When we say a planet has a high eccentric Orbit we mean?
Eccentricity is the measure of how much an object’s orbit deviates from a perfect circle. The higher the eccentricity, the more elliptical (oval) the orbit is. All planets orbit the sun in elliptical orbits (which means the sun is at one focus of the ellipse). But for highly-eccentric orbits, the sun is farther from the centre of the ellipse and farther from the other focus than in less-eccentric orbits. Since all orbits are elliptical, every planet is closest to the sun at one point in its orbit (called perihelion) and farthest from the sun (called aphelion) at the opposite point in its orbit.
