HD 33283 b is an exoplanet orbiting around HD 33283. The mass of the planet is about 1/3 that of Jupiter or about the same as Saturn. However, the planet orbits very close to the star, taking only 18 days to complete its orbit with average speed of 86.5 km/s. Despite of this, its orbit is chaotic, bringing as close as 0.075 AU to as far away as 0.215 AU.
