No two of them are exactly in the same plane, but they're close.
The one that's inclined the most with respect to all the others is, as you might guess, Pluto.

Here are the inclinations of the planetary orbits, with respect to the plane of Earth's orbit:

Mercury . . . 7.0 degrees
Venus. . . . . 3.4
Mars. . . . . . 1.9
Jupiter . . . . 1.3

Saturn . . . . 2.5
Uranus. . . . 0.8
Neptune. . . 1.8

Pluto . . . . . 17.2 degrees

What will happen if the planets do not follow their orbits?

If a planet doesn't follow its orbital path, then it may crash into other planets, moons and/or other object floating around in space.


What two planets have a unique rotations?

Venus rotates in the opposite direction to most other planets, a phenomenon known as retrograde rotation. Uranus rotates on its side, with its axis almost parallel to its orbital plane, causing extreme seasonal variations.


Which planet's orbital shape would be most similar to Jupiter's orbital shape?

Neptune's orbital shape would be most similar to Jupiter's orbital shape in terms of being both slightly eccentric and inclined relative to other planets in the solar system. Both planets have oval-shaped orbits that are not perfectly circular, and they have orbital inclinations that are not in the same plane as the rest of the planets.


Is neptune the only planet that rotates on an axis parallel to its orbit?

The question doesn't make much sense. I think it probably should say: "an axis parallel to its orbit plane". In that case, the answer is that Uranus (not Neptune) is the only planet that rotates on an axis parallel (roughly) to its orbit plane.


How do the planets and ''dwarf planets'' differ?

Its mainly due to their size, and the fact that Dwarf Planets have not cleared their orbit of enough of the other rocks and planetoids that are also at that orbit. Pluto has not cleared its orbit of enough matter to be deemed a major planet, while all of the remaining 8 planets have.

Which outer planets rotate on their sides?

Uranus is the only outer planet (and only planet in our solar system) that rotates on its side.


Which planet is not in the orbital plane?

Pluto is considered a dwarf planet and its orbit is more inclined compared to the eight traditional planets in our solar system. This means that Pluto does not lie in the same orbital plane as the other planets.

How does a planets orbital radius affect its orbital period?

A planet's orbital radius directly affects its orbital period through Kepler's third law of planetary motion. The farther a planet is from the star it orbits, the longer its orbital period will be, assuming all other factors remain constant. This relationship is expressed mathematically as T^2 ∝ r^3, where T is the orbital period and r is the orbital radius.


Will earth crash in to any other planets?

No. As of current known orbital data, the Earth will never be in a position to collide with another planet.


Which planet moves the most slowly in its orbit?

Of the major planets, Neptune. The speed of planets in their orbits is directly related to their distance from the sun. The farther a planet is from the Sun, the slower its orbital speed.


Why do planets orbit the sun longer than other planets do?

Planets that are farther from the sun have longer orbital periods due to the influence of gravity. The gravitational force between the sun and a planet decreases with distance, so planets farther out experience weaker gravitational pulls, resulting in slower orbital speeds. This explains why outer planets like Neptune have longer orbital periods compared to inner planets like Mercury.


Small changes in the orbits of planets caused by the gravitational pull of the other planets in the solar system are called?

Perturbations. These small changes can cause slight variations in a planet's orbital path due to the gravitational influences of other planets.


Why does mars orbits faster than than the other planet?

This is false. Mercury is the "fastest" planet, with Venus and Earth next. IN fact, the orbital speed of any planet is inversely related to the distance from the Sun; close-in planets orbit faster than farther-out planets.
