(5726) Ruby is an asteroid of the main inner belt discovered on January 24, 1988 by the American astronomer Carolyn Shoemaker at the Palomar Observatory ( IAU code 675) in California .
The asteroid belongs to the Phocaea family, a group of asteroids named after (25) Phocaea . The 4: 1 orbital resonance with the planet Jupiter is characteristic of this group . The solar orbit of (5726) Rubin is strongly inclined at more than 25 ° compared to the ecliptic of the solar system , which is characteristic of Phocaea asteroids.
(5726) Rubin was named on April 22, 1997 after the American astronomer Vera Rubin (1928-2016), who mainly dealt with the determination of the distribution of dark matter .
