HD 143436 is a star in the constellation Serpens. The temperature, rotation, mass, and abundance of elements in this star are indistinguishable from the same properties in the Sun, and for this reason it is a solar twin candidate. The only notable difference is an approximately six times higher abundance of lithium compared to the Sun. The space velocity components of this star are (U, V, W) = (−19.2, −38.6, −7.0) km/s.[4]
