HD 49674 b is an extrasolar planet located approximately 134 light-years away in the constellation of Auriga, orbiting the star HD 49674. This planet was discovered orbiting the star in 2002. At the time of discovery, it was the least massive extrasolar planet known, being less than half the mass of Saturn, but smaller planets were discovered in 2004. The planet is a gas giant and orbits extremely close to its star, which takes only 4.95 days to revolve. Surface temperatures would be very high, and the planet probably has a faint red glow.
