Question
Chapter 10, Problem 1VSC
To determine
The time is taken by the star and the planet to complete one orbit around their center of mass.
Expert Solution & Answer
Answer to Problem 1VSC
Solution:
The time taken is 5 days.
Explanation of Solution
Given data:
The below figure shows the periodic variations in the Doppler shift of a star caused by a planet orbiting around it. Positive velocities mean the star is moving away from the Earth and negative velocities mean that the star is moving towards Earth.
The orbital period for a planet detected by the Doppler method, the time between two points with the same velocity and slope in the velocity-time curve.
From the velocity-time graph, we find this time period to be 5 days.
Conclusion:
It takes 5 days for the star and the planet to complete one orbit around their center of mass.

Interplanetary Navigation. The most efficient way to send a spacecraft from the earth to another planet is by using a Hohmann transfer orbit (Fig. P13.87). If the orbits of the departure and destination planets are circular, the Hohmann transfer orbit is an elliptical orbit whose perihelion and aphelion are tangent to the orbits of the two planets. The rockets are fired briefly at the depar- ture planet to put the spacecraft into the transfer orbit; the spacecraft then coasts until it reaches the destination planet. The rockets are then fired again to put the spacecraft into the same orbit about the sun as the destination planet. (a) For a flight from earth to Mars, in what direction must the rockets be fired at the earth and at Mars: in the direction of motion, or opposite the direction of motion?
