Albedo
Albedo (albedo, meaning "whiteness") is the measure of the diffuse reflection of solar radiation out of the total solar radiation received by an astronomical body (e.g. a planet like Earth).

Asteroid
Asteroids are minor planets, especially those of the inner Solar System.

Asteroid belt
The asteroid belt is the circumstellar disc in the Solar System located roughly between the orbits of the planets Mars and Jupiter.

Asteroid family
An asteroid family is a population of asteroids that share similar proper orbital elements, such as semimajor axis, eccentricity, and orbital inclination.

Asteroid spectral types
An asteroid spectral type is assigned to asteroids based on their emission spectrum, color, and sometimes albedo (reflectivity).

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

C-type asteroid
C-type (carbonaceous) asteroids are the most common variety, forming around 75% of known asteroids.

Degree (angle)
A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle, defined so that a full rotation is 360 degrees.

Digitized Sky Survey
The Digitized Sky Survey (DSS) is a digital version of several photographic atlases of the night sky, and an ongoing project to produce more digital versions of photographic astronomical datasets.

Ecliptic
The ecliptic is the circular path on the celestial sphere that the Sun follows over the course of a year; it is the basis of the ecliptic coordinate system.

Hans Rosenthal
Hans Rosenthal (2 April 1925 – 10 February 1987) was a radio editor, director, and one of the most popular German radio and television hosts of the 1970s and 1980s.

Kirkwood gap
A Kirkwood gap is a gap or dip in the distribution of the semi-major axes (or equivalently of the orbital periods) of the orbits of main-belt asteroids.

Minor planet
A minor planet is an astronomical object in direct orbit around the Sun (or more broadly, any star with a planetary system) that is neither a planet nor exclusively classified as a comet.

Minor Planet Center
The Minor Planet Center (MPC) is the official worldwide organization in charge of collecting observational data for minor planets (such as asteroids and comets), calculating their orbits and publishing this information via the Minor Planet Circulars.

Observation arc
In observational astronomy, an observation arc (or arc length) is the time period between the first and most recent (last) observation, tracing the body's path.

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.

Poles of astronomical bodies
The poles of astronomical bodies are determined based on their axis of rotation in relation to the celestial poles of the celestial sphere.

Precovery
In astronomy, precovery (short for pre-discovery recovery) is the process of finding the image of an object in old archived images or photographic plates for the purpose of calculating a more accurate orbit.

Rotation period
In astronomy, the rotation period of a celestial object is the time that it takes to complete one revolution around its axis of rotation relative to the background stars.

S-type asteroid
S-type asteroids are asteroids with a spectral type that is indicative of a silicaceous (i.e. stony) mineralogical composition, hence the name.

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.
