For example, the Star does not have the 1911's grip safety. In addition, the thumb safety on the Star BM blocks the hammer, whereas it blocks the motion of the sear on a 1911 and the Star's trigger pivots on a roll pin rather than moving straight back like a 1911A1's trigger to trip the sear. The pistol is fed by an 8-round detachable box magazine.
Barnard's Star's transverse speed is 90 km/s and its radial velocity is 111 km/s (perpendicular (at a right, 90° angle), which gives a true or "space" motion of 142 km/s. True or absolute motion is more difficult to measure than the proper motion, because the true transverse velocity involves the product of the proper motion times the distance.
Barnard's Star is a small red dwarf star in the constellation of Ophiuchus.At a distance of 5.96 light-years (1.83 pc) from Earth, it is the fourth-nearest-known individual star to the Sun after the three components of the Alpha Centauri system, and is the closest star in the northern celestial hemisphere.

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 ...
Barnard's Star is a very low-mass star in the constellation Ophiuchus. In 1916, American astronomer E. E. 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 .

The Star Model B is a single-action semi-automatic pistol that fires the 9 mm Parabellum pistol cartridge. It was produced by Star Bonifacio Echeverria, S.A. in Spain as a derivative of the Star Model A in 9x23mm Largo. It is visually similar to and inspired by the M1911 series 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 ...
