Rho3 Arietis

Rho3 Arietis (Rho3 Ari, ρ3 Arietis, ρ3 Ari) is the Bayer designation for a star in the northern constellation of Aries. It is faintly visible to the naked eye with an apparent visual magnitude of 5.63.[2] Based upon an annual parallax shift of 28.29 mas,[1] this star is located at a distance of approximately 115 light-years (35 parsecs) from Earth.

For other stars with this Bayer designation, see ρ Arietis.

This is an astrometric binary system.[7] The visible component is an F-type main sequence star with a stellar classification of F6 V.[3] It is around 2.4 billion years old[4] and has a high abundance of elements other than hydrogen and helium when compared to the Sun.[5]

Name

This star, along with δ Ari, ε Ari, ζ Ari, and π Ari, were Al Bīrūnī's Al Buṭain (ألبطين), the dual of Al Baṭn, the Belly.[8] According to the catalogue of stars in the Technical Memorandum 33-507 - A Reduced Star Catalog Containing 537 Named Stars, Al Buṭain were the title for five stars : δ Ari as Botein, π Ari as Al Buṭain I, ρ3 Ari as Al Buṭain II, ε Ari as Al Buṭain III dan ζ Ari as Al Buṭain IV[9]

gollark: You would, at least, mildly worsen prospects for developing another game.
gollark: Idea: start making a game now, then wait 20 years and actually do any of the work, so I can claim I worked on it for 20 years.
gollark: You could use that to argue that if you, say, start up a competing brick company and drop the market price of bricks, you are stealing from other brick companies.
gollark: *However*, that doesn't work on other stuff.
gollark: Anyway, ignoring the "inherent", you raise an interesting point regarding it diminishing the value of other copies.
