Biratnagar vs Sun

Informations

Biratnagar (Nepali: विराटनगर) is a metropolitan city in Nepal, which serves as the capital city of Province No. 1. With a population of 242,548 as per the 2011 census, it is the largest city in the province and also serves as the headquarters of Morang district. Biratnagar is located 399 km (248 mi) east of the capital, Kathmandu and 6 km (3.7 mi) north of the bordering town of Jogbani in the Indian state of Bihar. The highest peak in the world, Mount Everest, is located 174 km (108 mi) north of the city. Biratnagar was declared a metropolitan city on 22 May 2017, thus pushing the total population to over 240,000 making it the fourth most populated metropolitan city in the country after the urban agglomeration of Kathmandu and Lalitpur, Pokhara, and Bharatpur.

The city is home to the Biratnagar Jute Mills, the first large scale industry of Nepal. It also serves as an entry point to eastern Nepal as well as north-eastern India. Biratnagar is the second Nepalese city, after Janakpur, to have a connection with the Indian Railways and the only city after Birgunj to operate an integrated check post (ICP) on the Indian border. Considered to be the industrial capital of Nepal, the city is also the birthplace of five prime ministers of Nepal, in addition to being host to a number of revolutionary incidents in the country including the first labor strike which led to the anti-Rana movements.

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.
