Its latitude is 77° 29' N and its longitude 82° 30' E. It is often labelled as Einsamkeit Island (from the German "Insel der Einsamkeit") as well as Lonely Island or Solitude Island in English maps. The island is barren and icy throughout the winter months, but some tundra vegetation grows on it in the summer. Its length is and its total area is . Compared to other Arctic islands it is
Baltica belt of the Timanide orogeny and overlain by Mesoproterozoic sediments. The margin became a passive margin facing an Ural Ocean in the Cambrian-Ordovician. The eastern margin stretches south through the Ural Mountains from the northern end of the Novaya Zemlya archipelago. The margin follows the bent shape of Novaya Zemlya which was caused in the Late Permian by the Siberian Traps. It is clear from Baltic endemic fossils in Novaya Zemlya that the islands have been part of Baltica since Early Palaeozoic, whereas the Taymyr Peninsula farther east was part of the passive margin of Siberia in the Early Palaeozoic.
