History of Greek Astronomy
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).
When did Greek astronomy start?
Greek thinking about the motion of the planets began by about 400 bce. Eudoxus of Cnidus constructed the first Greek theory of planetary motion of which any details are known.
Who discovered Greek astronomy?
Who is the Father of Greek Astronomy? Hipparchus of Nicea (l.c. 190-c. 120 BCE) is considered the Father of Greek Astronomy for his contributions to the science including accurate models of planetary motion.
Is astronomy a Greek origin?
Astronomy (from Greek: ??????????, literally meaning the science that studies the laws of the stars) is a natural science that studies celestial objects and phenomena.
What discoveries did Greek astronomers make?
Four amazing astronomical discoveries from ancient Greece

Why was astronomy important to the Romans?
The Romans were very interested in astronomy, but perhaps even more in astrology. They wanted to know what the movement of the constellations meant for them. Thrasyllus, born in Egypt, was the personal astrologer of emperor Tiberius. He predicted that Tiberius would become the new emperor.
Why is Greek astronomy important?
The ancient Greeks were some of the first people to study the sky and understand astronomy. They realized the Earth was a sphere, or a three-dimensional circular object, and tried to measure its size. They also created an idea of a geocentric solar system in which everything orbits around the Earth.
How did astronomy start?
The first documented records of systematic astronomical observations date back to the Assyro-Babylonians around 1000 BCE. From this cradle of civilisation in Mesopotamia in the southern part of present-day Iraq astronomers had built up knowledge of the celestial bodies and recorded their periodic motions.

What are the 4 types of astronomy?
We can divide astronomy into 4 sub-fields:
- ASTROPHYSICS: Applying the laws of physics in space.
- ASTROMETRY: Mapping celestial bodies.
- ASTROGEOLOGY: Examining rocks, terrain and material in space.
- ASTROBIOLOGY: Searching for life outside Earth.
What are the 2 types of astronomy?
In the past century or so, astronomy has been broadly split into two camps observational astronomy (using telescopes and cameras to collect data about the night sky) and theoretical astronomy (using that data to analyze, model and theorize about how objects and phenomena work).
Who is the father of astronomy?

How was astronomy used in ancient times?
Ancient sailors used stars and constellations to guide their travels. Polynesians, for example, sailed among the Pacific Ocean islands by watching stars. To explain why planets seemed to change direction, Ptolemy used old calculations by Hipparchus to understand planetary motion.
Who discovered Parallax?
The first successful measurements of stellar parallax were made by Friedrich Bessel in 1838 for the star 61 Cygni using a heliometer.
Did the Romans discover the planets?
The Romans named the brightest planet, Venus, for their goddess of love and beauty. Two other planets, Uranus and Neptune, were discovered after the telescope was invented in the early 1600s.
What did Greeks believe about the stars?
The constellations, as described in Greek mythology, were mostly god-favoured heroes and beasts who received a place amongst the stars as a memorial of their deeds. They were regarded as semi-divine spirits–living, conscious entities which strode across the heavens.
Who was the first person to study astronomy?
TELESCOPES. An astronomical telescope uses lenses or mirrors to gather and focus the light from distant objects. This makes it easier to study them in detail. The first person to observe the heavens using a telescope was the Italian scientist Galileo Galilei in 1609.
How did astronomy begin answer?
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.
Who made the first star map?
So far as we know, the first people to map the positions of stars were the Chinese astronomers Shi Shen, Gan De and Wu Xian in the third and fourth century BC.
Who is the father of trigonometry?
The first known table of chords was produced by the Greek mathematician Hipparchus in about 140 BC. Although these tables have not survived, it is claimed that twelve books of tables of chords were written by Hipparchus. This makes Hipparchus the founder of trigonometry.
Who discovered the diameter of the Earth?
The first person to determine the size of Earth was Eratosthenes of Cyrene, who produced a surprisingly good measurement using a simple scheme that combined geometrical calculations with physical observations. Eratosthenes was born around 276 B.C., which is now Shahhat, Libya. He studied in Athens at the Lyceum.
