About this world
BD-06 1339 c is a Neptune-like planet orbiting BD-06 1339, an orange dwarf (type K7/M0V) 66.1 light-years from Earth. It is about 0.75 times the size of Jupiter (its size estimated from its mass), with at least 0.17 Jupiter masses (a minimum, measured by radial velocity). It completes an orbit every 126 days at 0.43 AU from its star, on a strongly elongated orbit (e = 0.31).
Its equilibrium temperature is about 262 K (−11 °C), which places it in the conservative habitable zone: the band where liquid water could exist on a rocky surface. At its size it almost certainly keeps a deep envelope of hydrogen and helium.
It was discovered in 2013 by radial velocity with La Silla Observatory. The star wobbles toward and away from us, Doppler-shifting its spectrum. BD-06 1339 has 2 known planets; the others are BD-06 1339 b.
