problem 1QAP
To determine
The given is statement is correct or incorrect.
Expert Solution & Answer
Answer to Problem 1QAP
The given statement is true.
Explanation of Solution
The motion of a planet around the sun is given by Kepler in his 3 laws of planetary motion. Each law defines different aspect of the motion of planet.
The Kepler’s first law defines the shape of orbit of a planet around the Sun.
According to Kepler’s 1st law, the planet orbits around the sun in an elliptical path. The sun is located at the one focus of the ellipse and other focus is a point in empty space.
Conclusion:
Thus, the Kepler’s laws explain why the planets orbits the Sun as they do.

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.
The period of revolution of the planet Saturn is approximately 29.5 years. Calculate the distance to the sun. Using Kepler's laws
Which of the following are, or follow directly from, Kepler's Laws of planetary motion? Check all that apply.
More distant planets move at slower speeds.
The force of attraction between any two objects decreases with the square of the distance between their centers.
The orbit of each planet about the Sun is an ellipse with the Sun at one focus.
A planet travels faster when it is nearer to the Sun and slower when it is farther from the Sun.
As a planet moves around its orbit, it sweeps out equal areas in equal times.
