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 × 107 m), but a mass that is only 0.43 that of jupiter (mjupiter = 1.90 × 1027 kg ).

g= 3.86 m/s^2

Explanation:

given : Kepler-12b, has a diameter that is 1.7 times that of Jupiter (R_Jupiter = 6.99 × 10^7 m), but a mass that is only 0.43 that of Jupiter (M_Jupiter = 1.90 × 10^27 kg ).

to calculate gravity we use the formula

g = GM/r^2

g = 6.67×10^-11 × 0.43×1.9×10^27/( 1.7×6.99×10^7)^2

g = 3.859 ~ 3.86 m/s^2

glen is correct.

step-by-step explanation:

glen is correct because when you multiply 4 * 2 = 8.

and 4 * 3 = 12.
