HD 20367 b is an extrasolar planet approximately 88 light years away in the constellation of Aries. It has mass similar to that of Jupiter. It orbits the star at a mean distance that is a quarter farther than Earth orbits from the Sun. The 470-day (1.3 year) orbit is somewhat eccentric. This planet receives at average distance insolation similar to Earth, and at apastron and periastron insolation similar to that of Mars and Venus, so that if this planet has any moons, it may provide an environment suitable for supporting life.
