Abstract
We studied 12 asteroids, (3285) Ruth Wolfe, (1035) Amata, (505) Cava, (1320) Impala, (1148) Rarahu, (176) Iduna, (1494) Savo, (2709) Sagan, (164) Eva, (4606) Saheki, (122) Gerda, and (48) Doris. The data selected from the ALCDEF database based on the short period asteroids. We calculate the orbital rotation speed, and rotation period, and also analysis of 33 light curves with Period4 software. Therefore, we show the place of each asteroid on the frequency-diameter diagram, and all asteroids are below the limit line.
