Neptunian planets are being explored in various studies, with some research focusing on the planet Neptune itself, including its moons, magnetic field, and rings. Additionally, there are investigations into objects beyond Neptune, including the potential discovery of a new, as yet undiscovered planet and the identification of rare distant objects and minor planets in the region. The term "Neptunian" may also refer to a type of exoplanet or a region of space, sometimes called the "Neptunian desert" or associated with a "Neptunian ridge" where exoplanets may be hiding.
