NASA and China are considering a mission to one of the most distant planets in our solar system, the seventh, one of the last. Long ignored, we only visited it once, with the quick flyby of Voyager 2 in 1986. This icy giant, with surprising features, remains little known. What are the main scientific questions posed by undertaking such a journey?

today’s report

The orbits and axes of rotation of the planets in the Solar System are not due to chance. They keep as “memory” the conditions of their formation and their evolution. Trying to understand why Uranus has an obliquity of 98°, unlike the other giant planets, improves our understanding of how the solar system formed. meeting with Melaine Sailenfest Y gwenael boue of the Institute of Celestial Mechanics and Ephemeris Calculation (IMCCE) of the Paris Observatory, on the subject of your article to be published in astronomy and astrophysics.
