this is what i got in my ''journey across time '' book
sumerian people watched the skies to learn the best times to plant crops and to hold religious festivals . they recorded the positions of the planets and stars and developed a 12 mouth calendar based on the cycles of the moon
The Sumerians believed in astrology. They thought that events in daily life were affected by the positions of celestial bodies. We are glad they recorded those positions. We can calculate the exact dates of various events in their culture.
Its strength was that it could predict the positions of the planets with pretty good accuracy. Its weakness was that by 1600 the techniques of measuring planets' positions had advanced to the point where discrepancies were noticed in the predictions made with the geocentric model.
Ancient astronomers were able to observe the movements of the planets in the night sky, track their positions relative to the stars, and document their retrograde motion. They also noted patterns in the planets' movements and made connections between their positions and earthly events.
Pictures taken from spacecraft or telescopes can show the positions of the planets relative to the sun over time. By observing these images, we can visually see the planets moving in their orbits around the sun, as their positions change in a predictable pattern. This visual evidence supports the heliocentric model proposed by Copernicus, where the sun is at the center of our solar system and the planets revolve around it.
Gravity and heat.
The Sumerians recorded the positions of the stars and planets and develop a calendar for a couple of reasons. First they believed in a form of astrology where local events could be predicted understanding the heavens. Also, it helped them tell the best time of the year to plant crops.

A calendar of the planets' positions is called an Almanac or an Ephemeris.

They were curious about what they saw, and the techniques they developed led eventually to the development of science.

All the planets move constantly in their orbits around the Sun, so the apparent positions of the planets in the sky is also constantly changing. I recommend the Stellarium planetarium program.
The astronomer Tycho Brahe used large metal instruments such as quadrants and sextants to accurately measure the positions of the planets in the late 16th century. His observations were crucial for later astronomers, including Johannes Kepler, to develop their understanding of the solar system.
The sumerians were the first to leave evidence that they were aware of other planets.
Only Uranus and Neptune were not known to the Sumerians, and required telescopes in order to be discovered.
