There may be upgraded to the moon planet.
<P Align=center> </ P> <P> Technology Channel (tech.) message: If you vote next week, astronomers recently proposed definition of a planet, then things really get weird together. .By then, the asteroid "Ceres" will become the planet. .Pluto's satellite, "Charon" will become a planet. .</ P> <P> However, we are talking about more strange things. .University of California, Santa Cruz in the study of extrasolar planetary scientist Gregory Flynn said the lira, more surprisingly, if the life of the planet and its satellites long enough, the moon is bound to be re-classified as final .planets. .</ P> <P> by the International Astronomical Union (IAU) General Assembly of the new planet definition of standard basic that every round object rotating around the sun is the planet, unless it's orbit around another planet rotation. .But it also produced a huge limit Note: that is, if the center of gravity (called the center of gravity) in the larger objects, but it would be the smaller planetary objects. .This measure will Pluto's moon "Charon" upgraded to the ranks of the planet, but some astronomers have been highly critical. .</ P> <P> But things are much more than that. .Earth's moon was born 40 billion years ago in a catastrophic collision, the initial, very close to the Moon from Earth, but later started getting away. .Moon is currently at an annual rate of about 3.74 cm further away with the Earth. .Right now, the focus of this system within the earth, but this situation will change. .</ P> <P> La Fulin on Space Network, said: "If the earth and the moon is indeed life long enough, then farther and farther from Earth as the moon, its center of gravity beyond Earth will eventually be removed, when the moon has .may be upgraded to a planet. I do not know how then should we call it? "</ P> <P> this hypothesis in the next billions of years can not become a reality. .It is expected that the gradual expansion of the sun into a red giant. .La Fulin and other experts had also said that the sun could eventually be swallowed up and evaporation earth, unless we can find solutions. .As a result, the Earth and the Moon will face a series of assumptions have to survive a catastrophic Caixing. .</ P> <P> other astronomers also noted that there may be found outside the solar system Samsung system. .If they are round shape and has a certain center of gravity, then according to the new definition, they will be called the three planetary systems. .</ P> <P> following is even more strange </ P> <P> astronomers expected to find hundreds of stars outside our solar system Pluto-sized objects. .La Fulin explained that if one satellite is circular, and has a certain eccentric orbit - meaning the two objects from a point very close, and then widening the distance between, then part of the operation .orbit, there may be located in the center of gravity among the larger objects. .In this case, the smaller objects will be part of the period is defined as the satellite, while the rest of the time will be defined as planets. .This is not self-contradictory? .</ P> <P> </ P> </ p>.
