Just for fun I got the orbit numerical information for 2020 of the Earth and Mars from the JPL (Jet propulsion Laboratory).

Then did some processing and graphed the result in 3D with a 7-day step. The blue line/dots correspond to the Earth. Red for Mars. Green for the vector from Earth to Mars.

It is quite visually obvious that the eccentricity of the Mars orbit is much bigger (a bit over x5 in fact) than that of the Earth’s orbit.
