Our Earth, wood, fire and Earth, Uranus, Neptune, shared the eight planets orbit the Sun, plus a myriad of small celestial bodies and dust to form a planetary system. In this qianyige the Sun in the Milky Way Galaxy, almost qianyige and similar planets in our solar system, that is, almost every star has a planet moves around the work, astronomers called them "exoplanets" (Extra Solar planet--Exoplanet).
Do not think that extrasolar planets so far and we do not see, in fact, on a clear night of pure NET, looked up and saw hundreds of thousands of stars, extrasolar planets exist around half, with many waiting to be discovered. In 1995, astronomers have found the first Exoplanet: Pegasus 51B (Peg 51B), which is around 51 Pegasi 5 stars. Just 20 years past, astronomers around the more than 1000 stars, found about 2000 extrasolar planets, and this still continues.
Star in the night sky, by your name
There are more than 10 early detection systems, it has been very thorough. They each have a few planets spinning? Is 2 or 3, or even 5 stars. Both look like? Is like the Earth's rocky surface, also like Jupiter's "big balloon" (gas). How far is it from their respective Sun? Is like mercury in our solar system was scorched, or like a few months ago probe to flyby, billions of miles away from the Sun as Pluto. Is it possible for the survival of life on Earth a planet? Each planetary system and how far away from us? Have been very clear, but only short of an interesting name.
In addition, more than half of the stars in the night sky are orbiting binary star form with each other, and found that many also have planets around binary star system. The "three"? Liu's science fiction novel of the three-body awarded the 2015 Hugo Awards, which describes the three-star, a planet that revolves around three stars is it really possible? Compared to read the three friends remember a star Cheng Xin Yun Tianming sent, and what a romance, although in reality we cannot send to send a top star, but you can name!
In September 2014, the International Astronomical Union (IAU) announced on its official Web site to call for extrasolar planetary systems around the world for the first time names NameExoWorlds of activities, object is named by December 31, 2008 260 extrasolar planetary system discovered altogether 305 planets, astronomical organizations involved in registration to the world collection name.
Official Web:
http://nameexoworlds.iau.org/
In this 260 planetary systems, organizations involved in registration and vote together the final 20 to be named in planetary systems, each system detailed information already on the above website, you can see all of these planetary systems in which constellation, how bright a star is, how big is the planet, far from their stars and so on. Each system, there are astronomical organizations from around the world submitted by naming, as long as you log in the active Web site, you can support of extrasolar planetary system named precious votes on the proposal!
The proposal of China
Submitted by each organization can only select a system named, but in order to make these pioneer several planetary systems in human history, with the names of Chinese culture, including Hong Kong, Macau S.A.R. and Taiwan more than 10 astronomical organizations, are involved in the registration and naming proposals were submitted. We will also introduce China collected three proposals:
1. Name Organization: Tsinghua University student Astronomical Society
System name: 18 Delphini (18th, dolphins)
Star name: Nie Er (NIE)
Planet names: Shengshi (poems)
Name: Tsinghua University 2011 undergraduate Xu Xiangyu.
We chose Dolphin Northern constellations of the milky way next to a small and cute, the 18th, as shown in the figure. Dolphin takes its name from a famous Greece myths is the story of poet and singer yaliweng. Yaliweng is Collins of rulers Periander of Palace musicians, he for won music game and get many wealth, but also are because wealth makes he in from Taranto home of journey in the was sailor of murder, yaliweng in died Qian pleaded again sing a song elegy, sing finished Hou he decided to jumped into sea in the, but he eventually was a only by he wonderful song moved of Dolphin saved up, and put he sent back has Greece of home. This is a great, filled with high quality of musicians, his fate to rewrite because of his musical talent. So we want a Chinese musician to name Delphinus, the star.
NIE is a famous modern musician, create many wonderful works, he is the composer of the anthem of the national anthem, he is a talented, has a noble patriotic musician. NIE er at the age of 23 drowned, though not, as legend yaliweng is saved by dolphins, but as a symbol of the national spirit will live forever in the hearts of the Chinese people, as a musician, he made his own contribution in the world anti-fascist war, and by people around the world to commemorate. Therefore we propose to 18Del name "NIE".
