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 = "Hellas Planitia --- Marspedia{,} ",
   year = "2018",
   url = "\url{https://marspedia.org/index.php?title=Hellas_Planitia&oldid=125219}",
   note = "[Online; accessed 21-March-2026]"
 }
