Pluto's distance P(t)(in billions of kilometers) from the sun as a function of time t (in years) can be modeled by a sinusoidal expression of the form a.sin(b.t)d
At year t=0, Pluto is at its average distance from the sun, which is 6.9 billion kilometers. In 66 years, it is at its closest point to the sun, which is 4.4 billion kilometers away.
