The Talmud (RH 24b; brought also in Sh.Ar. YD 141, 7) says it is forbidden to make a shape of sun, moon or stars.
לא תעשון כדמות שמשיי המשמשין לפני כגון חמה לבנה כוכבים ומזלות
So, is it permitted to type an asterisk?

It is only forbidden to make the form of a celestial body if it was intended as such. So an asterisk or a plain circle or a zero or the letter O or a picture of a starfish is permitted.
