[2] Janequeo is a member of the Flora family, one of the largest collisional populations of stony asteroids.
[8] In August 2010, a rotational lightcurve of Janequeo was obtained from photometric observations by astronomers at the Palomar Transient Factory in California.
Lightcurve analysis gave a short rotation period of 2.480 hours with a brightness amplitude of 0.27 magnitude (U=2).
[3] This minor planet was named after Janequeo (Yanequén), a heroine and leader of the native Mapuche people of Chile.
After her husband Huepotaén died in battle against the colonial Spaniards during the Arauco War in the 16th century, she became tribal chief and brought together various rebellious tribes.
