  2. Barnard's Star - Wikipedia

    en.wikipedia.org/wiki/Barnard's_Star

    The radial velocity of Barnard's Star is −110 km/s, as measured from the blueshift due to its motion toward the Sun. Combined with its proper motion and distance, this gives a "space velocity" (actual speed relative to the Sun) of 142.6 ± 0.2 km/s. Barnard's Star will make its closest approach to the Sun around 11,800 CE, when it will ...

  3. Proper motion - Wikipedia

    en.wikipedia.org/wiki/Proper_motion

    Barnard's Star has the largest proper motion of all stars, moving at 10.3″ yr −1. Large proper motion usually strongly indicates an object is close to the Sun. This is so for Barnard's Star, about 6 light-years away. After the Sun and the Alpha Centauri system, it is the nearest known star.

    en.wikipedia.org/wiki/Portal:Outer_space/...

    Barnard measured its proper motion to 10.3 arcseconds per year, which remains the largest known proper motion of any star relative to the Sun. Lying at a distance of about 1.8 parsecs or 5.96 light-years , Barnard's Star is the second closest known star system to the Sun and the fourth closest known individual star after the three components of ...

  5. List of high-proper-motion stars - Wikipedia

    en.wikipedia.org/wiki/List_of_high-proper-motion...

    There is no specific velocity that is considered high, but the proper motion article notes that the majority of stars have a proper motion of 0.01 arc-seconds per year. Note that the closer a star is to earth, the faster it will appear to travel in arc-seconds per year for a given "real" velocity; therefore, the PM values here are apparent ...

    Barnard's Star, showing position every 5 years in the period 1985–2005.Barnard's Star is the star with the highest proper motion. [1]In astronomy, stellar kinematics is the observational study or measurement of the kinematics or motions of stars through space.

  8. List of nearest stars - Wikipedia

    en.wikipedia.org/wiki/List_of_nearest_stars

    Over long periods of time, the slow independent motion of stars change in both relative position and in their distance from the observer. This can cause other currently distant stars to fall within a stated range, which may be readily calculated and predicted using accurate astrometric measurements of parallax and total proper motions , along ...
