What is Orbital Obliquity ?
Obliquity relates to a planet’s plane of orbit. As an orbiting planet spins on its axis, obliquity is the angle between a perpendicular to its orbital plane and its spin axis – the tilt of its axis.
What is Orbital Eccentricity?
Eccentricity measures how much the shape of Earth’s orbit departs from a perfect circle.
