Variable starWhat is 10 Sagitta
10 Sagittae is a yellow G-type variable lodged in the small constellation of the Arrow, near the luminous corridor of the summer Milky Way. Its brightness is not steady: it shifts with a quiet rhythm that modern photometry has managed to follow night after night. Far more luminous and hotter than the Sun, it holds a golden light that surfaces among the densest star fields of the northern summer firmament.
