Absolute magnitude is a measure of the luminosity of a celestial object, on a logarithmic astronomical magnitude scale.
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).
Asteroids are minor planets, especially those of the inner Solar System.
The asteroid belt is the circumstellar disc in the Solar System located roughly between the orbits of the planets Mars and Jupiter.
An asteroid family is a population of asteroids that share similar proper orbital elements, such as semimajor axis, eccentricity, and orbital inclination.
The astronomical unit (symbol: au, ua, or AU) is a unit of length, roughly the distance from Earth to the Sun.
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.
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.
Eucrites are achondritic stony meteorites, many of which originate from the surface of the asteroid 4 Vesta and as such are part of the HED meteorite clan.
The European Southern Observatory (ESO) is a 15-nation intergovernmental research organization for ground-based astronomy.
The Flora or Florian '''family''' of asteroids is a large grouping of S-type asteroids in the inner main belt, whose origin and properties are relatively poorly understood at present.
Giovanni de Sanctis (born 1949) is an Italian astronomer and discoverer of minor planets at the Osservatorio Astronomico di Torino (Astronomical Observatory of Turin) in Turin, Italy.
Henri Debehogne (30 December 1928 – 9 December 2007) was a Belgian astronomer and a prolific discoverer of minor planets.
An impact crater is an approximately circular depression in the surface of a planet, moon, or other solid body in the Solar System or elsewhere, formed by the hypervelocity impact of a smaller body.
The Jet Propulsion Laboratory (JPL) is a federally funded research and development center and NASA field center in Pasadena, California, United States, with large portions of the campus in La Cañada Flintridge, California.
Julian day is the continuous count of days since the beginning of the Julian Period and is used primarily by astronomers.
In astronomy, a Julian year (symbol: a) is a unit of measurement of time defined as exactly 365.25 days of SI seconds each.
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.
La Silla Observatory is an astronomical observatory in Chile with three telescopes built and operated by the European Southern Observatory (ESO).
In astronomy, a light curve is a graph of light intensity of a celestial object or region, as a function of time.
In astronomy, magnitude is a logarithmic measure of the brightness of an object in a defined passband, often in the visible or infrared spectrum, but sometimes across all wavelengths.
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.
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.
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.
The Observatory of Turin (Osservatorio Astronomico di Torino, also known as Pino Torinese; obs. code: 022) is an astronomical observatory owned and operated by Italy's National Institute for Astrophysics (Istituto Nazionale di Astrofisica, INAF).
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 elements are the parameters required to uniquely identify a specific orbit.
Orbital inclination measures the tilt of an object's orbit around a celestial body.
Palomar Observatory is an astronomical observatory located in San Diego County, California, United States, southeast of Los Angeles, California, in the Palomar Mountain Range.
In meteoritics, a parent body is the celestial body from which originates a meteorite or a class of meteorites.
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.
The proper orbital elements of an orbit are constants of motion of an object in space that remain practically unchanged over an astronomically long timescale.
Rheasilvia is the most prominent surface feature on the asteroid Vesta and is thought to be an impact crater.
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 asteroids are asteroids with a spectral type that is indicative of a silicaceous (i.e. stony) mineralogical composition, hence the name.
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.
The Vesta or Vestian family of asteroids is a large and prominent grouping of mostly V-type asteroids ("vestoids") in the inner asteroid belt in the vicinity of 4 Vesta.
Wide-field Infrared Survey Explorer (WISE) is a NASA infrared-wavelength astronomical space telescope launched in December 2009, and placed in hibernation in February 2011.
Wiesław Z. Wiśniewski (May 2, 1931 in Poland – February 28, 1994 in Tucson, Arizona, United States) was a Polish astronomer.
Vesta, minor-planet designation 4 Vesta, is one of the largest objects in the asteroid belt, with a mean diameter of.
