[1] This planet was discovered using the Doppler spectroscopy (radial velocity) method.

HD 4313 was discovered by a group of scientist at the Keck Observatory on March 17, 2010 using the Doppler spectroscopy method, which is detecting a planet by the star's change in wobbling.

[3] Its orbit distance is similar, about 1 AU away from its host star.

[3] According to the latest data, this planet has a somewhat eccentric orbit.

[3] HD 4313 has a mass only 92.7% greater than that of Jupiter, but its radius and inclination is unknown, so the true mass and radius can't be studied.
