HD 140283 (also known as the Methuselah star) is a metal-poor subgiant star about 200 light years away from the Earth in the constellation Libra, near the boundary with Ophiuchus in the Milky Way Galaxy. Its apparent magnitude is 7.205, so it can be seen with binoculars. It is one of the oldest stars known.
PSR B1620-26 b is an exoplanet located approximately 12,400 light-years from Earth in the constellation of Scorpius.It bears the unofficial nicknames "Methuselah" and "the Genesis planet" (named after the Biblical character Methuselah, who, according to the Bible, lived to be the oldest person) due to its extreme age.
The subgiant star HD 140283, believed to be the oldest extant star discovered, is often nicknamed "The Methuselah Star" after the ancient biblical figure. [45] The name is also used to refer to the exoplanet PSR B1620−26 b, which is one of the oldest known exoplanets with an estimated age of 12.7 billion years old. [46]
PSR B1620−26 is a binary star system located at a distance of 3,800 parsecs (12,400 light-years) in the globular cluster of Messier 4 (M4, NGC 6121) in the constellation of Scorpius. [ 2 ] [ 3 ] [ 4 ] The system is composed of a pulsar ( PSR B1620−26 A ) and a white dwarf star (WD B1620−26, or PSR B1620−26 B ).
The age of the oldest known stars approaches the age of the universe, about 13.8 billion years. Some of these are among the first stars from reionization (the stellar dawn), ending the Dark Ages about 370,000 years after the Big Bang. [1] This list includes stars older than 12 billion years, or about 87% of the age of the universe.

A star is a massive luminous spheroid astronomical object made of plasma that is held together by its own gravity.Stars exhibit great diversity in their properties (such as mass, volume, velocity, stage in stellar evolution, and distance from Earth) and some of the outliers are so disproportionate in comparison with the general population that they are considered extreme.
