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.
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 ...
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 ...
Basically, it gives officials the ability to temporarily close roads and change traffic patterns — like making a two-lane, two-way road one way — as needed. Wayne County has issued a state of ...
Edward Emerson Barnard / ˈ b ɑːr n ər d / (December 16, 1857 – February 6, 1923) was an American astronomer. He was commonly known as E. E. Barnard, and was recognized as a gifted observational astronomer. He is best known for his discovery of the high proper motion of Barnard's Star in 1916, which is named in his honor.

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 .
