Barnard's Star, showing position every 5 years in the period 1985–2005. The proper motion of Barnard's Star corresponds to a relative lateral speed of 90 km/s. The 10.3 arcseconds it travels in a year amount to a quarter of a degree in a human lifetime, roughly half the angular diameter of the full Moon. [16]
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.
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 ...
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.
A Texas state court authorised an emergency order allowing a pregnant woman to get an abortion — flying in the face of the state’s strict anti-abortion bans and the first case of its kind ...
The Texas Supreme Court has temporarily blocked a pregnant woman from obtaining an emergency abortion in a ruling issued late Friday. The court froze a lower court’s ruling that would have ...
