... these step by step below. It turns out that 51 Peg is about the same mass as the sun so to measure the semi-major axis, we can use Kepler’s 3rd Law (without Newton’s modification). If the period is measured in years, then we obtain the semi-major axis in A.U. from P2 = a3. a. Calculate the semi-majo ...
