It has visual magnitude 4.43 meaning that you could see this star with the naked eye in good viewing conditions. It is marked in the center of this star chart, at celestial coordinates (J2000 equinox):

This star is 16.4 light years away, which means that the light we see from it today set off on its journey at about the same time that you were born. Come back in a month or two and your birthday star may change, as the light from more distant stars reaches Earth.

triple = 3 (oh baby)
pwnon = illuminati, waterore = comrade
