HN has a policy of using the original title: https://news.ycombinator.com/newsguidelines.html

> In Submissions

[...]

> If the original title begins with a number or number + gratuitous adjective, we'd appreciate it if you'd crop it. E.g. translate "10 Ways To Do X" to "How To Do X," and "14 Amazing Ys" to "Ys." Exception: when the number is meaningful, e.g. "The 5 Platonic Solids."

> Otherwise please use the original title, unless it is misleading or linkbait.

In small obscure threads the mods sometimes don't notice and you can get away with small changes, like replacing "Photos of Encedalus" with "Photos of Encedalus, moon of Saturn". (But don't try "Amazing photos of Ecedalus will blow your mind!!!")

In big popular controversial thread almost always the title is reverted to the original title of the article, or the first sentence of the article when the tittle is too bad.
