Poyasnenie: Valuny, besporyadochno razbrosannye po nerovnoi poverhnosti asteroida 433 Eros, yarko sverkayut v luchah zahodyashego Solnca. Samyi yarkii valun na krayu bol'shogo temnogo kratera v seredine nizhnego kraya fotografii, imeet poperechnik okolo 30 metrov. Eta fotografiya byla poluchena ranee v etom mesyace s vysoty primerno 50 kilometrov kameroi avtomaticheskoi mezhplanetnoi stancii NEAR Shoemaker, s fevralya 2000 goda nahodyasheisya na orbite vokrug Erosa. Sam Eros obrashaetsya vokrug Solnca po orbite s perigeliem 1,13 astronomicheskoi edinicy (a.e.) i afeliem 1,78 a.e. On vhodit v gruppu asteroidov, sblizhayushihsya s Zemlei, i bol'shuyu chast' vremeni provodit mezhdu orbitami Marsa (radius 1,5 a.e.) i Zemli (1 a.e.). Odnako on ne vsegda byl na takoi orbite. Eros i drugie sblizhayushiesya s Zemlei asteroidy, pervonachal'no nahodilis' v osnovnom poyase asteroidov, mezhdu Yupiterom i Marsom.
