In recent years, astronomers have found planets orbiting nearby stars that are quite different from planets in our solar system. Kepler-12b, has a diameter that is 1.7 times that of Jupiter (RJupiter = 6.99 × 10^7 m), but a mass that is only 0.43 that of Jupiter (MJupiter = 1.90 × 10^27 kg ).

Answer:

The acceleration due to gravity is 3.86 m/s^2.

Explanation:

Radius , R  = 1.7 x 6.99 x 10^7 m

mass, M = 0.43 x 1.9 x 10^27 kg

The acceleration due to gravity is given by

[tex]g= \frac{GM}{R^2}\\\\g =\frac{6.67\times 10^{-11}\times 0.43\times 1.9\times 10^{27}}{(1.7\times 6.99\times 10^7)^2}\\\\g = 3.86 m/s^2[/tex]
