[[ਪ੍ਰੌਗਜ਼ਿਮਾ ਸੈਂਚੁਰੀ]] ([[ਲੈਟਿਨ]] ਸ਼ਬਦ proxima ਦਾ ਅਰਥ ਹੈ “ਇਸ ਤੋਂ ਅਗਲਾ” ਜਾਂ “ਇਸਦੇ ਨਜ਼ਦੀਕ”), [[ਸੈਂਚਰਸ]] ਦੇ [[ਤਾਰਾ-ਸਮੂਹ]] (ਕੱਸਟੈਲੇਸ਼ਨ) ਦੀ [[ਸੂਰਜ]] ਤੋਂ ਲੱਗਪਗ 4.24 [[ਪ੍ਰਕਾਸ਼-ਸਾਲ]] ਨਜ਼ਦੀਕ ਇੱਕ [[ਰੈੱਡ ਡਵਾਰਫ]] [[ਤਾਰਾ]] ਹੈ। ਇਹ 1915 ਵਿੱਚ [[ਦੱਖਣੀ ਅਫ੍ਰੀਕਾ]] ਵਿਖੇ [[ਯੂਨੀਅਨ ਓਬਜ਼ਰਵੇਟਰੀ]] ਦੇ ਡਾਇਰੈਕਟਰ ਸਕੌਟਿਸ਼ [[ਖਗੋਲ ਵਿਗਿਆਨੀ]] [[ਰੌਬਰਟ ਇਨੱਨਸ]] ਦੁਆਰਾ ਖੋਜਿਆ ਗਿਆ ਸੀ, ਅਤੇ ਸੂਰਜ ਤੋਂ ਸਭ ਤੋਂ ਨਜ਼ਦੀਕੀ ਤਾਰੇ ਵਜੋਂ ਜਾਣਿਆ ਜਾਂਦਾ ਹੈ, ਭਾਵੇਂ ਇਹ [[ਨੰਗੀ ਅੱਖ]] ਨਾਲ ਦੇਖਣ ਲਈ ਬਹੁਤ ਜਿਆਦਾ ਫਿੱਕਾ ਹੈ, ਜਿਸਦਾ ਸਪਸ਼ਟ ਮੁੱਲ 11.05 ਹੈ। ਬਾਇਨਰੀ [[ਅਲਫਾ ਸੈਂਚੁਰੀ]] ਰਚਣ ਵਾਲੇ ਦੂਜੇ ਅਤੇ ਤੀਜੇ ਨਜ਼ਦੀਕੀ ਤਾਰੇ ਤੋਂ ਇਸਦੀ ਦੂਰੀ 0.237 ± 0.011 ly (15,000 ± 700 AU) ਹੈ। ਸੰਭਾਵਨਾ ਹੈ ਕਿ [[ਪ੍ਰੌਗਜ਼ਿਮਾ ਸੈਂਚੁਰੀ]], [[ਅਲਫਾ ਸੈਂਚੁਰੀ]] A ਅਤੇ B ਨਾਲ ਇੱਕ ਤਿੱਕੜ (ਟ੍ਰਿਪਲ) [[ਤਾਰਾ ਮੰਡਲ]] ਦਾ ਹਿੱਸਾ ਹੋ ਸਕਦਾ ਹੈ, ਪਰ ਇਸਦੀ [[ਔਰਬਿਟਲ ਸਪੀਡ]] 500,000 ਸਾਲਾਂ ਤੋਂ ਵੀ ਜਿਆਦਾ ਹੋ ਸਕਦੀ ਹੈ।
