Pluto’s orbit is more eccentric than any of the major planets. what does that mean?

Explanation:

Eccentricity -

Eccentricity is a measure , that how an orbit deviates from a circular shape .

A perfect circular orbit , has an eccentricity value equal to zero .

And more the value of eccentricity , more elliptical is the path of the orbit .

Planets - Venus , Earth , Neptune in the  Solar System are the most elliptical , hence , Have the least eccentricity value .

And ,

Pluto , in the solar system have more eccentricity value .

The value of eccentricity of Pluto is 0.248 .
