Rimini ( RIM-in-ee, Italian: [ˈriːmini] (listen); Romagnol: Rémin; Latin: Ariminum) is a city in the Emilia-Romagna region of northern Italy and capital city of the Province of Rimini. It sprawls along the Adriatic Sea, on the coast between the rivers Marecchia (the ancient Ariminus) and Ausa (ancient Aprusa). It is one of the most notable seaside resorts in Europe with revenue from both internal and international tourism forming a significant portion of the city's economy. The first bathing establishment opened in 1843. Rimini is an art city with ancient Roman and Renaissance monuments, and is also the birthplace of the famous film director Federico Fellini. The city was founded by the Romans in 268 BC. Throughout Roman times, Rimini was a key communications link between the north and south of the peninsula. On its soil, Roman emperors erected monuments such as the Arch of Augustus and the Tiberius Bridge to mark the beginning and the end of the Decumanus of Rimini.

During the Renaissance, the city benefited from the court of the House of Malatesta, which hosted artists like Leonardo da Vinci and produced works such as the Tempio Malatestiano. The main monuments in Rimini are the Tiberius Bridge and the Arch of Augustus. In the 19th century, Rimini was one of the most active cities on the revolutionary front, hosting many of the movements seeking to achieve Italian unification. In the course of World War II, the city was the scene of numerous clashes and bombings, but also of a fierce partisan resistance that earned it the honour of a gold medal for civic valour. In recent years it has become one of the most important sites for trade fairs and conferences in Italy. As of 31 December 2019, Rimini's urban area was home to 151,200 people, with approximately 325,000 living in the eponymous province, making it the twenty-eighth largest city in Italy.

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.

In its core the Sun currently fuses about 600 million tons of hydrogen into helium every second, converting 4 million tons of matter into energy every second as a result. This energy, which can take between 10,000 and 170,000 years to escape the core, is the source of the Sun's light and heat. When hydrogen fusion in its core has diminished to the point at which the Sun is no longer in hydrostatic equilibrium, its core will undergo a marked increase in density and temperature while its outer layers expand, eventually transforming the Sun into a red giant. It is calculated that the Sun will become sufficiently large to engulf the current orbits of Mercury and Venus, and render Earth uninhabitable – but not for about five billion years. After this, it will shed its outer layers and become a dense type of cooling star known as a white dwarf, and no longer produce energy by fusion, but still glow and give off heat from its previous fusion. The enormous effect of the Sun on Earth has been recognized since prehistoric times. The Sun has been regarded by some cultures as a deity. The synodic rotation of Earth and its orbit around the Sun are the basis of solar calendars, one of which is the predominant calendar in use today.
