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.

Greater Napanee is a town in southeastern Ontario, Canada, approximately 45 kilometres (28 mi) west of Kingston and the county seat of Lennox and Addington County. It is located on the eastern end of the Bay of Quinte. Greater Napanee municipality was created by amalgamating the old Town of Napanee with the townships of Adolphustown, North and South Fredericksburgh, and Richmond in 1999. Greater Napanee is co-extensive with the original Lennox County.
The town is home to the Allan Macpherson House, a historic 1826 property that is now a museum. Macpherson was a major in the Lennox militia, operated the town's grist and saw mills, as well as the distillery and general store. He served as post master and land agent, operated the first local printing press and helped fund the establishment of many local schools and churches.
