An international team of astrophysicists has presented a new concept explaining the significant tilt of Neptune's rotation axis. The researchers believe that the key factor in this process was the capture of Triton, the planet's largest moon, which entered the system early in its existence. Triton is unique in its retrograde motion: it orbits Neptune in the opposite direction to the giant's rotation. This fact has long been... The post "Triton's…
Neptune's Obliquity Was Likely Engendered By Triton's Tidal Evolution - Astrobiology
Neptune’s present axial tilt of approximately 28 deg. with respect to its orbital plane can be explained by collisions that its primordial core may have experienced with surrounding planetary embryos during the final stages of its formation. Alternatively, Neptune could have attained its present mass solely through pebble accretion, without the formation of nearby planetary […] The post Neptune’s Obliquity Was Likely Engendered By Triton’s Tidal…
