Glossary term: 센타우루스자리프록시마별

Description: 알파 센타우리 C로도 불리는 센타우루스자리프록시마별은 태양에서 약 4.24광년(1.302파섹), 즉 약 40조 킬로미터 떨어져 있는 태양에 가장 가까운 별입니다. 이 별은 크기와 질량이 태양보다 작으며, 매우 희미한 적색왜성이기 때문에 맨눈으로는 볼 수 없습니다. 현재까지 프록시마 센타우리 주위를 도는 행성 중 한 개가 확인되었으며, 이 행성은 프록시마 센타우리 b라고 불립니다. 이 행성의 궤도는 생명가능지대에 있어, 표면에 액체 상태의 물이 존재할 가능성이 있습니다. 이 밖에 프록시마 센타우리 c와 d라는 두 개의 후보 행성이 제안되었지만, 아직 확정되지 않았습니다. 프록시마 센타우리는 알파 센타우리 A와 알파 센타우리 B와 함께 중력으로 연결된 삼중성계, 즉 알파 센타우리 항성계를 이루고 있습니다.

Proxima Centauri appears as a bright point with diffraction spikes. Several fainter stars are in the background.

Proxima Centauri, Our Closest Stellar Neighbor

Caption: Hubble's view of Proxima Centauri, a M-type dwarf and the nearest star to our Solar System. While this is the nearest star to the Sun, it was not discovered until 1915 due to its inherent faintness. Despite its proximity, it remains a point-like object in this image as even the closest stars to the Sun are very far away when compared to their physical size.
