• •A Tatooine-like planet, 2M1510(AB)b, has been discovered orbiting two brown dwarfs in a polar orbit, a first for circumbinary systems.
• •Unlike Tatooine, which orbits two suns, 2M1510(AB)b orbits two brown dwarfs, which are 'failed stars'.
• •The polar orbit of 2M1510(AB)b is more stable than co-planar orbits and could lead to unique seasonal variations due to the changing distances of the brown dwarfs.
• •The discovery, published in Science Advances, offers insights into planetary formation and the diverse possibilities of circumbinary systems.

Astronomers have discovered a unique exoplanet, 2M1510(AB)b, which orbits two brown dwarfs in a polar, or up-and-down, fashion. This 'Tatooine-like' world presents a significant departure from previously discovered circumbinary planets that orbit in a co-planar fashion. The polar orbit could lead to unusual seasonal changes due to the varying distances from the brown dwarfs. This discovery, published in Science Advances, expands our understanding of planetary formation and the potential for life in binary star systems.
