<p>The Sun is the star at the center of the Solar System. </p>It is a sphere of plasma, with inner convective movement that generates a magnetic field by means of a dynamo process. It is by far the main source of energy for life on Earth. Its diameter is about 1.39 million kilometers (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 is composed of hydrogen (~73%); the remainder is mostly helium (~25%), with much smaller amounts of heavier elements, including oxygen, carbon, neon, and iron.The Sun is a G-type main-sequence celebrity (G2V) based on its spectral class. As such, it's informally rather than 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. Whereas the remainder flattened into an orbiting disk that became the Solar System, most of this matter gathered in the center. The central mass became dense and so hot that it initiated nuclear fusion. It is believed that almost all stars form by this process.



The Sun fuses about 600 million tons of hydrogen into helium every second, converting 4 million tons of matter into energy every second. This energy, which may take 170,000 and between 10,000 years to escape from its core, is the origin of the Sun's light and heat. When hydrogen fusion in its core has diminished to the point where the Sun is no more 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 orbits of Venus and Mercury, 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 called a white dwarf, and no longer produce energy by fusion, but still glow and give off heat from its previous fusion. The Sun on Earth's effect has been recognized since ancient times, and some cultures as a deity have seen the Sun. Its orbit around the Sun and the synodic rotation of Earth will be the basis of solar calendars, among which is the calendar in use today.

<p>Jupiter is the fifth planet from the Sun and the largest in the Solar System. </p>It's a gas giant with a mass one-thousandth that of the Sun, but two-and-a-half times that of the rest of the planets in the Solar System. Jupiter is one of the objects visible to the naked eye in the night sky, and has been known since before recorded history. It's named after the Roman god Jupiter. Jupiter can be bright for its reflected light to cast shadows, and is on average the natural thing in the night sky after the Moon and Venus, when viewed from Earth. Though helium contains only about a tenth of the number of molecules, jupiter is composed of hydrogen with a quarter of its mass being helium. It may also have a core of elements that are heavier, but like the other giant planets, Jupiter lacks a solid surface that is well-defined. Due to its rapid rotation, the world's shape is that of an oblate spheroid (it has a slight but noticeable bulge around the equator). The outer air is visibly segregated into bands at different latitudes, leading to turbulence and storms across their bounds. A result that is notable is the Great Red Spot, a storm that's known to have been around since at least the 17th century when telescope first saw it.



Surrounding Jupiter is a faint planetary ring system and a magnetosphere. Jupiter has 79 moons, including the four Galilean moons discovered by Galileo Galilei in 1610. Ganymede, the largest of them, has a diameter greater than that of the planet Mercury. Pioneer 10 was the first spacecraft to go to Jupiter, making its closest approach to the planet on December 4, 1973; Pioneer 10 recognized plasma in Jupiter's magnetic field and also found that Jupiter's magnetic tail was nearly 800 million km long, covering the whole distance to Saturn. Jupiter has been explored on a number of occasions starting with the Pioneer and Voyager flyby missions from 1973 to 1979, and by the Galileo orbiter. In February 2007, Jupiter was visited by the New Horizons probe, which used Jupiter's gravity to increase its speed and flex its trajectory en route to Pluto. The most recent probe to visit the planet is Juno, which entered into orbit around Jupiter. Future targets for mining in the Jupiter system include the likely liquid sea of its moon Europa.
