Albert Einstein (14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics).
Aluminium or aluminum is a chemical element with symbol Al and atomic number 13.
Asteroids are minor planets, especially those of the inner Solar System.
The Aten asteroids are a dynamical group of asteroids whose orbits bring them into proximity with Earth.
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.
DANEOPS, the DLR-Archenhold Near Earth Objects Precovery Survey, has been initiated to systematically search existing photographic plate archives for precovery images of known NEOs.
An extinct comet is a comet that has expelled most of its volatile ice and has little left to form a tail and coma.
General relativity (GR, also known as the general theory of relativity or GTR) is the geometric theory of gravitation published by Albert Einstein in 1915 and the current description of gravitation in modern physics.
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.
The JPL Small-Body Database (SBDB) is an astronomy database about small Solar System bodies.
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.
Lead is a chemical element with symbol Pb (from the Latin plumbum) and atomic number 82.
The Lincoln Near-Earth Asteroid Research (LINEAR) project is a collaboration of the United States Air Force, NASA, and the MIT's Lincoln Laboratory for the systematic detection and tracking of near-Earth objects.
An Earth-crosser is a near-Earth asteroid whose orbit crosses that of Earth as observed from the ecliptic pole of Earth's orbit.
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.
A Venus-crosser is an asteroid whose orbit crosses that of Venus.
Mercury is the smallest and innermost planet in the Solar System.
The National Aeronautics and Space Administration (NASA) is an independent agency of the executive branch of the United States federal government responsible for the civilian space program, as well as aeronautics and aerospace research.
A near-Earth object (NEO) is any small Solar System body whose orbit can bring it into proximity with Earth.
Zinc is a chemical element with symbol Zn and atomic number 30.
