Lakshmi Planum is a plateau feature approximately 2 million km2 ringed by rugged mountains,[1][2] the surface of Venus on the Western Ishtar Terra.[3] It is named after Lakshmi, the Hindu goddess of wealth.

It is roughly 3.5 to 5 kilometers (2.2 to 3.1 mi) above the mean planetary radius, featuring two large oval depressions (Colette and Sacajawea).[2]

The plains of Lakshmi are made up of radar-dark, homogeneous, smooth lava flows.[4]

Lakshmi Planum is ringed by intensely deformed terrain,[5] some of which is shown in the southern portion of the image and is called Clotho Tessera.[6]

  • Lineated plains in Lakshmi Region.Two sets of parallel lineations are seen intersecting almost at right angles
  • The radar smooth region in the northern part of the image is Lakshmi Planum, ringed by the intensely deformed terrain of Clotho Tessera.
  • Sacajawea Patera, a large, elongate caldera on the smooth plateau of Lakshmi Planum, approximately 1.2 km deep and 120 by 215 km in diameter.
