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.
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 planet is PSR B1620−26 c. The other side considers PSR to apply only to ...

The exoplanet PSR B1620-26 b forms. It is a gas giant, the oldest observed exoplanet in the Universe, orbiting a pulsar and a white dwarf. Visual limit of Hubble Deep Field. Since (known) universe still small in size, galaxy interactions become common as larger and larger galaxies form out of galaxy merger process.
