Kepler’s third law states

The orbit of a planet around the sun is an ellipse, with the sun at one focus

The semimajor axis is equal to the planet’s average distance from the sun

The square of the orbital period of a planet is proportional to its orbital radius

None of these answers is correct

- 10. Multiple Choice30 seconds1 ptAccording to Kepler's 3rd law, the square of the time it takes for an object to orbit, T, is directly related to the cube of the distance, r, between the object and what it is orbiting.

What this means is that if a satellite moves away from what it is orbiting,the larger the constant k is.the smaller the constant k is.the longer the orbital period is.the shorter the orbital period is. - 11. Multiple Choice30 seconds1 pt

8T

$\frac{T}{8}$

2T

$\frac{T}{4}$
