It's called a kippah. "When praying" is the minimum.
Technically, it's to be worn during all waking hours; and that is what the Orthodox (and some others) do.
The kippah (also called yarmulkah) a reminder of the presence of God. This practice is twice mentioned emphatically in the Talmud (Shabbat 156b; Kallah 1:16), in statements dating back 1700 and 1850 years, respectively. Even then, covering one's head is spoken of as an established practice, not something new.
In Hebrew: kippa.
In Yiddish: yarmulkah.
Both of these words are often used in English.
