This is a list of high-proper motion stars. The 34 sources with the highest proper motion, based on data from the highly accurate Gaia catalogues, was...

orbital period of Jupiter. common proper motion A term used to indicate that two or more stars share the same motion through space, within the margin of...

Kevin Luhman in March 2013, who noticed the object's unusually high proper motion while searching for potential binary companions of the Sun in WISE images...

46 million km (0.31 AU; 29 million mi) from the Sun at perihelion. The proper motion of Sgr A* is approximately −2.70 mas per year for the right ascension...

photographic plates taken at different times during a proper motion survey. These showed large proper motion and parallax similar in both size and direction...

the proper motion velocity can be calculated. Together with the radial velocity, the total velocity can be calculated. Stars with high rates of proper motion...

white dwarfs.: 2  Eventually, many faint white stars that had high proper motion were found, indicating that they could be suspected to be low-luminosity...

61 Cygni first attracted the attention of astronomers when its large proper motion was first demonstrated by Giuseppe Piazzi in 1804. In 1838, Friedrich...

2017 revealed that the structure observed by Herschel shows no common proper motion with Zeta Reticuli. In these observations, no significant flux has been...

In physics, motion is when an object changes its position with respect to a reference point in a given time. Motion is mathematically described in terms...

Brownian motion is the random motion of particles suspended in a medium (a liquid or a gas). The traditional mathematical formulation of Brownian motion is...

velocity of a star is the component of its motion that is toward or away from the Sun. Unlike proper motion, a star's radial velocity cannot be directly...

to the Solar System, this real motion of a star is divided into radial motion and proper motion, with "proper motion" being the component across the...

Orion's stars will gradually move away from the constellation due to proper motion. However, Orion's brightest stars all lie at a large distance from the...

stellar motion was detected by these efforts. However, in 1918 the Dutch–American astronomer Adriaan van Maanen was able to measure the proper motion of stars...
