Abstract
A historical analysis of the challenges faced by early astronomers in measuring the temperature of the sun, highlighting the limitations of their instruments and methods. This document provides a detailed examination of the impact of these limitations on the accuracy of their results. Relevant to the study of astronomy and the history of science.

[...] Temperature and solar spectrum 1. Based on documents 1 and astronomers evaluated the temperature of the sun with such little precision because physicists used measurement instruments that were not precise enough. Furthermore, they did not use the same instruments because their laws, although just, were different. They then obtained different and generally false results. 2. According to document the SOLAR-SOLSPEC instrument was specifically designed to record the solar spectrum. It has a very high precision and that is why the thermal spectrum of the Sun recorded by the ISS space station serves as a reference. [...]