Since the dolphins with a musical theme, stars in the name of NIE er, so planet we are going to the theme music for, and Chinese music as its theme. China's oldest songs from the book of songs. Poems, also called "six poems" refers to the book in the song of songs without words, six poems, only has the title not writing as a doors song, Word temporarily spectrum. Due to different languages, the lyrics maybe different all over the world, but the lyrics are common around the world, music, pure music enough to impress everyone. So I chose "poems" as name of the planet, dedicated to the world of tribute from China!
2. Name Organization: stars edge mountain
System name: 42 Draconis (42nd, the Draco constellation)
Star name: Taihang (too)
Planet names: Dongling (Dong Ling)
This two a name for everyone should is is familiar of has, too line mountain is China East area of important mountains and geographic line, is China terrain second stepped of East margin, is was called "Zhongyuan of Ridge" of North important mountains, is located in Shanxi province and North plain Zhijian, longitudinal across Beijing, and Hebei, and Shanxi, and Henan 4 province, and city, is northeast-southwest to, stretches more than 400 more than km. The Taihang mountains in North China amateur ideal place for stargazing and Taihang mountains more than veins--dongling is 2303 meters above sea level is the highest peak in Beijing. Dongling mountain far away from the light pollution of the city, towering above the smog, is one of the best stars in Beijing. Later look at selected on the Taihang mountains "Taihang" Star, is also a wonderful experience!
3. Name Organization: Weihai, Shandong University Astronomical Society
System name: XI Aquilae (Aquila ξ star)
Star name: Cradle (cradle)
Planet name: Magpie (magpie)
We named this star cradle star. The name comes from the legend of myth and legend in ancient China. According to legend, Niu lang and Zhi nu are lovers. But they were separated by the Galaxy to never. The star represents, Niu lang and Zhi nu is one of the two children. Chinese Valentine's day every year, cowboy with a pole with two children through the milky way to see his wife. So we named this star cradle means for carrying them in the cradle of love, and also carries the longing for a better life.
We want to choose "Magpies" as our planet named. Niu lang and Zhi nu are a couple just mentioned, but their fate and love are such ruthless interference by the West. Although Galaxy ruthlessly separated both ends they, even though life ups and downs life's ups and downs, their love is solid. Every Chinese will have their magpies, gathered in the air, to build a bridge with their bodies, so they reunited once a year. So the Magpies this name evokes every man's emotional resonance, encourages people to cherish true love bravely. Magpie is a symbol of good luck in Chinese culture, the "magpie" star will convey good wishes from China to the world!
Proposal summary
In summary, the first is dolphins 18, 250 light years away, a star of Visual magnitude 5.5, has an orbital period of approximately 1000 day 10 times times the mass of Jupiter, the gas giant planets, the solar system is like the position of the asteroid belt has a large Jupiter. In the night sky to find images of dolphins along the map will soon be able to find this star! Naming stars "NIE" planets "poems", inspired by dolphins and court musician of Greece myths. Programme from Tsinghua University student Astronomical Society.
Second is the Draco 42, about 300 light-years from us, is a visual magnitude of 5 star and its planet is about 4 times the mass of Jupiter, distance stars 1.2 astronomical units, if the solar system is what we run into Earth orbit position of Jupiter! Find great Draco in the night sky, close to the Dragon's neck down 3 star Sky Chefs can find Draco 42. Naming stars "Taihang" planets "Eastern spirit", towering stems from this stretch for hundreds of kilometers in North China's Taihang mountain and a famous mountain in dongling. Program from: Star mountain edge.
Aquila is the third the ξ, approximately 180 light-years away from us, Visual magnitude 4.7, which planet is a 3 times times the mass of Jupiter, the gas giant planets, star of 0.68 astronomical units. Solar system like Jupiter Venus placed in our location. In the night sky, this star is close to the famous Altair 1 place. Naming stars for "cradle", the planet "Magpies", Altair inspiration is derived from it are very close to the ancient Chinese myth of the cowboy lug pole cradles with Weaver. Program from: Weihai, Shandong University Astronomical Society.

Due to the event's official Web site in English, Chinese name natural disadvantages. Only in our common efforts, in order to let the world hear the voice of China, human in the end to leave China named an extrasolar planet for the first time mark! We educate public micro-letter number of the Astronomical Society astrotsinghua and SINA weibo @ Tsinghua University Astronomical Society, as well as micro-Star edge mountain letter public, "Star edge mountain" and SINA micro-blog star @ rim mountain team will continue to monitor this activity and look forward to your participation!
