Jupiter's four large moons -- Io, Europa, Ganymede, and Callisto -- were discovered by Galileo in 1610. Jupiter also has dozens of smaller moons. Callisto has a radius of about 2.40 106 m, and the mean distance between Callisto and Jupiter is 1.88 109 m. (a) If Callisto's orbit were circular, how many days would it take Callisto to complete one full revolution around Jupiter

Respuesta :

You would use  

P^2 = (2π)^2(D^3)/((G)(M))  

where P is the orbital period in seconds, D is the distance in meters, M is the mass in kilograms of Jupiter, and G is the 6.67 x 10^ -11 m^3/ kg sec^2  

M Jupiter = 1.9 x 10^27 kg, D = 1.88 x10^9 meters  

P^2 = 39.5*(6.65 x 10^27)/(( 6.67 x 10^ -11)(1.9 x 10^27)) = 2.07 x 10^12  

P = 1,440,000 seconds = 16.66 days

Jupiter is the largest planet in the solar system that have four large natural satellites, Ganymede, Callisto, and Europa.

Given that:

Distance = 1.88 x 10⁹ m

Mass = 1.9 x 10²⁷ kg

Radius = 2.40 x 10⁶ m

Gravitational constant = 6.67 x 10⁻¹¹ m³ kg/ sec²

Now,

From the formula of orbital periods, it can be calculated as:

P² = [tex]\dfrac{(2 \pi^2) (D^3)}{GM}[/tex]

Substituting the values in the above formula:

P² = [tex]\dfrac{39.5 \times 6.65 \times 10 ^{27}}{(6.67 \times 10^{-11}) (1.9 \times 10^{27})}\\\\[/tex]

P² = [tex]2.07 \times 10^{12}[/tex]

P = 14440000 seconds or approximately 16.66 days.

Thus, the Callisto will require 16.66 days to orbit around the planet.
