Based on parallax measurements obtained during the Gaia mission, it is about 457 light-years (140 parsecs) distant from the Sun. NomenclatureHD 161693 is the star's entry in the Henry Draper Catalogue and HR 6618 that in the Bright Star Catalogue. It bore the traditional name Al Ruba, Arabic for "the Camel's Foal", a member of the Mother Camels asterism in early Arabic astronomy.[16] In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN)[17] to catalogue and standardize proper names for stars. The WGSN approved the name Alruba for this star on 1 June 2018 and it is now so entered on the List of IAU-approved Star Names.[14] PropertiesThis star is a A-type main sequence star with a stellar classification of A0 V.[4] References1. ^1 {{cite book |last1=Garfinkle|first1=Robert A. |title=Star-Hopping: Your Visa to Viewing the Universe |date=2008 |publisher=Cambridge University Press |isbn=978-0521598897 |page=183 |edition=2nd |url=https://books.google.com/?id=40JzBYGREL0C&pg=PA183&dq=protecting+%22Mother+Camels%22+Draco#v=onepage&q=baby%20%22Mother%20Camels%22%20Draco&f=false |accessdate=16 October 2016}} [1][2][3][4]2. ^1 2 {{cite web | url=https://www.iau.org/public/themes/naming_stars/ | title=Naming Stars |publisher=IAU.org |accessdate=2018-07-01}} 3. ^1 {{citation | title=HD 161693 -- Star | work=SIMBAD Astronomical Database | publisher=Centre de Données astronomiques de Strasbourg | url=http://simbad.u-strasbg.fr/simbad/sim-id?Ident=HD+161693&submit=submit+id | accessdate=2018-07-01 | postscript=. }} 4. ^1 {{Cite web |url=https://www.iau.org/science/scientific_bodies/working_groups/280/ |title=International Astronomical Union {{!}} IAU |website=www.iau.org |access-date=2018-07-01}} 5. ^{{cite journal|bibcode=2007A&A...474..653V|title=Validation of the new Hipparcos reduction|journal=Astronomy and Astrophysics|volume=474|issue=2|pages=653|author1=Van Leeuwen|first1=F|year=2007|doi=10.1051/0004-6361:20078357|arxiv=0708.1752}} 6. ^{{cite journal|bibcode=2009yCat....102025S|title=VizieR Online Data Catalog: General Catalogue of Variable Stars (Samus+ 2007-2013)|journal=VizieR On-line Data Catalog: B/gcvs. Originally published in: 2009yCat....102025S|volume=1|display-authors=etal|author1=Samus|first1=N.
