  2. Barycenter (astronomy) - Wikipedia

    en.wikipedia.org/wiki/Barycenter_(astronomy)

    A barycenter is a dynamical point, not a physical object. It is an important concept in fields such as astronomy and astrophysics . The distance from a body's center of mass to the barycenter can be calculated as a two-body problem .

  3. Center of mass - Wikipedia

    en.wikipedia.org/wiki/Center_of_mass

    The barycenter is the point between two objects where they balance each other; it is the center of mass where two or more celestial bodies orbit each other. When a moon orbits a planet , or a planet orbits a star , both bodies are actually orbiting a point that lies away from the center of the primary (larger) body. [ 25 ]

  4. Barycentric coordinate system - Wikipedia

    en.wikipedia.org/wiki/Barycentric_coordinate_system

    Barycentric coordinates are strongly related to Cartesian coordinates and, more generally, affine coordinates.For a space of dimension n, these coordinate systems are defined relative to a point O, the origin, whose coordinates are zero, and n points , …,, whose coordinates are zero except that of index i that equals one.

  5. Two-body problem - Wikipedia

    en.wikipedia.org/wiki/Two-body_problem

    In classical mechanics, the two-body problem is to calculate and predict the motion of two massive bodies that are orbiting each other in space. The problem assumes that the two bodies are point particles that interact only with one another; the only force affecting each object arises from the other one, and all other objects are ignored.

  6. Astronomical coordinate systems - Wikipedia

    en.wikipedia.org/wiki/Astronomical_coordinate...

    The heliocentric ecliptic system describes the planets' orbital movement around the Sun, and centers on the barycenter of the Solar System (i.e. very close to the center of the Sun). The system is primarily used for computing the positions of planets and other Solar System bodies, as well as defining their orbital elements .

  7. Barycentric - Wikipedia

    en.wikipedia.org/wiki/Barycentric

    Barycenter or barycentre, the center of mass of two or more bodies that orbit each other; Barycentric coordinates, coordinates defined by the common center of mass of two or more bodies (see Barycenter) Barycentric Coordinate Time, a coordinate time standard in the Solar system; Barycentric Dynamical Time, a former time standard in the Solar System

  9. List of centroids - Wikipedia

    en.wikipedia.org/wiki/List_of_centroids

    The following is a list of centroids of various two-dimensional and three-dimensional objects. The centroid of an object in -dimensional space is the intersection of all hyperplanes that divide into two parts of equal moment about the hyperplane.
