Ancient Indian Astronomical Achievements
Early Observations and Calendar Systems: The Vedas contain references to celestial movements and timekeeping, including a 360-day year divided into 12 months. The Vedanga Jyotisha (one of the earliest Indian texts on astronomy) provided rules for tracking the Sun and Moon for calendrical purposes.
Planetary Recognition: The Navagraha system clearly identifies nine celestial bodies: the Sun, Moon, Mars, Mercury, Jupiter, Venus, and Saturn, along with Rahu and Ketu (the lunar nodes). This demonstrates an awareness of these bodies and their perceived influence.
Sophisticated Mathematical Models: Indian astronomers developed advanced mathematical techniques for calculating planetary positions, predicting eclipses, and understanding celestial phenomena.
Aryabhata (5th-6th century CE): A monumental figure, Aryabhata proposed a heliocentric model where the Earth rotates on its axis and planets orbit the Sun. He also accurately explained the cause of eclipses (Earth's shadow on the Moon, Moon's shadow on the Earth), correcting the mythological explanations. He gave a highly precise value for pi and developed sine functions crucial for astronomy.
Varahamihira (6th century CE): His Pancha Siddhantika summarized five major astronomical systems, showing a comprehensive understanding of prevailing theories.
Brahmagupta (7th century CE): His works significantly influenced Arab astronomy and included detailed descriptions of astronomical instruments.
Concepts of Gravity (Proto-Gravity): Some Indian texts from the 6th century suggested that the same force that held objects to the Earth also held celestial bodies in place, hinting at a proto-gravitational theory long before Newton.
Transmission of Knowledge: Indian astronomical and mathematical knowledge, including the decimal place-value system and the concept of zero, significantly influenced Islamic and later European astronomy through various exchanges.
Why European Astronomers Received More Credit
Despite these profound contributions, there are several reasons why European astronomers are often credited with the "discovery" and systematic description of the planetary system in modern historical narratives:
The Scientific Revolution and Methodology:
Empirical Observation and Experimentation: The European Scientific Revolution (16th-18th centuries) emphasized a rigorous empirical approach, systematic experimentation, and detailed observational data to prove theories. While ancient Indian astronomers made keen observations, the European emphasis on a new scientific method, often involving instruments like the telescope (Galileo), was a distinguishing factor.
Mathematical Proof and Mechanistic Universe: European astronomers like Copernicus, Kepler, and Newton built mathematical models that not only described planetary motions but also provided a mechanistic explanation for them (e.g., Kepler's laws of planetary motion, Newton's law of universal gravitation). This went beyond mere description to explain why planets moved the way they did, based on universal physical laws. This laid the foundation for modern physics and astronomy.
Distinction between Astronomy and Astrology: While ancient Indian astronomy was often intertwined with astrology (Jyotisha), the European Scientific Revolution increasingly sought to separate scientific inquiry from religious or astrological interpretations.
Heliocentric Model and Its Acceptance:
While Aryabhata proposed a heliocentric model, it did not become the widely accepted or dominant view in India for centuries. The geocentric model (Earth at the center) remained prevalent in many traditional Indian astronomical schools.
In Europe, Copernicus's heliocentric model (16th century), followed by Galileo's telescopic observations and Kepler's laws, eventually overthrew the long-held Ptolemaic geocentric view, leading to a paradigm shift in scientific thought that had a profound impact globally.
Documentation and Dissemination:
The way knowledge was documented and disseminated differed. While Indian texts were often in Sanskrit and sometimes highly specialized, European scientific works, especially during and after the Renaissance, became more widely accessible through printing and translation, facilitating wider engagement and debate.
Colonialism and Eurocentrism:
During the colonial era, European powers dominated global narratives, including scientific history. This led to a Eurocentric bias in the recording and dissemination of scientific achievements, often downplaying or overlooking contributions from non-European civilizations. Knowledge from colonized regions was frequently extracted and re-contextualized under European names.
Focus of the Navagraha Shlokas:
The Navagraha Shlokas, while demonstrating knowledge of the planets, are primarily devotional and astrological in nature. Their purpose is often to appease the planetary deities for personal well-being, rather than to provide a purely scientific, observational, or mechanistic explanation of their physical properties or orbital dynamics in the modern sense. They recognize the influence of these bodies but don't typically delve into the precise mathematical derivations of their orbits or physical characteristics in the same way European astronomy did centuries later.
In conclusion, ancient India undoubtedly possessed a rich astronomical heritage, and the Navagraha Shlokas are a testament to their early recognition of the planets. However, the "credit" for describing the planetary system in the context of modern science often goes to European astronomers due to their development of a new scientific methodology, the widespread acceptance and rigorous mathematical proofs of the heliocentric model, and historical factors related to global power dynamics and the dissemination of knowledge. There is a growing effort in modern scholarship to acknowledge and integrate the diverse global contributions to astronomy, including the significant advancements made in ancient India.

The Navagraha shlokas of ancient Bharat...
The Navagraha Shlokas are a set of Sanskrit verses dedicated to the nine celestial bodies or "grahas" (planets) in Hindu astrology. These grahas are believed to influence human life and destiny. Chanting these shlokas is a common practice to appease the planets and mitigate any negative effects they might have according to one's horoscope.
Origin of Navagraha Shlokas
The most widely known and recited Navagraha Stotram (hymn) is attributed to Maharishi Vyasa. Vyasa is a revered sage in Hinduism, traditionally credited with compiling the Vedas and authoring the Mahabharata, including the Bhagavad Gita. The Navagraha Stotram, as composed by him, is a succinct yet profound prayer consisting of nine verses, each dedicated to one of the nine grahas.
While the concept of planetary influence and their worship has ancient roots in Vedic astrology (Jyotisha), the specific Navagraha Stotram by Vyasa serves as a popular and accessible means of veneration. The practice of propitiating these celestial bodies is deeply embedded in Hindu traditions, and most Hindu temples worldwide have a dedicated section for the Navagrahas.
