How did astronomy help the Greeks?

In classical Greece, astronomy was a branch of mathematics; astronomers sought to create geometrical models that could imitate the appearances of celestial motions. This tradition began with the Pythagoreans, who placed astronomy among the four mathematical arts (along with arithmetic, geometry, and music).

What is astronomy in simple words?

Astronomy is the study of everything in the universe beyond Earth’s atmosphere. That includes objects we can see with our naked eyes, like the Sun , the Moon , the planets, and the stars . It also includes objects we can only see with telescopes or other instruments, like faraway galaxies and tiny particles.

How did astronomy begin?

The Ancient Greeks developed astronomy, which they treated as a branch of mathematics, to a highly sophisticated level. The first geometrical, three-dimensional models to explain the apparent motion of the planets were developed in the 4th century BC by Eudoxus of Cnidus and Callippus of Cyzicus.

The reason why stars are so important is because they have helped humans navigate through Earth . When it was dark these stars would light up the sky giving people light . In addition stars are very important because they make life on Earth.

Why was the knowledge of the seasons so important to early farmers?

Early farming societies were at the mercy of the seasons. In order for a group of people to sustain a successful farming culture, they needed to come up with accurate ways of predicting when spring would occur (to know when to plant) and when the first frost could be expected (to know when to harvest).
