Venus Mars and Mercury

[Lina houti]

Hello my name's Lina Houti and I want to talk about three planets which are similar to the earth(venus, mars and mercury) ,intern planets because of their closed distance to the earth.Their characteristics make them different from the five other extern planets( Jupiter, Saturn, Uranus, Neptune and pluto

Hello,

Pluto is no longer considered a planet according to the International Astronomical Union, instead its a dwarf planet.

Also I'm not sure if I ever heard of the term "intern planets". I've heard of them being declared the "inner planets", or "terrestrial planets", due to being the "inner" planets and the planets that have a rocky surface, rather than the gas giants that are out beyond Mars.

Speaking about Mars and Venus - for a long time now i keep wondering if it would be possible to have some sort of stable orbital resonance, if both planets orbited significantly closer to Earth's orbit? Closer to the center of Sun's Goldilocks Zone - enough for both to remain habitable. Now that would be a configuration everybody would want to explore

A triangle, the Lagrange points?

But better have six Earthes as a hexagon, then they will be placed in the Lagrange points of each other.

Unfortunately Venus and Mars are too massive to remain stable at Sun - Earth Lagrange Points. That's why I'm thinking more about separate-but-close orbits in a resonance - so that all three planets wouldn't perturb each other dangerously. Mars especially would be in danger of being knocked out of his orbit.
