All planets lie in the plane of their orbit, but most spin on an that is nearly (many have tilted axes of spin) perpendicular to that plane. The one exception is the planet Uranus which has its axis of spin lying very close to its orbital plane.
There is no dwarf planet named Churon. Charon is a real object, though. it is not a dwarf planet, however: it is the largest moon of the dwarf planet Pluto, which has an elliptical orbit that lies mostly beyond the orbit of Neptune.
Uranus is often referred to as the "planet that lies on its back" because its axis of rotation is tilted nearly perpendicular to the plane of its orbit, causing it to rotate on its side. This unique orientation gives Uranus its distinct appearance and unusual behavior compared to most other planets in our solar system.
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.
The orbit of each planet is completely in a plane. That is, the whole orbit would lie on a sheet of paper if you had one big enough ... there are no lumps or bumps in the orbit that rise out of the paper or droop below it.It's important to understand, though, that the orbits of all the planets don't all lie in the same plane. They're all close, but they're all different.The plane of the earth's orbit is what we call the "Ecliptic Plane". The line where the ecliptic plane intersects the "bowl" of the sky is the circular path through the stars that the sun appears to travel in the course of a year.Compared to the ecliptic plane, the plane of Mercury's orbit is tilted about 7 degrees, Mars' orbit about 1.9 degrees, Saturn's orbit about 2.5 degrees, and our moon's orbit about 5.5 degrees. This is why the sun, moon, and planets all appear to move through the same narrow band in the sky, though not exactly along the same line.People have noticed this for thousands of years, and concluded that there must be something special about this narrow band in the sky. They ascribed special characteristics and influences to that strip, and to the stars and constellations in it. That series of constellations are the familiar 12 of the band called the 'Zodiac'.
The equator is an imaginary line drawn around the Earth parallel to the equatorial plane. The orbit refers to the curved path that an object takes around another object, such as a planet orbiting the sun. So, the equator and an orbit are different concepts related to the Earth's rotation and celestial movements.
Uranus. It is tilted on its side by 98 degrees.
Uranus has an axial tilt of about 8 degrees, which means its axis lies almost parallel to the plane of its orbit around the Sun. This unique orientation causes extreme seasonal variations on the planet, with poles experiencing extended periods of sunlight and darkness.
Uranus has a rotational axis that is tilted so much that it lies nearly in the plane of its orbit. This unique tilt of about 98 degrees gives Uranus its distinct seasonal variations and causes it to essentially roll on its side as it orbits the Sun.
The plane with the smallest orbit is Mercury, and the planet with the largest orbit is Neptune.
The Earth.
There isn't one. They all orbit in roughly the same plane. Pluto orbits in a different plane, but that's not classed as a planet now, of course.
The planet that lies on its side is Uranus. Its axial tilt is approximately 98 degrees, causing it to appear to roll along its orbit around the sun.
Mercury and Pluto.
I assume you mean "around the Sun". That is the Earth's orbit. The plane of this orbit is called the ecliptic.
There is no dwarf planet named Churon. Charon is a real object, though. it is not a dwarf planet, however: it is the largest moon of the dwarf planet Pluto, which has an elliptical orbit that lies mostly beyond the orbit of Neptune.
Saturn is the sixth planet from the sun. Its orbit lies between the orbits of Jupiter (the fifth planet) and Uranus (the seventh).
