Astronomers discovered an object in the outer Solar System with a semimajor axis of 577 AU. What is its orbital period?
Its orbital period is how many years.
This can be determined with the help of Kepler's 3rd law which suggests that, T2=a3
Given, a3= 577 AU, we have to determine T2,
So, T2=a3, T2= (8.32)3, (8.32)2= (8.32)3, 69.22= 577
So the orbital time period is 8.32 years.
