The Universe's oldest planet (so far)

Hey has there been any discussion about this object here before? It's
about a planet orbiting a pulsar and a white dwarf inside a globular
cluster. I know the story is a little old, but I found it fascinating. A
planet that's 12.7 billion years old! Just a billion years after the
Universe was banged out. The planet is in the pulsar system PSR B1620-26
in the globular cluster M4.

The fact that the whole solar system was captured by the pulsar which
already had a white dwarf around it, that it flung off to capture this
solar system. The solar system was so old it's not even clear if there
could've been rocky planets around it at one time, or if rocks hadn't
yet formed.

Ancient Life
"Astronomers have discovered the oldest known planet, a primeval world
12.7 billion years old that will force them to reconsider how and when
planets form. The discovery raises the prospect that life may have begun
far sooner than most scientists ever imagined."
