Vulcan's orbital period (year) was 203 days long of 24 hours, and was a harsh, desert planet (96%) with barely a quarter of its surface area
containing water. It possessed a thin atmosphere (20 kms) and high gravity (1.4 G).
. T'Khut (also known as Vulcan III, Vulcanis III, The Watcher, T'Rukh, T'Kuht, T'Khul, Valdena & Charis), with which it shared an orbit around a common center of gravity; the two worlds were a mere 249,895 kms apart, and T'Khut would fill the sky of the single hemisphere of Vulcan it was visible from due to the planets being tidally locked.
