Meet Ammonite, the oldest iceberg in the Solar System.
Officially 2023 KQ₁₄. In fact, it is an icy hermit wandering far beyond Neptune. Its perihelion is 66 AU, and its orbit is so elongated that one revolution around the Sun takes about 4,000 years.
It is not a planet, but a sednoid, one of only four objects known to us with such characteristics.
Discovered by Japanese astronomers using the Subaru telescope in Hawaii.
