Passage
Read the passage given below and answer the questions that follows:
The orbit of Pluto is much more eccentric than the orbits of the other planets. That is, instead of being nearly circular, the orbit is noticeably elliptical. The point in the orbit nearest to the sun is called the perihelion and the point farthest from the sun is called the aphelion.
Orbit of Pluto - Perihelion and the Aphelion
In above figure we shows that the perihelion and the aphelion of the Pluto’s orbit.
