Lambda2 Tucanae is a solitary[7] star in the southern constellation of Tucana. It is faintly visible to the naked eye with an apparent visual magnitude of +5.45.[2] Based upon an annual parallax shift of 14.6 mas as seen from Earth, it is located around 223 light years from the Sun. At that distance, the visual magnitude of the star is diminished by an extinction factor of 0.09 due to interstellar dust.[2]

This is an orange-hued K-type giant star on the red giant branch,[2] with a stellar classification of K2 III.[3] It has an estimated 1.75[2] times the mass of the Sun but after evolving away from the main sequence it has expanded to 9.8 times the Sun's radius. The star is radiating 39 times the solar luminosity from its photosphere at an effective temperature of 4,605 K.[1]
