Two planets found outside our solar system peculiar orbital period less than 2 days.
7 <P> European astronomers announced that they discovered the two planets outside our solar system, the period around the star are less than two days, and had most of the observed extrasolar planets are different, they may represent a .new types of planets. .Running around the extrasolar planet of a star observer on Earth would appear to result in periodic slightly dim the brightness of stars. .Astronomers It is through this effect, in the "constellation Carina," the direction of the two newly discovered around distant stars, planets. .The results show that the two were gas planets light years from Earth in 6000 and 1200 light years. .Weight than the planet Jupiter, in which 35%, 10% larger heads, running around a star just 1.43 days a week, and its surface temperature is estimated more than 1,800 degrees Celsius. .Jupiter is almost another planet and weight, an average of 1.69 days per week to run around the star, presumably the surface is also very hot. .Over the past decade, astronomers have found outside our solar system has more than 120 planets, but only one cycle of operation of planets around stars of less than 3 days. .Astronomers say the planet and perhaps the newly discovered planets can be classified as a new category, characterized by their star running around a very short period, its revolution around the star and planets are very close to this. .Astronomers named the planet of such new "very hot Jupiter." .It is estimated that such planets are very rare, the average 2500-7000 may have a star in the existence of such planets around stars. .Astronomers say they currently can not explain how such planets in very close distance around the star operation. .Astronomers have observed about the results of two new planets will be officially published in "Astronomy and Astrophysics" magazine. .</ P>.
