Brown]] ([[California Institute of Technology\|Caltech]]), [[Chad Trujillo]] ([[observatorium Gemini]]) dan [[David Rabinowitz]] ([[Universitas Yale]]) pada [[14 November]] [[2003]]. Pada waktu ditemukan, Sedna merupakan benda langit dalam [[Tata Surya]] terjauh yang pernah diamati pada saat itu. Diameter Sedna sekitar 1.180 sampai 1.800 km dengan massa 1,7 - 6,1 x 10<sup>21</sup> kg. [[Perihelion]] Sedna 76,156 [[satuan astronomi\|AU]] sedangkan [[aphelion]]-nya 975,056 AU. Sedna membutuhkan 12.000 tahun untuk satu kali mengorbit [[Matahari]]. Baris 82: [[Kategori:Objek trans-Neptunus]] {{astronomi-stub}}
