NGTS-4b
Sign in to saveNGTS-4b is a Neptune-like planet orbiting the early K-type star NGTS-4, nicknamed the "forbidden planet" for its existence within the Neptunian desert, a location where very few Neptunian planets are found orbiting their stars. It was the first exoplanet discovered in the Neptunian desert.

NGTS-4b is a Neptune-like planet orbiting the early K-type star NGTS-4, nicknamed the "forbidden planet" for its existence within the Neptunian desert, a location where very few Neptunian planets are found orbiting their stars. It was the first exoplanet discovered in the Neptunian desert.
== Characteristics == NGTS-4b has a mass of 20 , and a radius 20% smaller than Neptune and has retained an atmosphere while orbiting every 1.3 days within the Neptunian desert of its star. The atmosphere may have survived due to the planet's unusually high core mass, or "it might have migrated to its current close-in orbit after this epoch of maximum stellar activity".
