HD 33283 is an 8th magnitude star in the constellation Lepus. It is located 94 parsecs (310 light years) away from the solar system.[1] HD 33283 is similar to our Sun in terms of spectral type [G4V]. However, the star dwarfs the Sun by 24% more massive, 20% larger, 217 K hotter, and 232% more metals. The star is younger than our Sun by 40%.

In 2006, Johnson found a jovian planet orbiting HD 33283.
