HD 140283 is a star in the constellation Libra. It is one of the closest stars in Population II . With the help of the Hubble Space Telescope , the distance to it was determined to be 190 light years and its age - with an accuracy of ± 800 million years - estimated to be around 14.5 billion years. Due to the uncertainty of the value, its age does not contradict the age of the universe , which was determined by the Planck satellite to be 13.798 ± 0.037 billion years.
