From Greek and Latin 'astra' meaning 'stars,' a name evoking the celestial heavens.
Astra descends from the Latin astrum and Greek astron, both meaning 'star.' The Greek root connects it to the Proto-Indo-European h₂stér, one of the oldest reconstructible words in the Indo-European language family — evidence that humans have been naming the lights in the sky, and themselves after those lights, since before recorded history. The name shares ancestry with asteroid, astronomy, disaster (etymologically 'bad star'), and the constellation names that still anchor our understanding of the night sky.
As a given name, Astra never achieved the mass-market popularity of Star or Stella but has appeared consistently across European naming records, particularly in Latvian and Lithuanian traditions, where star-derived names have deep pagan and folk roots. The Latvian feminine name Astra is particularly common, sometimes also associated with the aster flower — itself named from the Greek for star due to its radiating petals. This botanical connection gives the name an additional layer of natural imagery.
In contemporary naming culture, Astra has gained renewed appeal among parents drawn to celestial names — alongside Luna, Nova, Orion, and Lyra — as space exploration has re-entered the cultural imagination. It carries a certain retrofuturist glamour, feeling both ancient and science-fictional simultaneously. Astra has also appeared in literature and comics as a name for heroines with cosmic powers, reinforcing its association with radiance, scope, and the aspirational gaze upward. For a name so short, it holds a remarkable amount of sky.
