When using the LaTeX package url (\usepackage{url} somewhere in the preamble) which tends to give much more nicely formatted web addresses, the following may be preferred:

 @misc{ wiki:xxx,
   author = "U-Sphere - Michael Vaillant",
   title = "Comètes et Planète X --- U-Sphere - Michael Vaillant{,} ",
   year = "2009",
   url = "\url{http://www.u-sphere.com/wiki//index.php?title=Com%C3%A8tes_et_Plan%C3%A8te_X&oldid=21505}",
   note = "[Online; accessed 26-octobre-2025]"
 }
