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.

Ashdod (Hebrew: אַשְׁדּוֹד; Arabic: أشدود) is the sixth-largest city and the largest port in Israel accounting for 60% of the country's imported goods. Ashdod is located in the Southern District of the country, on the Mediterranean coast where it is situated between Tel Aviv to the north 32 kilometres (20 miles) away, and Ashkelon to the south 20 km (12 mi) away. Jerusalem is 53 km (33 mi) to the east. The city is also an important regional industrial center.
Modern Ashdod covers the territory of two ancient twin towns, one inland and one on the coast, which were for most of their history two separate entities, connected by close ties with each other. This article deals with these historic towns, including other ancient nearby sites, and modern Ashdod.
The first documented urban settlement at Ashdod dates to the Canaanite culture of the 17th century BCE. Ashdod is mentioned 13 times in the Bible.
