Ok, I do remember that most of the planets were on a plane, except for pluto (17 degrees) and mercury (6 degrees). I still do not think that Plutos and Nepture orbits directly intersect, though.

Wasn't there a recent theory that Pluto was really a distant moon of Neptune? I thought it sounded crazy.

If their orbits do not intersect, how could they?

the do intersect. look it up. but they are not flat. the declinations of teh planets orbits are different. but the orbits still cross each other. it doesent matter the orentation if they cross they cross.

also if pluto got close enough to neptune it could just jump orbit and become a moon or crash into neptune

have all the planets align? like in tomb raider?

I'm surprised no one has posted the answer:

The Question
(Submitted March 26, 1997)

Pluto's orbit crosses that of Neptune's, on what date will they eventually collide?

The Answer
Pluto "crossed" Neptune's orbit on January 21, 1979, and temporarily became the 8th planet from the sun. It will cross Neptune's orbit again on Feb. 11, 1999 to resume its place as the ninth planet from the sun for the next 228 years.


Despite the fact that Pluto and Neptune temporarily change places in their distance from the sun, they will never collide. This is due to two reasons: First, Pluto's orbit is inclined to the ecliptic. by 17 degrees. (To see an illustration of this, take a look at http://seds.lpl.arizona.edu/billa/tnp/overview.html.) So even though we say their orbits "cross", Pluto is actually quite a distance "above"Neptune. Secondly, Pluto orbits the sun twice for every three orbits of Neptune. The two planets are said to be in a "resonance orbit". For such orbits, the two bodies never get close to each other. In fact, the closest the two planets come to each other is 2 billion kilometers.

yes the did back around 1997 IIRC. well maby not all but i think 7 of them aligned then
