HD 16028 (original) (raw)
HD 16028 is a star in the constellation Andromeda. Its apparent magnitude is 5.71. Located approximately 225 parsecs (730 ly) distant, it is an orange giant of spectral type K3III, a star that has used up its core hydrogen and has expanded. Double star catalogues list two stars as optical companions. One has a magnitude of 10.9 and is separated by 16.9 arcseconds. It has been suggested it is related to the primary, but parallax measured by Gaia yields a much greater distance for this star in comparison to HD 16028. The other is even fainter and is separated 45 arcseconds from the primary.

Dista 677 anni luce dal sistema solare. (it) HD 16028 är en ensam stjärna belägen i den mellersta delen av stjärnbilden Andromeda. Den har en skenbar magnitud av ca 5,71 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 2 på ca 4,4 mas, beräknas den befinna sig på ett avstånd på ca 730 ljusår (ca 225 parsek) från solen. Den rör sig närmare solen med en heliocentrisk radialhastighet på ca -5 km/s.

По состоянию на 2007 год, радиус звезды оценивается в 24,33 солнечного радиуса. Исходя из отрицательной радиальной скорости, звезда приближается к Солнцу. Планет у HD 16028 обнаружено не было.
