HD 53143 is a star in the Carina constellation, located about 59.8 light-years (18.3 parsecs) from the Earth.

Using the technique of gyrochronology, which measures the age of a low-mass star based on its rotation, HD 53143 is about 1,010 ± 130 million years old.

The effective temperature of the star's outer envelope is cooler than the Sun at 5,224 K, giving it a golden-orange hue.

[7] Based upon an excess of infrared emission, a circumstellar debris disk has been found in this system.

[13] This disk is inclined at an angle of about 40–50° to the line of sight from the Earth and it has an estimated mass of more than 7 × 1020 kg.
