EXPLORING THE KINDERKEN WORLD PLUTO'S VERY STRANGE ORBIT (Reprinted from TEDDY SPEAKS JUNE 1994) by Marshall Smith       The ninth planet, Pluto, has a very strange orbit. Unlike all the other planets which have fairly circular orbits around the sun, Pluto has an orbit that is highly oval or ellipsoid. It is so strange that its orbit moves far beyond the eighth planet, Neptune, and sometimes even moves Inside the orbit of Neptune. It currently is Inside Neptune's orbit and is now the eighth planet with Neptune being outermost or ninth planet.       One theorist has now guessed that Pluto's orbit was pulled out of shape by interaction with its nearest neighbor Neptune. The theory ls based on the assumption that all planets were formed out of a primordial cloud of gas and that originally all the orbits were regular and circular. Using a computer simulation Renu Malhotra of the Lunar and Planetary Institute In Houston, reports this possibility in the Journal Nature. She believes that Neptune's orbit began to expand shortly after the solar system was formed and thus moved into the region of Pluto and warped it's orbit.       Scott Tremaine, professor of physics and astronomy at the Unlversity of Toronto In Ontario, says, ''I'd say it looks pretty good.� But that is the kind of thing scientists say when they have no idea what the truth is but can't find anything wrong with the theory.       Another scientist, Stanton Peale of the University of California Santa Barbara. points out that Malhotra's simulation did not produce the extreme tilt (17 degrees) of Pluto's orbit compared to the rest of the planets. This also is the kind of thing scientists say when they mean the theory is �all wet'' and can't be true since it does not account for all observed facts.       Many theories have been proposed for Pluto's orbit. Some believe that is was a planetesimal captured from the multitude of space clutter far beyond the solar system. Others believe that Pluto is an escaped moon from Neptune.       A much more complete but unpublished theory is that originally Neptune was a very hot spinning ball of gas. As Neptune cooled over millions of years It shrank and as a result of the Conservation of Angular Momentum began to rotate so fast that some material was thrown out or ejected This allowed Neptune to slow down to a more stable rotation rate. But the material ejected was not thrown along the line of the ecliptic but at an angle of 17 degrees.       One result of this is that Neptune recoiled and tilted its axis of rotation and the ejected material was thrown far enough that it escaped the gravitational field of Neptune and went into orbit around the sun. No matter whether the ejected material was thrown toward the sun or away from the sun, the material would form an elliptical orbit around the sun that moves inside and outside the orbit of Neptune.       The ejected body would have been about 10 percent of the mass of Neptune and made of the same, mostly gaseous, material. Because the ejected body was so small its gravity was insufficient to hold the light gasses which escaped into the vacuum of space. What was left was a tiny rocky core that we call Pluto.       This scenario has been repeated many times in the solar system and is the primary means for the creation of most of the moons of the planets. Including the moon of Earth. (This theory will be detailed in an upcoming issue of Teddy Speaks Magazine)
