ι Microscopii, Latinized as Iota Microscopii, is a suspected astrometric binary[10] star system in the southern constellation of Microscopium, near the southern constellation border with Indus.

It is visible to the naked eye as a dim, yellow-white hued point of light with an apparent visual magnitude of 5.11.

[2] This object is 121 light years from the Sun based on parallax, but is drifting closer with a radial velocity of −14 km/s.

[1] The visible component is an ordinary F-type main-sequence star with a stellar classification of F2V,[3] which indicates it is generating energy through core hydrogen fusion.

The star is radiating 13[2] times the luminosity of the Sun from its photosphere at an effective temperature of 6,997 K.[6] It has a high rate of spin with a projected rotational velocity of 115 km/s, which is giving the star an equatorial bulge that is 6% larger than the polar radius.
