70 Ophiuchi planet. Computer artwork of a hypothetical gas giant planet orbiting one of the stars in the 70 Ophiuchi binary star system, seen from its moon. The 70 Ophiuchi system comprises two orange dwarf stars (upper left and lower right) in a mutual orbit. The Jupiter-like planet seen here has flashes of lightning (white) and aurorae (pink, around the poles) seen on its night side. The 70 Ophiuchi system lies less than 17 light years from Earth in the constellation Ophiuchus.
