According to Kepler's third law if planet a takes 12 years to travel around its star at a distance of three AU and how many years of planet be taken to orbit at a distance of 12 AU
Added by Lawrence T.
Step 1
Mathematically, this can be expressed as: \[ P^2 \propto a^3 \] or \[ \left(\frac{P_a}{P_b}\right)^2 = \left(\frac{a_a}{a_b}\right)^3 \] Show more…

An imaginary planet takes about 3 years to orbit the Sun. Based on Kepler's laws, what is the semi-major axis of its orbit (average distance from the Sun) in AU (astronomical units)?
Prabhu R.
Suppose you discover a planet around a Sun-like star. From careful observation over several decades, you find that its period is 12 Earth years. Find the semimajor axis.
