@holvek: A binary star system consists of two stars gravitationally bound to each other, orbiting around a common center of mass. These systems are incredibly common in our galaxy, with astronomers estimating that about half of all stars (including the famous Sirius) have a stellar companion. The brighter star in the pair is called the primary, while its partner is known as the secondary or companion. Depending on their distance from Earth and orbital alignment, scientists classify them into different types. Some pairs can be easily separated with a telescope (visual binaries), others are detected by changes in brightness when one star passes in front of the other (eclipsing binaries), and the closest pairs are identified only by shifts in their light spectrum (spectroscopic binaries). Studying these systems is of fundamental importance to astrophysics. By observing the precise orbital motion of the stars, scientists use the laws of gravity to directly calculate stellar masses. This is practically the only reliable method to determine the exact weight of distant cosmic bodies and understand how they evolve over time. #astrophysics #experiment #spacetok #fact

я помню когда сказал однокласснику что солнечная система не крутится на месте а летит в космосе по спирали он мне не поверил
