Haystack Observatory is an astronomical observatory owned by Massachusetts Institute of Technology (MIT).
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.
In Greek mythology, Icarus (the Latin spelling, conventionally adopted in English; Ἴκαρος, Íkaros, Etruscan: Vikare) is the son of the master craftsman Daedalus, the creator of the Labyrinth.
Icarus is a lunar impact crater that lies on the Moon's far side.
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.
The John F. Kennedy Space Center (KSC) is one of ten National Aeronautics and Space Administration field centers.
In astronomy, a light curve is a graph of light intensity of a celestial object or region, as a function of time.
This is a list of fast rotators—minor planets that have an exceptionally short rotation period, also called "rotation rate" or "spin rate".
A Mars-crossing asteroid (MCA, also Mars-crosser, MC) is an asteroid whose orbit crosses that of Mars.
A Mercury crosser is an asteroid whose orbit crosses that of Mercury.
This is a list of all astronomers who are credited by the Minor Planet Center (MPC) with the discovery of one or several minor planets.
A Venus-crosser is an asteroid whose orbit crosses that of Venus.
Lunar distance (LD or \Delta_), also called Earth–Moon distance, Earth–Moon characteristic distance, or distance to the Moon, is a unit of measure in astronomy.
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.
The Massachusetts Institute of Technology (MIT) is a private research university located in Cambridge, Massachusetts, United States.
Mercury is the smallest and innermost planet in the Solar System.
Meteor is a 1979 Hong Kong–American science fiction disaster film in which scientists detect an asteroid on a collision course with Earth and struggle with international, Cold War politics in their efforts to prevent disaster.
A meteor shower is a celestial event in which a number of meteors are observed to radiate, or originate, from one point in the night sky.
Minimum orbit intersection distance (MOID) is a measure used in astronomy to assess potential close approaches and collision risks between astronomical objects.
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.
A minute of arc, arcminute (arcmin), arc minute, or minute arc is a unit of angular measurement equal to of one degree.
A near-Earth object (NEO) is any small Solar System body whose orbit can bring it into proximity with Earth.
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 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 measures the tilt of an object's orbit around a celestial body.
