Arete (minor planet designation: 197 Arete) is an asteroid in the asteroid belt. It has a very bright surface, even so when compared to other rocky S-type asteroid.

It was discovered by J. Palisa on May 21, 1879, and named after Arete, the mother of NausicaainHomer's The Odyssey.[9] Every 18 years, this asteroid approaches within 0.04 AU of 4 Vesta. During these encounters, Vesta causes a gravitational perturbation of Arete, allowing the mass of Vesta to be directly determined.[10]

Photometric observations during 1984 showed a rotation period of 6.54 ± 0.02 hours and a brightness variation of 0.10 ± 0.01 in magnitude. The light curve shows "four well defined extrema with two asymmetric maxima".[11]
