Another Earth In Our Own Solar System.

Let me first of all categorically state that I fully understand that no such planet exists in our solar system. I am fully aware that there is only one earth in our solar system.

However, let us hypothesize - say I was writing a brief science fiction novel whereby an identical planet to Earth populated with about 10 billion humans appeared in our solar system by some freak "accident" (it does not matter how, just that it happened).

Now, in what orbit/position would this Alter-Earth have to be in, in order to not negatively affect the state of our own planet (e.g. not cause devastating earthquakes, tsunamis) and not devastate the entire harmony of our solar system.

Would it have to be in the position of the so-called "Gor" Earth (i.e. "Counter-Earth")?

Cheers in advance.

There could be some sort of off phase planets in the solar system. Something that isn't really in the dimension that we know. When you consider that noone has come up with a completely accepted reason why time even exists, you come to a realization that there is much more to learn than mankind realizes.

Already been made as a pretty nice indie movie.... look up "Another Earth".

2nd

MARS

At one time before we looked out.

Also lending to the distinct possibility that we DO have neighbors close
by: but just with a different 'paint job'. They just have access to that slit
in the sheet that we haven't found yet: but afterwards it could be a short hop.

My deal is the "constant" of finite knowledge being totally fluid discredits the
scientits who lately have become quite inflexible to speculation-- until you get
the arguments dealing in something super small.

In the short term, yes, that would be suitable place for it.
In the long term, its an unstable situation.

Some people actually believe that, only the planets are overlapping each other. 3d and 4d.

The earth depending on what vibration l;evel you are on is in a different reality...
or something like that.

Another Earth could possibly orbit our Sun's hypothetical binary companion that is, as yet, undiscovered.

Excellent movie. Here's the trailer:

I hate it when that happens. I once started to write a book and got about 2 chapters through it before I realized it was just a "V" rip off, unintentional, but someone already thought of it...*grumble*

Meh, Everything is derivative of something.

To quote South Park "Simpsons did it"

The key is not to worry if what your doing is a rip off or not, just do your thing and make it your own.

there's no need for science fiction...gliese 581 star system got multiple planets which may harbor life

still i dont thin k i know what is the purpose of this thread



and the title is misleading...i came here with the intention of bashing the op for some false youtube video...no fun for me damn ><

I was extremely let down by that movie.

Mars could be a dead Earth. If one of the Rovers can possibly find some fossils there, it would prove it. Water is one thing, but fossils leave no doubt whatsoever. ~$heopleNation

Interestingly enough, I've played with this using Universe Sandbox.

You could have another earth sized/massed planet halfway between Earth and Mars, and things stay quite stable for a very, very long time.

Same goes if you place it halfway between Earth and Venus.

There are some effects, but they are very slight, in other words no planets being thrown out of the solar system or into the sun.

For the "Gor Earth" idea, the only way for it to be stable is for the 2nd earth to have the exact same inclination and ecentricity as our Earth (our orbit is not a perfect circle around the sun).

in earths orbit exactly 180 degree opposite - would have negligable imact on this earth or other planets

I thought this initially but wanted to run the math as to how it would play in the solar system. Likely best candidate to fit our current mathematical models, but still would need to be factored in.

I see three options, off the top of my head.

1) orbiting perpendicular to the plane of the ecliptic


2) in orbit around Jupiter (or another Gas Giant)


3) Venus (see below)




km radius ------ Body

695,000 Sol

71,492 Jupiter
60,268 Saturn
25,559 Uranus
24,764 Neptune

6,372 Terra
6,051 Venus
5,321 Vesta
3,397 Mars
2,631 Ganymede
2,575 Titan
2,440 Mercury
2,410 Callisto
1,821 Io
1,738 Luna
1,560 Europa
1,360 Orcus
1,353 Triton
1,200 Eris
1,153 Pluto


Notice that Venus practically is Earth already.
