Hey all. While I was watching Dan's US Video I found this video about Venus colliding with Earth in three billion years. I don't know if it's true or not, but it's kinda cool.

A simulation in the future possibly Venus colliding with Earth.

Could just be the fast timestep making orbits go crazy, but if not, weird, Earth second planet from the sun... Although it didn't get much closer, so we may still live (if they don't crash)

Even if it is true, the collision between Earth and Venus is just an eventuality of one of the thousends of possible futures.......

Just because the orbits cross it doesn't mean the planets will crash together.
Like, Neptune and Pluto.

There are so large distances between planets. They could cross each other's orbits thousands of times without crashing together.

But correct me if I'm wrong. Tongue

You are wrong.

Neptun is a thousand times more mass than Pluto and Pluto cross Neptuns Orbit but not in the ecliptic.

But earth and venus and nearly same size and mass. Venus and Earth would strong interact with each other if they share orbit.

Even if Pluto's orbit crossed Neptunes, Neptune's strong gravity would lock Pluto into resonance giving making Pluto apear to approach Neptune then bump back...

Me to myself: Man I have to explain this over here, on the GravSim forum I can just talk about the resonance...

Just go here...

This is some of my resonce work stuff:
Pluto/Neptune: 2:3 res: http://www.orbitsimulator.com/cgi-bin/yabb/YaBB.pl?num=1233457261 (This is really TNO's though)
Saturninan Moons, Kiviuq/Ijiraq 1:1 res: http://www.orbitsimulator.com/cgi-bin/yabb/YaBB.pl?num=1234553664

Triton will collide Neptune. forming a new ring system in 10 million years.

I highly doubt that. Titan would have a long way to come to Neptune...

Titan is the biggest moon of Saturn...i guess you talk about Triton...

So, Titan will get launched by something, and turn on it's booster rockets, launch it self to Neptune, and come to close?

He means Triton....

Titan and Triton sound almost the same.
Btw, Triton could do a Roche Limit.

EDIT: Mars can also collide with Earth, but it can be possible to pass by it, not colliding with it!
