HD 122430 is an orange giant star about 440 light years away in the constellation of Hydra on the celestial sphere. The star has completely run out of the hydrogen fuel, which keeps the star stable, although its age is only 3.1 billion years old, younger than the Sun’s 4.6 billion years. HD 122430 has a mass of 1.4 times and radius of 22.9 times that of the sun. Despite its younger age, it has slightly lower metallicity, approximately 90%.

  • HD 122430 is an orange giant star about 440 light years away in the constellation of Hydra on the celestial sphere. The star has completely run out of the hydrogen fuel, which keeps the star stable, although its age is only 3.1 billion years old, younger than the Sun’s 4.6 billion years. HD 122430 has a mass of 1.4 times and radius of 22.9 times that of the sun. Despite its younger age, it has slightly lower metallicity, approximately 90%. The temperature of its surface is approximately 4300 kelvins.
  • HD 122430 ist ein 440,37 Lichtjahre von der Erde entfernter oranger Riese mit einer Rektaszension von 14h 02m 22s und einer Deklination von -27° 25' 47" .
