# If you had a rope long enough to tie one end on the surface of Earth, and the other on the surface of Mars. What would happen?

Update:

The rope is long enough that it won't stress or strain, and there's no sun between the Earth and Mars.

Then one can climb on that rope from Earth to Mars.

There is no material that a rope could be made of that could support it's own weight longer than a couple hundred miles, much less the distance between planets. This is the classic orbital elevator problem.

The rope would get twisted and tied up in knots because both planets are spinning.

It would start wrapping around the planets and then break.

Assuming you could overcome Earth's Gravity, the rope would burn when the Sun Passes between the Earth and Mars.  You can't say there is no sun Between the Earth and Mars, because at some point in their orbits there is.

The Robe would have to be very flexible and get longer and shorter during the orbits of the two planets and watch out for our moon.

As both Planets spin, the rope would get wound around them and become tighter

Eventually pulling themselves together

Rope would break.

The rope would break as the planets moved further apart as they go about their orbits. If the rope had enough slack to cover the greatest distance, then it would burn up in the sun as at the greatest distance earth and mars are on opposite sides of the sun. If it were a magical tether of indestructible quality magically anchored to both planets utterly immovable, then the Earth-Mars-moon system would assume a new orbit around the sun and around one another.

Earths orbital period is shorter than Mars. Get your rope tethered tomorrow and for the next 4 to 5 months, the rope would grow very slack as earth and mars close distance. Mercury is so close, it might interfere with your rope over the next couple weeks. Mars and mercury are both very early morning objects, Mars just southeast of mercury.

I would guess that they would begin to revolve around their combined centre of mass, and that this would then orbit around the sun -- with significant effects on the incidence of eclipses , our day length ,year length and seasons.

Mars would pull the rope so that Earth would move farther away from the Sun and have another glacial period.
