What orbital perturbations might we see if the mechanical stability and gravitational equalibrium of the inner Solar System were to be disrupted by, oh say, the sudden disappearance of Mars?

I've been a big fan since the beginning.

Hello, David! Mars vanishing would have very little effect on the inner solar system, and not much if any on the outer. Now if Jupiter decided to vanish, we might notice the difference... Any astrophysicists out there willing to do the math... say, a ten body problem with asteroid blips?

Hmmm...since I have been recently focused on Sunday's Perihelion Event, I have to wonder about this. Now it wouldn't cause Venus and Earth to go flying off from the orbital plane, but I have to wonder if earth's orbit wouldn't flatten a bit, become more circular.

Not that Perihelion and Aphelion have that much affect on earth's weather, as we are four million miles closer to the sun in January as we are in July.

But Jupiter suddenly vanishing, yeah, that would cause some changes PDQ...the Trojan Asteroids being the first thing that comes to mind...the shepherding affect that Jupiter has on the Asteroid Built and incoming comets.

Something that would definitely be "phun" to model on the UCSD Super Computer.

Some speculate the melting ice caps will effect plate tectonic activity. The Caps themselves damper or are in some range of equilibrium with of the tectonic plates and vibrating mantle.

the melting caps will make the ocean heavier. the forces of the currents and tides sloshing over 3/4 of the surface of the earth will vary from the last few thousand years. we could see a few more volcanoes going off, a few more earthquakes.
