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.
[1] [13] However, more recent models of its stellar evolution have suggested revision of the star's age to 13.7 billion years [14] or 12 billion years. [5] Dubbed the "Methuselah Star" by the popular press due to its age, [15] [16] the star must have formed soon after the Big Bang [1] and is one of the oldest stars known as of 2021. [5]
Hence this is the age estimate for the birth of the planet, and two stars. There is a minor dispute about the proper nomenclature rules to use for this unusual star system. One side regards the A/B convention of naming binary stars as having priority, so that the pulsar is PSR B1620−26 A, the white dwarf companion is PSR B1620−26 B and the ...
Some believe that Methuselah's extreme age is the result of an ancient mistranslation that converted "months" to "years", producing a more credible 969 lunar months, or 78½ years, [24] but the same calculation applied to Enoch would have him fathering Methuselah at the age of 5 [25] using numbers from the Masoretic Text.

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.
The claim that Methuselah is the oldest known tree is controversial. Methuselah was 4,789 years old when sampled in 1957 [13] by Edmund Schulman and Tom Harlan, [1] with an estimated germination date of 2833 BC. Dendrochronologist Matthew Salzer of the University of Arizona has been unable to reproduce Schulman's age estimate, due to a missing ...
3.0 billion years (10.8 billion Gya): Formation of the Gliese 581 planetary system: Gliese 581c, the first observed ocean planet and Gliese 581d, a super-Earth planet, possibly the first observed habitable planets, form. Gliese 581d has more potential for forming life since it is the first exoplanet of terrestrial mass proposed that orbits ...
Bristlecone pines are known for attaining great ages. The oldest bristlecone pine in the White Mountains is Methuselah, which has a verified age of 4,856 years. It is located in the White Mountains of Inyo County in Eastern California. However, the specific location of Methuselah is a closely guarded secret. [15]
