164589 La Sagra
164589 La Sagra is an asteroid of the Euterpe family from the inner regions of the asteroid belt. It is approximately in diameter. It was discovered on 11 August 2007, by astronomers of the Astronomical Observatory of Mallorca at its robotic La Sagra Observatory in Grenada, Spain. It was named after Mount La Sagra and the discovering La Sagra Observatory.
La Sagra is a member of the Euterpe family, a small family of stony asteroids named after its principal body, 27 Euterpe. It orbits the Sun in the inner asteroid belt at a distance of 1.9–3.0 AU, completing an orbit once every 3 years and 10 months. Its orbit has an eccentricity of 0.22 and an inclination of 1° with respect to the ecliptic. Its observation arc begins with a precovery taken by Spacewatch in October 1992, nearly 15 years prior to its official discovery observation at La Sagra Observatory.
Naming
This minor planet takes its name from the mountain La Sagra, the highest mountain of the Prebetic mountain range, on whose north hillside the La Sagra Observatory is located. It was the observatory's first numbered discovery. The official was published by the Minor Planet Center on 21 March 2008.
Physical characteristics
Since Euterpe asteroids are of silicaceous rather than carbonaceous composition, with a relatively high albedo around 0.26 , La Sagra measures approximately 1.2 kilometer in diameter, based on an absolute magnitude of 16.6. As of 2018, no rotational lightcurve of La Sagra has been obtained from photometric observations. The body's rotation period, pole and shape remain unknown.
