circular
linear
towards the focal point
elliptical

Solution
The orbit of a planet revolving around a star is elliptical.
Explanation:
The planet’s distance from the star changes as it follows an elliptical path (so orbits are not perfectly circular). Because of this, the planet moves faster when it is nearer the star and slower when it is farther away (Kepler’s second law).

To verify Kepler's third law graphically four students plotted graphs. Student A plotted a graph of T (period of revolution of planets) versus r (average distance of planets from the sun) and found the plot is straight line with slope 1.85. Student B plotted a graph of T2 v/s r3 and found the plot is straight line with slope 1.39 and negative Y-intercept. Student C plotted graph of log T v/s log r and found the plot is straight line with slope 1.5. Student D plotted graph of log T v/s log r and found the plot is straight line with slope 0.67 and with negative X-intercept. The correct graph is of student
