Medhavi is an impact crater in the southern hemisphere of the planet Venus . It is located in the Scarpellini Quadrangle , which is part of the Lavinia Planitia . The crater is located west of the Juksakka Corona and south of the Munter crater .
description
Medhavi has an average diameter of 30.4 kilometers. In the southern crater wall is the crater Michelle . There are no furrows on the crater floor, but the crater rests on the furrows in the surrounding landscape. Around the crater there is a distinct dark halo in a non-parabolic shape. Most of the craters on Venus are surrounded by bright ejecta . With Medhavi these can be clearly seen lying on the halo. To the west, the ejecta extends into the lowlands.
designation
The crater was named after the Indian social reformer and activist Ramabai Dongre Medhavi (1858-1922). Craters with a diameter of more than 20 kilometers on Venus are named after women who died and who achieved extraordinary things in their area. There are two other Venus craters named after Indian women. The names were all in 1994. Joshee was named after the doctor Anandi Gopal Joshi (1865-1887) and Jhirad after the doctor Jerusha Jhirad (1891-1984).
