Question

What is an example of Kepler's third law

Answer 1

1. Kepler's third law states that the square of the time period of revolution of a planet around the sun in an elliptical orbit is directly proportional to the cube of its semi-major axis.
   ${\mathrm{T}}^2\propto {\mathrm{a}}^3$
   where, $\mathrm{T}$ is the time period of revolution of a planet around the sun and $\mathrm{a}$is the semi-major axis of the elliptical orbit
2. According to Kepler's third law, the period of a planet's orbit around the Sun grows fast as the radius of its orbit increases.
3. As a result, we discover that Mercury, the innermost planet, orbits the Sun in only 88 days.
4. The earth takes 365 days to orbit the sun, while Saturn takes 10,759 days.
5. Kepler's third law offers a precise explanation of the duration and size of a planet's orbit around the sun.
6. They may also be used to describe how moons circle a planet.
7. They may be used to describe any exoplanet's orbits around any star, not only those in our solar system.
