Problem 12.4: Determine the mass of the star
Please wait for the animation to completely load.
A planet has an initial velocity in the y direction that gives it a slightly elliptical orbit around a star as shown in the animation (position is given in 106 km and time is given in years). Restart.
- Determine the mass of the star.
- What is the correct orbital radius to give circular motion? Drag the planet at t = 0 to determine this radius. You may also drag the gray blocks around to use them as temporary or permanent markers.
