BD+05 4868 A is a K V star, a cooler dwarf than the Sun, lying 142 light-years away. Its reported mass is 0.7 solar masses and its reported radius is 0.69 solar radii, both smaller than the Sun's, while its reported temperature of 4600 K is cooler than the Sun's. The star's age is given as 11.1 billion years. One planet is known to orbit it.
That planet, BD+05 4868 A b, was found by transit in 2025. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. Its orbital period is 1.27 days. Its mass carries a reported upper limit of 6.2 Earth masses, a bound rather than an exact value.
