To estimate the mass of the Sun, we can use Kepler's Third Law of planetary motion, which relates the orbital radius and the period of revolution of a planet around the Sun. Here’s a step-by-step solution: ### Step 1: Identify the given data - Mean orbital radius of the Earth around the Sun, \( r = 1.5 \times 10^8 \) km - Convert this radius into meters: \[ r = 1.5 \times 10^8 \text{ km} = 1.5 \times 10^{11} \text{ m} \] ...
