A Feb. 23, 1956, Arizona Daily Star ad for Terra Del Sol.

You’ve heard of a playground to the stars. How about a neighborhood to the stars β€” and to the constellations and planets as well?

Street names in the Terra Del Sol subdivision highlight the objects in the night skies, and their often Latin, Greek or Roman names.

From 1955-57, developer Marvin Volk developed the 640-acre project bounded by South Wilmot Road, East 22nd Street, East Golf Links Road and South Kolb Road.

He employed Bill Armstrong, a professional engineer and surveyor, to survey the property. Armstrong was joined by Jack Lamb, who had been an Air Force navigator in the Korean War, to come up with the names.

The subdivision name itself might be a misspelling of β€œTierra Del Sol,” Spanish for β€œLand of the Sun,” or it might have been an intentional combination of Latin and Spanish.

The street names β€” some of which are misspelled β€” and their origins are listed below:

Calle Altair: Also called Alpha Aquilae, Altair is Arabic for β€œflying eagle.” It is the brightest star in the Aquila constellation and the 12th-brightest star in the night sky.

Calle Alkaid: Also known as Eta Ursae Majoris, this blue star is the third-brightest star in the Ursa Major constellation.

Calle Bootis: Also known as Alpha Bootis or Arcturus. Orange in color, it’s one of the five-brightest stars in the sky and the brightest star in the Bootes constellation.

Calle Bellatrix: Bellatrix is a star in the Orion constellation. According to one source, Bellatrix means β€œfemale warrior.”

Calle Betelgeux: Also written Betelgeuse and also called Alpha Orionis, it is the second-brightest star in the Orion constellation. Its derivation is from the Arabic word β€œbat al-jawza,” which means β€œthe giant’s shoulder,” referring to the shoulder of Orion, the mythological Greek hunter.

Calle Castor: Also called Alpha Geminorum, it is a multiple star comprised of six component stars in the Gemini constellation.

Capella is Latin for β€œshe-goat” and is the sixth-brightest star in the night sky and the brightest in the Auriga constellation. It lies 42.2 light-years from Earth. Street signs along this alignment are currently spelled both ways, Cappela and Capella.
