What is so unusual about Pluto's orbit?
A. It's orbital period is exactly twice that of Neptune's.
B. It has an unexpectedly short orbital period.
C. It lies exactly on the ecliptic.
D. It has the lowest eccentricity of any planet's orbit.
E. It is more inclined to the ecliptic than any of the eight planets.

Answer 1

Answer:

Option E

Explanation:

• The path of the Pluto is not in line with the rest of the eight planets of our solar system whereas it is more inclined, i.e., inclination of $17^{\circ}$ to the ecliptic.
• The orbit of the pluto is more elliptical and more oval in shape than any other planet as a result of the cooling and refreezing of the gases.

Ecliptic:

It is a term used for the imaginary path of the sun annually.

It also represents the line along which the occurrence of the eclipses take place.
