Scientists are racing to send a spacecraft to Sedna, a distant dwarf planet on an elongated orbit that will be closest to the Sun in 2076, to study its composition and origins before it moves away again. Due to the extreme distance, innovative propulsion methods like solar sails or fusion drives are being considered, but both face significant technical challenges. A successful mission could provide valuable insights into the early Solar System and potentially extraterrestrial material, but timing and technological development are critical.
A feasibility study explores the possibility of sending a mission to Sedna, a distant trans-Neptunian object, using advanced propulsion technologies like nuclear propulsion and solar sails, with potential mission durations ranging from about seven to ten years, aiming to study its surface and gain insights into the early Solar System.
Scientists are developing nuclear fusion and solar sail propulsion methods to reach the distant dwarf planet Sedna in just seven years, aiming to explore the outer solar system and gain insights into its formation, despite engineering challenges.

The James Webb Space Telescope (JWST) has observed three dwarf planets in the Kuiper Belt - Sedna, Gonggong, and Quaoar - using its Near-Infrared Spectrometer (NIRSpec). The observations revealed interesting information about their orbits and composition, including the presence of light hydrocarbons and complex organic molecules believed to be the result of methane irradiation. These findings provide insights into the history and evolution of objects in the outer solar system and highlight the capabilities of the JWST in studying our cosmic neighborhood.
