ESODid you find the <a href="https://astrodon.social/tags/StarWars" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#StarWars</a> world, Tatooine, and its companion stars impressive? Then check this! 😉ESO's Very Large Telescope (VLT) has discovered the first planet that not only orbits a pair of stars but does so at an angle of 90 degrees.Both stars are brown dwarfs, objects bigger than gas-giant planets but too small to be proper stars. When tracking their orbits, astronomers found that the orbits themselves change over time. After carefully ruling out other explanations, they concluded that the gravitational tug of a planet in a polar orbit was the only way to explain the motion of the brown dwarfs.Read more: <a href="https://www.eso.org/public/news/eso2508/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.eso.org/public/news/eso2508/</a>📷 ESO/L.
