Historical Note on Neptune

Neptune was predicted independently by John Couch Adams and Urbain Le Verrier by a process of mathematical investigation of discrepancies in the orbit of Uranus between $1843$ and $1846$.

It was first observed and recognised for what it was by Johann Gottfried Galle on $23$rd September $1846$, within a degree of where it was predicted to be.
