Astronomers have discovered a mysterious object orbiting far beyond Pluto that could be a new dwarf planet, taking approximately 280 years to complete one orbit around the Sun. The find adds to the growing list of distant solar system bodies detected in recent years.
Background
New Trans-Neptunian Objects (TNOs) have been increasingly discovered since the late 1990s thanks to improved survey telescopes like the Palomar Transient Factory and Dark Energy Camera. The Kuiper Belt and scattered disk region remain among the least explored frontiers of our solar system.
