摘要: Abstract Minor planet 1993SC, with a semi-major axis of 39.67 AU, is one the brightest numerous recently discovered objects orbits close to or beyond Neptune. It member Kuiper Belt, planetesimal population remaining from formation Solar System. We present optical photometry which indicates lightcurve amplitude less than 0.2 magnitude for 1993SC and does not support 0.5 I. P. Williams et al. ( Icarus 116, 180–185, 1995). derive (Kron-Cousins photometric system) V − R = 0.54 ± 0.14, I 0.97 J 2.08 0.15, confirm that has optical/infrared colors closer Centaur 1993HA 2 extremely red 5145 Pholus. also find VRI published by J. X. Luu D. C. Jewitt Astron. 111, 499–503, 1996) are inconsistent their reflectance spectrum we new values 0.56 0.08 1.19 0.18, give reasonable agreement our results.
