A newly discovered planet orbits a distant star with the same mass as the Sun at an average distance of 128 million kilometers.
Its orbital eccentricity is 0.3. Find the planet's orbital period in months
1 answer:
The answer for this problem would be:
Orbital period if distance = 128,000,00 km and mass = Sun?
<span>This is approximately be .85 astronomical units if converted km to au.
</span>
We will be using Kepler's third law which is:
<span>T^2 = r^3 </span>
<span>T^2 = .85^3 </span>
<span>T^2 = .61
</span>
get the square root of .61
so the answer will be:
<span>T = .78 Years which is in months is 9.36 months.</span>
