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 = "Wikipedia",
   title = "NGC 4551 --- Wikipedia{,} Entziklopedia askea",
   year = "2023",
   url = "\url{https://eu.wikipedia.org/w/index.php?title=NGC_4551&oldid=9501575}",
   note = "[Online; accessed 20-uztaila-2024]"
