HD 175535 is a

mas.[1] It is moving further from the Earth with a heliocentric radial velocity of +8.5 km/s.[2]

The binary nature of this system was announced by

semimajor axis and i is the (unknown) orbital inclination.[4] This indicates that the actual semimajor axis is larger than 0.49 AU.[10]

The visible component appears to be an

Sun's luminosity from its enlarged photosphere at an effective temperature of 5,024 K.[2]
