Twins of Earth
The astronauts have yet to find planets similar to Earth than Kepler observatory. If the existence of a third planet like the Earth has been no confirmation that the planet could be a ’smallest planet’ known.
“We can say, in terms of physical size, this will be the smallest, but we do not know its mass,” says Matthew Holman, staff director of the division of the theory of astrophysics at the Harvard-Smithsonian Center, which confirmed the findings Kepper. Keppler revealed, this third planet has a radius of 11.5 times the Earth and have orbital periods of about 1.6 days on Earth - shorter than the Kepler-9b and 9c. The investigators are examining whether the candidates ‘twins Earth’ orbiting a star similar to two other planets.
“One message from this work is that Kepler made progress toward the goal to find a planetary system like our solar system.” But in terms of eligibility for habitation, Kepler-9 system is probably not the right place to look for life.
“The planets are as 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 Fahrenheit).
“Temperatures were well above the boiling point of water, then allegedly was not a planet uninhabited.
