'astronomy-oriented' originates from the combination of 'astronomy' and the suffix '-oriented', where 'astronomy' is derived from Greek 'astronomia', meaning 'star arrangement', and '-oriented' implies a focus or direction towards something.

'astronomy' changed from the Greek word 'astronomia' and eventually became the modern English word 'astronomy'. The suffix '-oriented' was added to form 'astronomy-oriented'.

Initially, 'astronomy' meant 'star arrangement', but over time it evolved into its current meaning of 'the scientific study of celestial objects'.
