How can accurate orbits and masses be determined in astronomy?

In summary, astronomy is the scientific study of celestial objects and phenomena, while astrology is the belief that the positions and movements of celestial bodies can influence human affairs and personality traits. There are multiple ways to observe the night sky without a telescope, such as naked eye observation, using binoculars, or visiting a local observatory or planetarium. The most famous object in the night sky is the Moon, as it is the closest celestial body to Earth and can be seen with the naked eye. Astronomers use various techniques to measure distances in space, such as parallax, redshift, and the cosmic distance ladder. With a good telescope and dark skies, it is possible to see many other galaxies besides our own Milky Way, such as
