Alien Planet is a 94-minute docufiction, originally airing on the Discovery Channel, about two internationally built robot probes searching for alien life on the fictional planet Darwin IV.
An astronomical object or celestial object is a naturally occurring physical entity, association, or structure that exists in the observable universe.
The barycenter (or barycentre; from the Ancient Greek βαρύς heavy + κέντρον centre) is the center of mass of two or more bodies that are orbiting each other, which is the point around which they both orbit.
A binary asteroid is a system of two asteroids orbiting their common barycenter.
A binary star is a star system consisting of two stars orbiting around their common barycenter.
A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it.
Brown dwarfs are substellar objects that occupy the mass range between the heaviest gas giant planets and the lightest stars, having masses between approximately 13 to 75–80 times that of Jupiter, or approximately to about.
Charon, also known as (134340) Pluto I, is the largest of the five known natural satellites of the dwarf planet Pluto.
In astronomy, a contact binary is a binary star system whose component stars are so close that they touch each other or have merged to share their gaseous envelopes.
A contact binary is a small Solar System body that is composed of two bodies that have gravitated toward each other until they touch.
Darwin IV is a fictional planet and the subject of Wayne Barlowe's book Expedition and the television special, Alien Planet, based on Expedition.
In astronomy, a double planet (also binary planet) is a binary system where both objects are of planetary mass.
An eclipse is an astronomical event that occurs when an astronomical object is temporarily obscured, either by passing into the shadow of another body or by having another body pass between it and the viewer.
A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter.
Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward (or gravitate toward) one another.
Invader Zim is an American animated television series created by Jhonen Vasquez for Nickelodeon.
The Karl Schwarzschild Observatory (Karl-Schwarzschild-Observatorium) is a German astronomical observatory in Tautenburg near Jena, Thuringia.
Mass Effect 2 is an action role-playing video game developed by BioWare and published by Electronic Arts.
The Milky Way is the galaxy that contains our Solar System.
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 minor-planet moon is an astronomical object that orbits a minor planet as its natural satellite.
A natural satellite or moon is, in the most common usage, an astronomical body that orbits a planet or minor planet (or sometimes another small Solar System body).
A neutron star is the collapsed core of a large star which before collapse had a total of between 10 and 29 solar masses.
In physics, an orbit is the gravitationally curved trajectory of an object, such as the trajectory of a planet around a star or a natural satellite around a planet.
A planet is an astronomical body orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity, is not massive enough to cause thermonuclear fusion, and has cleared its neighbouring region of planetesimals.
Pluto (minor planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond Neptune.
In astronomy, rotational Brownian motion is the random walk in orientation of a binary star's orbital plane, induced by gravitational perturbations from passing stars.
Space.com is a space and astronomy news website.
A star system or stellar system is a small number of stars that orbit each other, bound by gravitational attraction.
The Hitchhiker's Guide to the Galaxy is the first of five books in the Hitchhiker's Guide to the Galaxy comedy science fiction "trilogy" by Douglas Adams.
79360 Sila–Nunam, provisional designation, is a double cold classical Kuiper belt object (cubewano) with components of almost equal size, orbiting beyond Neptune in the Solar System.
90 Antiope is a double asteroid in the outer asteroid belt.
