when it was a planet
2007-02-13 10:00:14 · update #1
pluto isn't a planet anymore but when it was, its orbit was so eccentric that it went across neptune's orbit and was the 8th planet from the sun for a while. but now it doesnt matter cuz it isnt even a planet

Because of the eccentricity of Pluto's orbit, it sometimes travels closer to the sun than the next 'farthest' planet out making Neptune the most distant planet from the sun.

Considering that someone mentioned about Neptune's and Pluto's orbits intercepting eachother, it won't be possible. Their orbits are inclined in such way that they do not run into eachother.
Neptune, sometimes, can be the furthest planet from the Sun. Taking that if Pluto is a planet, at some points in time, it can be the furthest away. This is because Pluto's orbit is like a squashed oval: an ellipse.
Imagine this when you draw two ovals: one round, and another squashed and long. You will see that the round oval will protude from above the diagram, and the long ellipse will have its 'tails' poking out from the round oval.
There, question answered.

No, for two reasons.
Reason 1: Pluto isn't a planet anymore. It's been demoted.
Reason 2: Originating from the Kuiper Belt instead of being a true planet, it's orbit is a lot more eccentric (flatter ellipse) than the 'official' planets. It's average distance is greater than Neptune's, but it's perihelion (closest point to the Sun) is closer than Neptune's average distance.

Pluto's highly eliptical orbit takes it inside the orbit of Neptune (relative to the Sun). The two planetary bodies do not orbit in the same plane -- Neptune is in the plane of the ecliptic, while Pluto orbits in a plane tilted from the ecliptic.
Pluto was closer to the Sun than Neptune from about 1982 until 1998 and won't be closer, again, for at least 200 years.

well, i don't even think pluto is technically a planet anymore but, no. i believe pluto travels in an eliptical orbit and it's orbit crosses neptunes orbit. so, there has to be a time when neptune is farther away than pluto.

not always ,only at its farthest point it is the most distant planet ,it revolves the sun in an elliptical orbit crossing the orbit of neptune,neptune having a more consistent circular orbit would be farthest

its not a planet we dont know if there are other planets yet to be discovered
but what yout teacher meant...
suppose sometimes one of the planets is closer to the sun say planet A is c;oser to the sun than B
later B is closer to the sun than A,
what will hapen on some day ?
A and B will collide !
this is not possible so, yes when some planet is closer to the sun than some other planet it will always be closer to the sun than the other planet.

no, because it isn't a planet at all

its orbit is eliptical, sometimes neptune is.
