Ara

Ara is a constellation in the southern sky. The constellation name comes from the Latin for 'altar'. It was first described by the Greek astronomer Ptolemy in the 2nd century. There are 8 main stars in the constellation. The Stingray Nebula is in Ara.

In Stargate Atlantis, Ara was a member of the Satedan military who was captured by the wraith, and eventually became a wraith worshiper. She was killed by Rakai, one of her fellow wraith worshipers.  In Stargate SG-1, Ara was the name of a platform in the shape of the Ori symbol for Origin, upon which heretics were burned.

In Dragonlance, Ara Kano was a leader of the town Pirim.

Ara Tribe is a tribe in the StarCraft Universe.

Project Ara is a Google initiative to create modular smartphones.
Ara is a genus of macaws.

Although the constellation name is derived from Latin, Ara is also a female Persian name that means 'brings rain', and a male Armenian name from a legendary King, Ara the Beautiful. Ara is sometimes used as a nickname for the Russian name Avrora. It can also be used as a nickname for Arabella.

Ara appears in the SSA's top 1000 girl names from 1900-1918. It's highest rank was in 1901 when it reached #559. It has never reached the top 1000 for boys. It was given to just 49 girls and 7 boys in 2014. Although it's unisex, I think Ara works best for girls due to it's similarity to Ada and Ava. It would be a good choice for parents who like those names but want something a little different.
