Norwich ( (listen)) is a city in Norfolk, England, about 100 miles (160 km) north-east of London. Located on the River Wensum, it is the county town of Norfolk and traditionally seen as the chief city of East Anglia. Its population in 2019 was estimated at 197,212. The local authority is Norwich City Council. The site of Norwich was settled by the Anglo-Saxons in the 5th–7th centuries, near the former Iceni capital and Roman town of Venta Icenorum. It became established as a town in the 10th century and developed into a prominent centre for trade and commerce in East Anglia. Norwich Cathedral and Norwich Castle were founded soon after the Norman Conquest in 1066. Norwich was granted city status by Richard the Lionheart in 1194.

The Sun is the star at the center of the Solar System. It is a nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy mainly as light and infrared radiation. It is by far the most important source of energy for life on Earth. Its diameter is about 1.39 million kilometres (864,000 miles), or 109 times that of Earth, and its mass is about 330,000 times that of Earth. It accounts for about 99.86% of the total mass of the Solar System.
Roughly three quarters of the Sun's mass consists of hydrogen (~73%); the rest is mostly helium (~25%), with much smaller quantities of heavier elements, including oxygen, carbon, neon, and iron.The Sun is a G-type main-sequence star (G2V) based on its spectral class. As such, it is informally and not completely accurately referred to as a yellow dwarf (its light is closer to white than yellow). It formed approximately 4.6 billion years ago from the gravitational collapse of matter within a region of a large molecular cloud. Most of this matter gathered in the center, whereas the rest flattened into an orbiting disk that became the Solar System. The central mass became so hot and dense that it eventually initiated nuclear fusion in its core. It is thought that almost all stars form by this process.
