It has a yellow hue and is too faint to be viewed with the naked eye, having an apparent visual magnitude of 8.70.
[2] The distance to this object is 266 light years based on parallax,[1] but it is drifting closer to the Sun with a radial velocity of −14 km/s.
[3] The star is roughly 6.3 billion years old and is spinning with a projected rotational velocity of 5.6 km/s.
HD 4203 is radiating 1.68 times the luminosity of the Sun from its photosphere at an effective temperature of 5,666 K.[4] Radial velocity observations of this star during 2000–2001 found a variability that suggesting an orbited sub-stellar companion, designated component 'b'.
[3] Additional observations led to a refined orbital period of 432 days with a relatively high eccentricity of 0.52 for a gas giant companion.
