SIMBAD data

HD 155035 is a star in the constellation Ara, the Altar. It is located at a distance of approximately 1,450 light-years (450 parsecs ) [2] from Earth and has an apparent visual magnitude of 5.92, [3] making it is faintly visible to the naked eye. This is a red giant star with a stellar classification of M1.5 III. [4]

The Hipparcos data revealed that HD 155035 is a variable star. It was given its variable star designation, V854 Arae, in 1999. [10] It's an irregular variable that changes brightness over an amplitude range of 0.12 magnitudes. [11]
