What would happen if Venus were moved and dropped into Earth's orbit?

Question

I know that another planet sharing Earth's orbit would eventually put both objects into unstable orbits, possibly in a matter of mere years.

But I'm interested in a specific scenario, if Venus were placed in Earth's exact orbit, on the opposite side of the sun, but moving at a higher velocity (in effect “catching up” to Earth) then;

A) At what distance would adverse effects (major and minor) be felt on the two planets?

B) What would these specific effects be?

C) At what stage would the Earth become really unliveable?

Thanks in advance.

Answer 1

DISTANCE DICTATING DISASTER:

Once Venus and Earth entered into one another's tidal tug, with the Moon's orbit destabilized, the tidal force would accelerate They would fall into one another at a geometrically increasing rate due to the decreasing distance between them.

SPECIFIC EFFECTS:

The Moon, with a possibly destabilized rotation, would probably, by my guess, plummet into one planet or the other. But there seems a chance that it might continue in orbit around both unless it was caught smack in between during the collision.

The tidal forces would lead to huge tidal waves, tsunamis, hurricanes, and as they approached, there would begin a rapidly accelerating confluence of the two atmospheres of the two planets, at first running together in a thin stream, starting as an unbelievably high tide and ending up with a blending of the atmospheres. First a thin stream of air from each, then a wider stream, would reach up like identical fingers then join like hands, then thicken into a river of atmosphere exchanges, transferring from Venus acid clouds and a dense, hot, poisonous atmosphere to blend with earth's.
:
This evil joining of incompatible atmospheres and the attendant air turbulences would kill us quickly enough, so that it would be lifeless planets that finally crashed.

The " twin planet from Hell" would have made a suicide attack, battered and strangled her fleeing sister at the cost of her own life. All the features of the Moon, Venus and Earth would be erased as they became one large, lifeless planet still remaining in a stable orbit around the sun.

The moon, if half-buried in the molten mass, might protrude from it on one side like a bizarre growth, because, while all but a thin surface of the twin planets is molten, the moon, according to recent studies, is solid nearly to the core.

Answer 2

well, it depends, really. It can be opposit Earth or beside it when circling the orbit.

a. either Earth or Venus will be a caonsdered a sattelite of either.
b. either temperature will affect either planet.
c. If you're still talking about those planets in one orbit, then its obvious. Venus goes left, and Earth goes left, so one time they will collide...

Answer 3

Venus will be digested by the earth in time.
