Node is the term used to describe the point in a comet's orbit where it crosses the plane of Earth's orbit.

Semi-major axis is the term used to describe the distance between a comet's perihelion and aphelion.

Orbital period is the term used to describe the time it takes for a comet to complete one orbit around the Sun.
