in daigrams of our solar system all 8/9 planets are shown in the same plain is this so?

Answer 1

No. All the planets do not have the same plane of revolution.

One of the main arguments against pluto being considered a plane of the solar system is the great difference in the "tilt" of its orbit with respect to the rest of the planets.

The inner-planets namely Mercury, Venus, Earth and Mars also have a slight but significant tilt in their orbits.

You could look up this link for a graphic display of the orbits:

Answer 2

No.This is only shown to elementary level students because of their lesser age.

Actually all planets do not revolve around the sun in an orbit all of which can be shown in a plane piece of paper.

For instance the now called "small planet" or "planetiod" has a rather complicated orbit around the sun.

Pluto's 248-year orbit is off-center in relation to the sun, which causes the planet to cross the orbital path of Neptune. From 1979 until early 1999, Pluto had been the eighth planet from the sun. Then, on February 11, 1999, it crossed Neptune's path and once again became the solar system's most distant planet. It will remain the ninth planet for 228 years.

Pluto's orbit is inclined, or tilted, 17.1 degrees from the ecliptic -- the plane that Earth orbits in

In The case of mercury also, the orbit is inclined at an angle of 7 degrees from the ecliptic.

The newly discovered planets like sedna also have highly eccentric, inclined orbits.

Therefore it is wrong that all planets have orbits that can be shown in a plane.

Answer 3

Actually they are very close to a linear plane which is why it is shown this way. Though Pluto is actaully on a slight slant as opposed to the other planets. Recently ;however, Pluto has been taken out of the planet designation so take that as you will. Try NASA's website www.nasa.gov for more info, or even some of the arcives from yahoo will help.

Answer 4

All the planets travel about what we call the ecliptic plane. Though varying between them none travel in the same identical plane. Pluto was so varied that at times its orbit brought it closer to the sun than Neptune, making Neptun the farthest planet away from the sun.

Answer 5

It is reasonably accurate. The extent of the solar sustem is so large , that compared to its size the solar system is v v thin. The plane defined by the earth's orbit around the sun ( the eclptic) is to a good approximation the plane of the solar system.More precisely , solar system is a very thin disk.

Answer 6

The plane of the ecliptic is different for each planet, but only by relatively few degrees. It is therefore easier to show them as co-planar, especially in those old models (orreries?), even if not strictly true.
Similarly , the moon does not orbit exactly over the equator, it does wander north and south during the year.

Answer 7

All (remaining) planets revolve around the sun in the same plane (called ecliptic). Pluto's orbit is in a different plane. That is one of the reasons it's been "demoted" and is no longer considered a planet.

Answer 8

Im taking a guess that if this is so.It is because the sun is spinning like all the other planets.It too must have a bulge in its equator with more mass.Thus creating more gravity at this plane,keeping the planets in a relative plane to the suns equator.
Just guessing.

Answer 9

The word you want is plane not plain. They are pronounced the same as each other, of course.

It makes for simpler diagrams to show them this way, though of course Pluto's orbit is somewhat tilted and not co-planar with the other planets,

Answer 10

No. All planets have a slightly different orbit. For instance Pluto has a elliptical orbit and is sometimes closer to the Sun than it is to Neptune which is it's neighbouring planet
