Abstract
Precision Doppler velocity measurements from the 3.9 m Anglo-Australian Telescope reveal a planet with a 6 yr period orbiting the G5 dwarf HD 70642. The a = 3.3 AU orbit has a low eccentricity (e = 0.1), and the minimum (M sin i) mass of the planet is 2.0MJUP. The host star is metal-rich relative to the Sun, similar to most stars with known planets. The distant and approximately circular orbit of this planet makes it a member of the rarest group to emerge from precision Doppler surveys.
