This is the oldest Known Exoplanet. It is over 12 billion years old. When our sun ignited some 5 billion years ago, this planet had already existed for more than 7 billion years. Is it any wonder it’s nicknamed the Methuselah planet? At a distance from Earth of more than 12,000 light-years, it is doubtful that human eyes will ever see its pulsar sun illuminating the nighttime cloud tops of this gas giant. Glistening in the softly lit sky, a myriad of stars from the globular cluster Messier 4 rise and set. Methuselah’s binary star system and its proximity to a globular cluster may result in a tragic fate for this elder of planets. The system’s slow drift toward the core of the cluster may result in a close encounter with a nearby star. The outcome: Methuselah will likely be ejected from the system, doomed to wander alone in interstellar space.
