as we all know, the eight planets of the solar system, and all the other celestial bodies revolve around the sun, they have their own respective orbit each other noninterference, running smoothly in the solar system.Today, we would like to say Pluto in recent years.
in the past two years, due to the progress of science and technology, we can know about Pluto is more and more detailed.Especially in the United States "new item" detector after 10 years of flight finally reach Pluto orbit, especially for human Pluto provides one eye.
the scientists found that using scientific computing in Pluto is equivalent to the earth more than 90000 days a year, also is equal to 246.Because Pluto is one of the most on the edge of the bodies in the solar system, so it's orbit plane is also the biggest, relative to its revolution time will be longer.
in each period of revolution is different.This is because each object are different distances from the sun, is not the same as the journey around the sun, so that caused the objects and far orbital period.
as we all know, the earth's orbital period is 1 year, and the shortest mercury orbit orbital period for 81 days, the period of revolution of Mars is about 1.9 years, almost two years.And as far as Neptune 165 years to turn a circle around the sun.However, compared with Pluto orbital period is longer than mercury's orbital period, 3 times longer than Neptune in 80.Similarly, stay on the Pluto a year on earth for 246 years.
ancient Chinese used to say, people will go to the underworld, especially in the sky of Pluto, so, Pluto is often the ancients regarded as people walk.
the scientists also found that Pluto and Mars, as has the crack surface of the earth.And the crack surface is with Pluto poured out of the core movement nitrogen ice causes the effect of the flow.The discovery of Pluto internal core provides new evidence in the sports.
however, Pluto will always is an important part of the solar system, our inquiry for Pluto will also with the improvement of science and technology, more and more deeply.Perhaps in the near future, human detector on Pluto time just a few short years, relative human distance Pluto also will be more and more short.
