Saturn orbits the sun at a distance of 1.43 × 1012 m. the mass of the sun is 1.99 × 1030 kg.
use to determine saturn’s orbital period in earth years. is it:
a)29.6 earth years
b)296 earth years
c)874 earth years

Saturn’s orbital period is 29.6 years

Step-by-step explanation:

It is given that,

The mass of the sun, m = 1.99 × 10³⁰ kg

Saturn orbits the sun at a distance of, a = 1.43 × 10¹² m

Using third law of Kepler's :

Where,

T is the orbital time period

G is the universal gravitational constant

M is the mass of the sun

a is the distance

So,

To convert seconds into year divide the time by 3.154 × 10⁷

So, T = 29.55 Years

or T = 29.6 Years

Hence, the Saturn's orbital period is 29.6 Earth years
