  2. Star Walk - Wikipedia

    en.wikipedia.org/wiki/Star_Walk

    The application aims to determine the position of celestial objects in the sky, calculated in real-time based on the position of the user. It includes information on star clusters , meteor showers , iridium flares , galaxies , and nebulae as well as the current position of dwarf planets , comets , asteroids , and man-made satellites .

  3. Poles of astronomical bodies - Wikipedia

    en.wikipedia.org/wiki/Poles_of_astronomical_bodies

    The poles of astronomical bodies are determined based on their axis of rotation in relation to the celestial poles of the celestial sphere. Astronomical bodies include stars, planets, dwarf planets and small Solar System bodies such as comets and minor planets (e.g., asteroids), as well as natural satellites and minor-planet moons.

  4. Astronomical coordinate systems - Wikipedia

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

    In astronomy, coordinate systems are used for specifying positions of celestial objects (satellites, planets, stars, galaxies, etc.) relative to a given reference frame, based on physical reference points available to a situated observer (e.g. the true horizon and north to an observer on Earth's surface).

  6. Orrery - Wikipedia

    en.wikipedia.org/wiki/Orrery

    A small orrery showing Earth and the inner planets. An orrery is a mechanical model of the Solar System that illustrates or predicts the relative positions and motions of the planets and moons, usually according to the heliocentric model. It may also represent the relative sizes of these bodies; however, since accurate scaling is often not ...

  7. List of multiplanetary systems - Wikipedia

    en.wikipedia.org/wiki/List_of_multiplanetary_systems

    The table below contains information about the coordinates, spectral and physical properties, and the number of confirmed (unconfirmed) planets for systems with at least 2 planets and 1 not confirmed. The two most important stellar properties are mass and metallicity because they determine how these planetary systems form. Systems with higher ...
