| | Sun - Wikipedia, the free encyclopedia |
 | | Isaac Newton observed the Sun's light using a prism, demonstrating empirically that it was composed of light in many constituent colours. | | | With respect to the fixed stars, the Sun appears from Earth to revolve once a year along the ecliptic through the zodiac, and so the Sun was considered by Greek astronomers to be one of the seven planets (Greek planetes, "wanderer"), after which the seven days of the week are named in some languages. | | | The concept of heliocentrism, which locates the Sun at the centre of the solar system, was first recorded in ancient India by Yajnavalkya (circa 9th century BC) in his work Shatapatha Brahmana, which referred to the Earth as a sphere and to the Sun as the "centre of spheres". |

| | Although the spectrum of the sun had been observed as early as 1666 by the English mathematician and scientist Sir Isaac Newton, the accuracy and detail of Fraunhofer's work laid the foundation for the first attempts at a detailed theoretical explanation of the solar atmosphere. | | | Because of its proximity to the earth, and because it is such a typical star, the sun is a unique resource for the study of stellar phenomena. | | | The sun was finally viewed as a dynamic, evolving body, and its properties and variations were thus able to be understood scientifically. |

| | Dr. SOHO's FAQ: The Sun |
| | The Sun is basically a very ordinary star, about mid-way through its "life cycle." It is a dwarf star (astronomers call stars either "giants" or "dwarfs" - the normal stars are "dwarfs") with a surface temperature of about 6,000 degrees Kelvin. | | | The Sun's magnetic field is much more complicated than the simple dipole field of the Earth, and so it does not really have a well-defined "magnetic axis". | | | The Sun is not brighter or darker (in visible light) than it was 20 years ago. |

The Years of the Sun began towards the end of the First Age of the Children of Iluvatar and continued through the Second, Third, and part of the Fourth in Tolkien's stories. | | | They begin with the first sunrise in conjunction with the Return of the Ñoldor to Middle-earth, and last until the present day. | | | Tolkien estimated that we are now living in the sixth or seventh age. |
