“The Jerusalem Post is the oldest and largest English-language daily newspaper in Israel and the most-read English news website in Israel and the Jewish world.”
An internet search seems to indicate sheep farming is a big deal in Israel, so using sheep to give an indication of size might make more sense for a Jewish site?
> Asteroid 2023 HO18 is estimated by NASA to have a diameter of as much as 50 meters. In imperial measurements for American readers, that would be 164 feet or just under 55 yards.
Personally, I think for something as low stakes as an asteroid flying by the earth that having a bit of fun using a culturally relevant size estimation and associated puns is fine, especially considering they didn't just leave it at that and provided the more detailed information.
