 At the age of 2.8 billion years old, it has exhausted the hydrogen at its core, causing it to evolve away from the main sequence.As a consequence, it has expanded to 5.2 times the radius of the Sun although it only has 1.46 times the Sun's mass.The star is radiating 14.9 times the luminosity of the Sun from its swollen photosphere at an effective temperature of 4,994 K. One sub-stellar companion has been identified.
