Title: SMSS J031300.36-670839.3
Passage: SMSS J031300.36-670839.3 (shortened as SMSS J0313-6708; informally abbreviated to SM0313) is a star in the Milky Way at a distance of 6,000 light years from Earth.  With an age of approximately 13.6 billion years, it is one of the oldest stars known.  Another star, HD 140283, is considered to be older, but there is uncertainty in values of its age.  This makes SM0313 the oldest known star with an accurate determination of its age.  The star formed only about 100 million years after the Big Bang, and has been shining for 13.6 billion years.  The star's very low upper limit of iron of less than one ten millionth the iron level of the Sun, suggests that it is one of the first Population II stars, formed from a gas cloud enriched by some of the very first (Population III) stars.  SMSS J031300.36-670839.3 also has a much higher carbon supply compared to iron, more than a thousand times greater.  Apart from hydrogen, which appeared in the Big Bang, the star also contains carbon, magnesium, and calcium which could have been formed in a low energy supernova.  Methylidyne (CH) is also detected by its absorption line.  No oxygen or nitrogen have been detected.  The star is a K class dwarf.
