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 = "Marspedia",
   title = "Planetary protection --- Marspedia{,} ",
   year = "2023",
   url = "\url{https://marspedia.org/index.php?title=Planetary_protection&oldid=140185}",
   note = "[Online; accessed 9-December-2025]"
 }
