(7348) 1993 FJ22 asteroid from the outer region of the asteroid belt , about 10 kilometers in diameter. It was discovered on 21 March 1993, by the Uppsala-ESO Survey of Asteroids and Comets (UESAC) at ESO 's La Silla Observatory site in northern Chile.[5]
Classification and orbit [ edit ]
The dark C-type asteroid is a member of the Themis family , a dynamical family of outer-belt asteroids with nearly coplanar ecliptical orbits .[2] outer main-belt at a distance of 2.8–3.4 AU eccentricity of 0.11 and an inclination of 1° with respect to the ecliptic . It was first identified as 1933 FU at Heidelberg in 1933, extending the body's observation arc by 60 years prior to its official discovery observation at La Silla.[1]
Physical characteristics [ edit ]
Lightcurves [ edit ]
In 2014, two rotational lightcurves of this asteroid were obtained from photometric observations in the R-band at the U.S. Palomar Transient Factory in California. Lightcurve analysis gave a rotation period of 3.4735 and 3.470 hours with a brightness variation of 0.10 and 0.13 in magnitude , respectively (U=2/2 [3] [4]
Diameter and albedo [ edit ]
The Collaborative Asteroid Lightcurve Link (CALL) assumes a low albedo of 0.08 for the asteroid's surface and calculates a diameter of 9.9 kilometers, based on an absolute magnitude of 13.38.[2]
As of 2017, the asteroid has not been named.[5]
