S Ori 70 es un planeta extrasolar ubicado en el cúmulo de Sigma Orionis en la constelación de Orión. Tiene una masa que supone tres masas jovianas y es un planeta gaseoso. Fue descubierto el 24 de noviembre de 2002 por la señora Zapatero Osorio y un equipo del Observatorio del Roque de los Muchachos. Aún no se ha determinado si se trata de una enana marrón o un planeta de 3 millones de años de edad, que forma parte de un clúster.[1][2]

Es posiblemente una subenana marrón.

S Ori 70 or S Ori J053810.1-023626 is a mid-T type astronomical object in the foreground of the σ Orionis cluster, which is approximately 1,150 light-years from Earth. It was discovered on November 24, 2002 by M. R. Zapatero-Osorio and E. L. Martin's team at the Roque de los Muchachos Observatory. It has yet to be determined if it is a field brown dwarf or a 3-million-year-old planet that is part of a cluster. Near-infrared spectroscopy images taken 3 years after its discovery led to the first motion measurements for the object. Its behavior is significantly different from what may be expected; it was further described as either a low-gravity atmosphere or an atmosphere with metallicity. The object's small proper motion suggests that it is farther away than expected if it were a single field T dwarf.
