    I dont know this is my correct posting thread.
    What happen if Venus hit large Asteroid as size that wipe out Dinosaur or size of Moon?
    1. Its that possible to cool down very thick atmosphere of Venus and triger to Ice Age.?
    2. Its their any possible Venus hit asteroid on future?

    Those are two very different questions. I think that if Venus hit an asteroid the size that wiped out the dinosaurs, there would be very little effect.

    If Venus hit an object the size of the moon, the effects would be enormous. I'm certain the surface of the planet would melt.
    As above, so below

    Or melt more. If Venus did cool down from such an impact, it would likely be millions of years before it was appreciable; in the shorter term it would be much warmer.

    starwars,

    Welcome to BAUT on your very first posting.

    If the asteroid were big enough it could blast off much of the atmosphere of the planet and probably create huge clouds of dust blocking the sun and an eventual ring or even moon around the planet. It would be best if the collision happened on opposite side to us to keep much of the debris moving toward the sun rather than toward us. It might work out well if the asteroid contained a lot of water/ ice. The planet might cool off quickly, gain rotational momentum, form lakes or oceans possibly making it a future habitat for Earth life of one kind or another but probably not a future vacation spot like Hawaii

    Venus getting hit by an object the size of our moon probably would be bad news for us regardless of where it was.
    First you have to ask where an object of that size came for. Then even if it was hit on the other side of the sun we'd soon see ourselves in the debris field. If we got minimal adverse effects from the impact we'd still not see Venus as any more hospitable for millions of years. It would be interesting to confirm models of such an event.

    What would happen is like asking how long is a piece of string. Then answers are almost infinite. What is the object made out of? What is the angle of impact? What is the speed of the object? what direction was it heading?
