STF 227 (Iota Trianguli) is a quadruple star system located 291 light-years away from the Sun. The primary component, designated as A, is a spectroscopic binary consisting of components Aa and Ab. Aa is a G0III spectral class giant star with a mass of 2.5 solar masses and a diameter of 4 solar radii. Ab is also a G5III spectral class giant star with a mass of 2.43 solar masses and a diameter of 1.5 solar radii. Aa and Ab orbit around their center of mass with a period of 14.7 days. Component A is simultaneously a variable star known as TZ Trianguli. The companion, designated as B, is also a spectroscopic binary. Ba is a main-sequence star of spectral class F5V with a mass of 1.58 solar masses. Bb is likely another main-sequence star with a mass of 1.56 solar masses. Components Ba and Bb orbit around their center of mass with a period of 2.2 days. The orbital period of the A and B components is estimated to be 5172 years.

100mm -Iota Trianguli is a suitable object for small telescopes under favorable conditions. During my observation, the conditions were subpar to poor, causing difficulties in resolution. However, during moments of improved seeing, the components were clearly separated at 150x magnification. I observed the primary component as a dark yellow and the companion as orange-yellow. In the literature, the prevailing color description is often orange and blue.
