HD 154672 b is an extrasolar planet located approximately 210 light-years away[2] in the constellation of Ara, orbiting the metal-rich and aged star HD 154672. This planet has a minimum mass five times that of Jupiter and orbits at about 60% the distance between the Earth to the Sun. Its orbit is very elliptical, which causes temperatures on the planet to vary significantly as it proceeds along its orbit. This planet was discovered in Las Campanas Observatory on September 5, 2008 using the radial velocity method (Doppler spectroscopy). Along with HD 205739 b, the planets were the first to be discovered by the N2K Consortium using the Magellan Telescopes.
EPE was invoked but never defined (see the help page).
