Tähtedesüsteemiga

Tähtedesüsteemiga is the Estonian word for "star system." A star system, in astronomy, is a group of two or more stars that are gravitationally bound to each other and orbit a common center of mass. The most familiar example is our own Solar System, which consists of the Sun and the planets, dwarf planets, asteroids, and comets that orbit it.

While our Solar System is a single star system, many star systems are binary or multiple star systems, meaning they contain two or more stars. These stars can be of similar size and mass, or one star can be significantly larger or smaller than the others. The gravitational interactions between the stars in a multiple star system can lead to complex orbital dynamics.

The study of star systems is crucial for understanding stellar evolution, planet formation, and the distribution of matter in the universe. Astronomers observe star systems through various methods, including direct imaging, spectroscopy, and analyzing the subtle gravitational effects stars have on each other or on any orbiting planets. The variety of star systems observed suggests a wide range of conditions under which stars and planets can form and evolve.
