  4. Orbital plane - Wikipedia

    en.wikipedia.org/wiki/Orbital_plane

    The orbital plane of a revolving body is the geometric plane in which its orbit lies. Three non- collinear points in space suffice to determine an orbital plane. A common example would be the positions of the centers of a massive body (host) and of an orbiting celestial body at two different times/points of its orbit.

  5. Longitude of the ascending node - Wikipedia

    en.wikipedia.org/wiki/Longitude_of_the_ascending...

    The reference plane is assumed to be the xy-plane, and the origin of longitude is taken to be the positive x-axis. k is the unit vector (0, 0, 1), which is the normal vector to the xy reference plane. For non-inclined orbits (with inclination equal to zero), ☊ is undefined.

  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. Orbital plane of reference - Wikipedia

    en.wikipedia.org/wiki/Orbital_plane_of_reference

    The plane tangent to celestial sphere for extrasolar objects; On the plane of reference, a zero-point must be defined from which the angles of longitude are measured. This is usually defined as the point on the celestial sphere where the plane crosses the prime hour circle (the hour circle occupied by the First Point of Aries), also known as ...

  8. Orbital elements - Wikipedia

    en.wikipedia.org/wiki/Orbital_elements

    K̂ is perpendicular to the reference plane. Orbital elements of bodies (planets, comets, asteroids, ...) in the Solar System usually the ecliptic as that plane. x̂, ŷ are in the orbital plane and with x̂ in the direction to the pericenter . ẑ is perpendicular to the plane of the orbit. ŷ is mutually perpendicular to x̂ and ẑ.

  9. Beta angle - Wikipedia

    en.wikipedia.org/wiki/Beta_angle

    Beta angle ()In orbital mechanics, the beta angle is the angle between a satellite's orbital plane around Earth and the geocentric position of the Sun. [1] The beta angle determines the percentage of time that a satellite in low Earth orbit (LEO) spends in direct sunlight, absorbing solar radiation. [2]
