The List of unnumbered trans-Neptunian objects (TNOs) refers to a category of celestial objects in the outer solar system, beyond the orbit of Neptune, that have been observed but not officially assigned a number by the Minor Planet Center. In 2011, numerous observations of such objects were made, and while many were noted, they remained unnumbered due to various reasons such as incomplete data or the need for further observation to confirm their orbits.
