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).
Annibale de Gasparis (November 9, 1819, Bugnara – March 21, 1892, Naples) was an Italian astronomer, born in Bugnara to parents originally from Tocco da Casauria.
Arizona State University (commonly referred to as ASU or Arizona State) is a public metropolitan research university on five campuses across the Phoenix metropolitan area, and four regional learning centers throughout Arizona.
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.
An asteroid spectral type is assigned to asteroids based on their emission spectrum, color, and sometimes albedo (reflectivity).
The astronomical unit (symbol: au, ua, or AU) is a unit of length, roughly the distance from Earth to the Sun.
In astronomy, axial tilt, also known as obliquity, is the angle between an object's rotational axis and its orbital axis, or, equivalently, the angle between its equatorial plane and orbital plane.
In the field of astronomy the term chord typically refers to a line crossing an object which is formed during an occultation event.
Cupid and Psyche is a story originally from Metamorphoses (also called The Golden Ass), written in the 2nd century AD by Lucius Apuleius Madaurensis (or Platonicus).
NASA's Discovery Program is a series of lower-cost (as compared to New Frontiers or Flagship Programs), highly focused American scientific space missions that are exploring the Solar System.
The ecliptic coordinate system is a celestial coordinate system commonly used for representing the apparent positions and orbits of Solar System objects.
Giga is a unit prefix in the metric system denoting a factor of a (short-form) billion (109 or 000).
In orbital mechanics and aerospace engineering, a gravitational slingshot, gravity assist maneuver, or swing-by is the use of the relative movement (e.g. orbit around the Sun) and gravity of a planet or other astronomical object to alter the path and speed of a spacecraft, typically to save propellant and reduce expense.
Greek mythology is the body of myths and teachings that belong to the ancient Greeks, concerning their gods and heroes, the nature of the world, and the origins and significance of their own cult and ritual practices.
An hour (symbol: h; also abbreviated hr.) is a unit of time conventionally reckoned as of a day and scientifically reckoned as 3,599–3,601 seconds, depending on conditions.
A hydroxy or hydroxyl group is the entity with the formula OH.
Infrared radiation (IR) is electromagnetic radiation (EMR) with longer wavelengths than those of visible light, and is therefore generally invisible to the human eye (although IR at wavelengths up to 1050 nm from specially pulsed lasers can be seen by humans under certain conditions). It is sometimes called infrared light.
The Infrared Astronomical Satellite (IRAS) was the first-ever space telescope to perform a survey of the entire night sky at infrared wavelengths.
Iron is a chemical element with symbol Fe (from ferrum) and atomic number 26.
James Ferguson (August 31, 1797 – September 26, 1867) was a Scottish-born American astronomer and engineer, who made the first discovery of an asteroid from North America (31 Euphrosyne).
Johann Franz Encke (23 September 1791 – 26 August 1865) was a German astronomer.
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.
In astronomy, a light curve is a graph of light intensity of a celestial object or region, as a function of time.
Lindy Elkins-Tanton is a planetary scientist with expertise in planet formation and evolution.
M-type asteroids are asteroids of partially known composition; they are moderately bright (albedo 0.1–0.2).
Mass is both a property of a physical body and a measure of its resistance to acceleration (a change in its state of motion) when a net force is applied.
The Mauna Kea Observatories (MKO) are a number of independent astronomical research facilities and large telescope observatories that are located at the summit of Mauna Kea on the Big Island of Hawaiʻi, United States.
Mesosiderites are a class of stony–iron meteorites consisting of about equal parts of metallic nickel-iron and silicate.
Naples (Napoli, Napule or; Neapolis; lit) is the regional capital of Campania and the third-largest municipality in Italy after Rome and Milan.
The NASA Infrared Telescope Facility (NASA IRTF) is a telescope optimized for use in infrared astronomy and located at the Mauna Kea Observatory in Hawaii.
Nickel is a chemical element with symbol Ni and atomic number 28.
An occultation is an event that occurs when one object is hidden by another object that passes between it and the observer.
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.
The planetary core consists of the innermost layer(s) of a planet; which may be composed of solid and liquid layers.
In planetary science, planetary differentiation is the process of separating out different constituents of a planetary body as a consequence of their physical or chemical behaviour, where the body develops into compositionally distinct layers; the denser materials of a planet sink to the center, while less dense materials rise to the surface, generally in a magma ocean.
A protoplanet is a large planetary embryo that originated within a protoplanetary disc and has undergone internal melting to produce a differentiated interior.
Psyche is a planned orbiter mission that will explore the origin of planetary cores by studying the metallic asteroid.
The pyroxenes (commonly abbreviated to Px) are a group of important rock-forming inosilicate minerals found in many igneous and metamorphic rocks.
Radar astronomy is a technique of observing nearby astronomical objects by reflecting microwaves off target objects and analyzing the reflections.
Rheasilvia is the most prominent surface feature on the asteroid Vesta and is thought to be an impact crater.
In chemistry, a silicate is any member of a family of anions consisting of silicon and oxygen, usually with the general formula, where 0 ≤ x Silicate anions are often large polymeric molecules with an extense variety of structures, including chains and rings (as in polymeric metasilicate), double chains (as in, and sheets (as in. In geology and astronomy, the term silicate is used to mean silicate minerals, ionic solids with silicate anions; as well as rock types that consist predominantly of such minerals. In that context, the term also includes the non-ionic compound silicon dioxide (silica, quartz), which would correspond to x.
Stony-iron meteorites or siderolites are meteorites that consist of nearly equal parts of meteoric iron and silicates.
