10 most amazing Exoplanets
The total number of exoplanets in the milky Way galaxy has over 100 billion. Exoplanet is a planet located outside our solar system. Currently, the scientists opened only a small proportion of them. About 10 of the most incredible planets in this post.
The darkest exoplanet – a distant, Jupiter-sized gas giant called TrES-2b.
The measurements showed that the planet TrES-2b reflects less than one percent of light, making it blacker than coal and darker naturally any of the planets of the solar system. Work on this planet, was published in the journal of the Royal Astronomical Society Monthly Notices. Planet TrES-2b reflects less light than black acrylic paint, so this is truly a dark world.
The largest planet ever found in the Universe is TrES-4. It was discovered in 2006 and it is located in the constellation Hercules. The planet is called TrES-4 orbits the star, which is at a distance of about 1,400 light years from planet Earth.
Researchers claim that the detected diameter of the planet by almost 2 times (actually 1.7) larger than the diameter of Jupiter (the largest planet of the Solar system). The temperature of TrES-4 1260 degrees Celsius.
A year on COROT-7b takes just over 20 hours. It is not surprising that the weather in this world, to put it mildly, exotic.
Astronomers have theorized that the planet consists of a molded and solid rocks, not frozen gases that will evaporate under such conditions.Temperature according to scientists drops to +2000 on an illuminated surface to -200 With at night.
Astronomers saw cosmic cataclysm: the star absorbs its own planet, which was in the immediate vicinity. We are talking about the exoplanet WASP-12b. She was discovered in 2008.
WASP-12b, as with most known exoplanets, discovered by astronomers, is the great gaseous world. However, unlike most other exoplanets, WASP-12b revolves around its star at a very close distance – just over 1.5 million kilometers (about 75 times closer than earth is from the Sun).
Huge world WASP-12b have a look at the face of his death, the researchers said. The main problem of the planet – its size. It has grown to such an extent that it can not keep their matter against gravity, home star. WASP-12b takes a matter star with tremendous speed: six billion tons every second. In this case, the planet will be completely destroyed by the star in about ten million years. Space standards, this is quite a bit.
With the help of space telescope astronomers were able to detect the smallest rocky exoplanet, whose diameter is about 1.4 of the diameter of the Earth.
The new planet has received designation Kepler-10b. The star around which it revolves, is at a distance of about 560 light years from Earth in the constellation of the Dragon and similar to our Sun. Referring to the class of “supertall”, Kepler-10b is fairly close to its sun orbit and revolves around just is 0.84 earth days, the temperature it reaches several thousand degrees Celsius. According to the researchers, when the diameter of 1.4 in the diameter of the Earth Kepler-10b has a mass of 4.5 earth.
Object HD 189733b is a planet, similar in size to Jupiter, which revolves around its star at a distance of 63 light-years away. And although this planet is the size of like Jupiter, because of its proximity to its star, it is much hotter than the dominant gas giant in our Solar system. As was found for other hot Jupiter, the rotation of this planet is synchronized with its orbital motion – a planet always facing the star with one side. The period of rotation equal to 2.2 earth days.
Analysis of data on the system Kepler-16 has shown that open it in June 2011, the exoplanet Kepler-16b revolves directly around the two stars. If the observer could be on the surface of the planet, he would have seen rises and sets with two suns, just like the planet Tatooine from the fantastic Saga “Star wars.”
In June 2011, scientists announced that the system is the planet, which received the designation Kepler-16b. After further detailed study, they found that Kepler-16b revolves around the double star system in an orbit that is approximately equal to the orbit of Venus, and makes one revolution for 229 days.
Thanks to the joint efforts of the Amateur astronomers participating in the project Planet Hunters, and professional astronomers were able to discover a planet in a system of four stars. Planet orbit two stars, around which, in turn, treated two stars.
PSR 1257 b and PSR 1257 c
2 the planets revolve around the dying star.
Kepler-36b and Kepler-36c
Exoplanets Kepler-36b and Kepler-36c – these new planets discovered by the Kepler telescope. These unusual exoplanets are strikingly close to each other.
Astronomers have discovered a pair of neighboring etplanet with different densities in orbits very close to each other. Exoplanets too close to its star and are not in the so-called “habitable zone” of star systems, i.e. the zone where liquid water can exist on the surface, but they are not interested in it. Astronomers surprised by the very close proximity of these two very different planets: orbits of the planets are as close as any other previously discovered planets orbit.
