106 Aquarii (abbreviated 106 Aqr) is a star in the equatorial constellation of Aquarius. 106 Aquarii is the Flamsteed designation although it also bears the Bayer designation i1 Aquarii. It has an apparent visual magnitude of +5.2, making it bright enough to be viewed from the suburbs according to the Bortle Dark-Sky Scale. An annual parallax shift of 8.61 milliarcseconds yields an estimated distance of around 380 light-years (120 parsecs) from Earth.
The spectrum of this star fits a stellar classification of B9 V, indicating this is a B-type main sequence star. It is spinning rapidly with a projected rotational velocity of 370 km/s. X-ray emission with a luminosity of 6.0 × 1029 erg s−1 has been detected from this star. This is unusual since a B-type star normally does not have any significant X-ray emission. Instead, it may have an undetected lower mass companion.
