And they all have elliptical orbits, even Earth. The statement by Junior "nearly circular" was quite wrong and by your numbers the orbits of a few of the others, while not crossing with other planets are also quite far from a circle.
Question:
If you drew the orbits of the first four planets on a standard, letter sized piece of paper with a sharp pencil and a circle-drawing compass -- would the true orbits lie within the width of the pencil line -- or fall outside the line width?
The eccentricity of our planet's orbit is mild; aphelion and perihelion differ from the mean Sun-Earth distance by less than 2%. In fact, if you drew Earth's orbit on a sheet of paper it would be difficult to distinguish from a perfect circle and that is with e = 0.0167.
