Astronomical unit
The astronomical unit (symbol: au, ua, or AU) is a unit of length, roughly the distance from Earth to the Sun.

Comet
A comet is an icy small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process called outgassing.

Comet Shoemaker–Levy 9
Comet Shoemaker–Levy 9 (formally designated D/1993 F2) was a comet that broke apart in July 1992 and collided with Jupiter in July 1994, providing the first direct observation of an extraterrestrial collision of Solar System objects.

Orbital eccentricity
The orbital eccentricity of an astronomical object is a parameter that determines the amount by which its orbit around another body deviates from a perfect circle.

Orbital inclination
Orbital inclination measures the tilt of an object's orbit around a celestial body.
New!!: Quasi-Hilda comet and Orbital inclination · See more »
Orbital resonance
In celestial mechanics, an orbital resonance occurs when orbiting bodies exert a regular, periodic gravitational influence on each other, usually because their orbital periods are related by a ratio of small integers.

Perihelion and aphelion
The perihelion of any orbit of a celestial body about the Sun is the point where the body comes nearest to the Sun.

Perturbation (astronomy)
In astronomy, perturbation is the complex motion of a massive body subject to forces other than the gravitational attraction of a single other massive body.

Semi-major and semi-minor axes
In geometry, the major axis of an ellipse is its longest diameter: a line segment that runs through the center and both foci, with ends at the widest points of the perimeter.
