HD 142415 is a 7th magnitude yellow main-sequence star 113 light years from Earth in the southern constellation Norma. This star dwarfs the Sun in terms of mass (1.09x), size (1.03x), luminosity (1.1x), temperature (1.01x), and metallicity (1.62x). The age of the star is as young as 1.5 billion years.

The star currently has one planet.

discovery_status=Published HD 142415 b is an exoplanet with the semi-amplitude of 51.3±2.3 m/s. This indicates the minimum mass of 1.69 Jupiter mass, an orbital period of 386.3 days, and the semi-major axis of 1.07 astronomical units based from its stellar mass. The wild, oval pathed wobble of the star used by Doppler spectrometer indicates that the orbit of the planet is highly eccentric at around 50%.

The planet was discovered in California of the United States in 2003 by Mayor, who discovered 51 Pegasi b orbiting around 51 Pegasi back in 1995.
