U.S. space agency (NASA) announced the new findings generated Kepler satellite, Thursday, 26/08/2010.
Kepler took a group of alien planets, planets that they were never seen around a star – like planets in the solar system circling the Sun The findings were called Kepler system 9.
Observations of Kepler observatory confirms two Saturn-sized planet orbiting a star – at a distance of about 2300 light years from Earth.
They also reveal the candidate planet is the same size as Earth in the same system.
Why are the candidates? Since its existence has not been confirmed.
So far, astronomers have not confirmed whether there is a potential planet such as Earth – in the sense that you could sustain life. However, the initial analysis says, the planet has 1.5 times the Earth radius.
Continued observations of planetary systems will help answer the question, is there life beyond Earth.
“We hope that within a few days or weeks, we can verify,” said William Borucki, principal investigator at Keppler
NASA’s Ames Research Center as Space pages, loaded 08/26/2010.
For the first time, the analysis of the observations of Kepler also combined with the timing of the transit and radial velocity observations of the mass of alien planets to estimate.
Two of the largest planet in this system, called Kepler, 9b and 9c Kepler – were almost the same diameter. Both have a mass and density as Saturn.
However, the two planets are too close to the star – like the sun, like Mercury, which revolves around the sun. Two planets that would have no life because it is very hot.
Kepler Planet is the planet into two groups announced this week. Previously, an astronomer at the European Space Agency (ESO) announced the discovery of solar system, consisting of seven planets, a distance of 127 light years from Earth.
Earth twins?
The astronauts still have planets similar to Earth than Kepler observatory.
If the existence of third planet like the Earth is no confirmation that the planet would be a ‘smallest planet “known.
“We can say, in terms of physical size, this will be the smallest, but we do not know the weight,” says Matthew Holman, staff director of the department of the theory of astrophysics at the Harvard-Smithsonian Center, where the findings Kepper confirmed.
Keppler unveiled the third planet has a radius of 11.5 times Earth and have orbital periods of about 1.6 days on Earth – less than the Kepler-9b and 9c.
The researchers examined whether the candidates’ twins Earth “orbiting a star similar to two other planets.
“One message of this work is that Kepler progress toward the goal to find a planetary system like our solar system.”
But in terms of eligibility for housing, Kepler-9-system is probably not the place to look for life.
“The planets are unfit for human habitation,” said Holman. Estimated temperature of the two largest planets is very high, around 740 degrees Kelvin (872 degrees Fahrenheit) and 540 degrees Kelvin (512 derajatFahrenheit).
“The temperatures were well above the boiling point of water, would not an uninhabited planet.
