It has the traditional star name Oculus (meaning eye in Latin); Pi Capricorni is its Bayer designation, which is Latinized from π Capricorni and abbreviated Pi Cap or π Cap. This system appears blue-white in hue and is visible to the naked eye as a 5th magnitude star. It is located approximately 660 light years distant from the Sun based on parallax, but is drifting closer with a radial velocity of −13 km/s. The proximity of this star to the ecliptic means it is subject to lunar occultation.
