S Ori 70, also known as S Ori J053810.1-023626, is a mid-T type astronomical object located approximately 1,150 light-years from Earth, discovered on November 24, 2002, by M. R. Zapatero-Osorio and E. L. Martin's team at the Roque de los Muchachos Observatory in La Palma. There is ongoing debate about whether it is a field brown dwarf or a 3-million-year-old planet belonging to the σ Orionis cluster. Its unusual behavior, possibly due to a low-gravity atmosphere or high metallicity, has fueled this controversy. Additionally, it could be one of the first "free-floating" or rogue planets discovered. The debate about its true nature remains open.
