Sun

The Sun (in Greek: Helios, in Latin: Sol) is the star at the center of the Solar System and is by far the most important source of energy for life on Earth. It is a nearly perfect spherical ball of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process. Its diameter is about 109 times that of Earth, and it has a mass about 330,000 times that of Earth, accounting for about 99.86% of the total mass of the Solar System.About three quarters of the Sun's mass consists of hydrogen; the rest is mostly helium, 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 spectral class and it is informally referred to as a yellow dwarf. It formed approximately 4.567 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 increasingly hot and dense, eventually initiating nuclear fusion in its core. It is thought that almost all stars form by this process.

Moon

The Moon (in Greek: σελήνη Selene, in Latin: Luna) is Earth's only natural satellite. It is one of the largest natural satellites in the Solar System, and, among planetary satellites, the largest relative to the size of the planet it orbits (its primary). It is the second-densest satellite among those whose densities are known (after Jupiter's satellite Io).

The Moon is thought to have formed approximately 4.5 billion years ago, not long after Earth. There are several hypotheses for its origin; the most widely accepted explanation is that the Moon formed from the debris left over after a giant impact between Earth and a Mars-sized body called Theia.

The Moon is in synchronous rotation with Earth, always showing the same face with its near side marked by dark volcanic maria that fill between the bright ancient crustal highlands and the prominent impact craters. It is the second-brightest regularly visible celestial object in Earth's sky after the Sun, as measured by illuminance on Earth's surface. Although it can appear a very bright white, its surface is actually dark, with a reflectance just slightly higher than that of worn asphalt. Its prominence in the sky and its regular cycle of phases have, since ancient times, made the Moon an important cultural influence on language, calendars, art, and mythology.

Pokémon

Pokémon (ポケモン, Pokemon, /ˈpoʊkeɪˌmɒn/ POH-kay-mon) is a media franchise owned by The Pokémon Company, and created by Satoshi Tajiri in 1995. It is centered on fictional creatures called "Pokémon", which humans known as Pokémon Trainers catch and train to battle each other for sport.

The franchise began as a pair of video games for the original Game Boy, developed by Game Freak and published by Nintendo. The franchise now spans video games, trading card games, animated television shows and movies, comic books, and toys. Pokémon is the second-most successful and lucrative video game-based media franchise in the world, behind only Nintendo's Mario franchise.

The franchise celebrated its tenth anniversary in 2006. Cumulative sales of the video games (including home console games, such as Hey You, Pikachu! for the Nintendo 64) have reached more than 200 million copies. In November 2005, 4Kids Entertainment, which had managed the non-game related licensing of Pokémon, announced that it had agreed not to renew the Pokémon representation agreement. Pokémon USA Inc. (now The Pokémon Company International), a subsidiary of Japan's Pokémon Co., now oversees all Pokémon licensing outside of Asia. As of 2013, the Pokémon media franchise has grossed revenues of ¥4 trillion worldwide (equivalent to US$37.76 billion). The brand earned $2 billion in 2014 alone.
