Radial velocity is the velocity of an object in the direction of the line of sight. ... The proper motion of a star is the motion of the position of the star in the sky (the change in direction in which we see it, as opposed to the radial velocity) after eliminating the improper motions of the stars, which affect their measured coordinates but are not real...

Lacaille 9352 (493 words)
Lacaille 9352 is located about 10.7 light-years (ly) from our Sun, Sol, in the southwestern edge (23:05:42.04-35:51:11.06, ICRS 2000.0) of Constellation Piscis Australis (or Austrinus), the Southern Fish, near Constellation Grus, the Crane -- southeast of Beta Piscis Australis/Austrini and southwest of Gamma and Delta Piscis Australis/Austrini.
Lacaille 9352 (Gl or GJ 887) is larger
Lacaille 9352 may have less than half (47 percent) of Sol's mass, about half (47 to 57 percent) of its diameter, 1.1 percent of its luminosity, and only about one tenth of Sol's abundance of elements heavier than hydrogen ("metallicity").
Lacaille 8760 / AX Mic (630 words)
Also known as AX Microscopii, Lacaille 8760 is located about 12.9 light-years (ly) from our Sun, Sol, in the south central part (21:17:15.3-38:52:2.5, ICRS 2000.0) of Constellation Microscopium, the Microscope -- south of Alpha Microscopii, southwest of Gamma Microscopii, northwest of Theta1 Microscopii, and north of Zeta and Alpha Indi (The Persian).
Although Lacaille 8760 is the brightest red (more orange-red to some astronomers) dwarf star in Earth's night sky, the star is too faint to be seen with the naked eye by most Humans (Kenneth Croswell, 2002).
Lacaille 8760 may have around 60 percent of Sol's mass (RECONS), about 66 to 72 percent of its diameter ((Pasinetti-Fracassini et al, 2001; Johnson and Wright, 1983, page 699; and Claude H.
