Asteroid
5653 Camarillo (
KAM -ə-REE -oh ), provisional designation 1992 WD5 , is a stony
asteroid and
near-Earth object of the
Amor group , approximately 1.5 kilometers in diameter.
It was discovered on 21 November 1992, by American astronomers
Eleanor Helin and
Kenneth Lawrence at
Palomar Observatory in California, United States.
[2] The asteroid was named for the Californian town of
Camarillo .
[13]
Orbit and classification
Camarillo orbits the Sun at a distance of 1.2–2.3
AU once every 2 years and 5 months (878 days). Its orbit has an
eccentricity of 0.30 and an
inclination of 7
° with respect to the
ecliptic .
[1]
It has an Earth minimum orbit intersection distance ,
MOID , of 0.2846 AU (42,600,000 km), which corresponds to 110.9
lunar distances .
[1]
A first
precovery was taken at the Australian
Siding Spring Observatory in 1974, extending the body's
observation arc by 18 years prior to its official discovery observation at Palomar.
[2]
Physical characteristics
The
S-type asteroid has also been characterized as a Sr-subtype, a transitional group to the
R-type asteroids .
[11]
Lightcurves
Between 1995 and 2015, several rotational
lightcurves of Camarillo gave a well-defined
rotation period of 4.834 hours with a brightness amplitude between 0.4 and 0.85
magnitude .

Diameter and albedo
According to the surveys carried out by NASA's space-based
Wide-field Infrared Survey Explorer with its subsequent
NEOWISE mission, Camarillo has an
albedo between 0.21 and 0.25 with a corresponding diameter of 1.53 to 1.57 kilometers.

Naming
This
minor planet was named after for the Californian town of
Camarillo and its Camarillo Observatory (
670 ). The town was named after Adolfo Camarillo (1864–1958), a well known regional rancher. The first discoverer is a former town resident.
[13] The official naming citation was published by the
Minor Planet Center on 4 August 2001 (
M.P.C. 43189 ).
