Can we stop a rogue planet from hitting earth?
I keep having really really scary dreams about a rogue planet hitting earth and it feels so real and i'm scared out of my mind to dream about it and i keep crying because for some reason i feel like a rogue planet will hit earth in my lifetime and i'm only 16 so my question is that if a rouge planet was on a collision course what can we do to stop it from hitting earth? also i barely know what a rogue planet is so can you tell me? and is there any known rogue planet that could come though our solar system at any point in my life time? and only serious answers please.
Will an asteriod hit and destroy earth on September 28, 2015?
--"and it sounds like if this is true" WOW. And I thought it sounded like a made-up hoax, just like all the other made-up hoaxes by these religious "end-of-the-world" prophets. It's a good thing you are an expert in these things, able to tell us that this time, it "sounds real". It is probably because you have even more years of study in astronomy than I do. --"Will an asteroid hit"? yes. Asteroids hit Earth EVERY DAY. --"...and destroy Earth on Sept. 28, 2015"? No, of course. To destroy Earth, the asteroid would have to be the size of Ceres (or maybe Vesta) and it would have been visible, naked eye, for weeks. Since I have telescopes that allow me to see even smaller asteroids, I know this one does not exist. --"secret locations" No. That was for the May 2003 end of the world (Planet X) where the hoaxer would actually rent special hiding bunkers (they made lots of money from idiots). The idea was taken up again for the Big 2012 Hoax (which was an "enhanced" version of May 2003). I thought the idea of secret hiding places was no longer linked to astronomical "ends-of-the-world", only to (yerly) upcoming World War III, which we are (it seems) very desperately trying to start. --"is it possible to stop the asteroid" No. Especially not if it were that big and that close. It might be possible to divert an Earth-killer asteroid if we had ten years notice. Fortunately, since there are no such asteroid coming our way for at least a century, I am not worried.
Can we stop an asteroid from hitting Earth?
No. Earth is hit by asteroids... many times each day. Of course, most are too small for us to worry about them. Sometimes a house is damaged (or a car), sometimes a person is injured (a kid got a broken arm a few years ago). If an asteroid is big enough for us to worry about it (like 500 feet across = 150 metres) nuking it in the last week before it hits (like in many low-quality American movies) will do absolutely nothing. If it is much bigger, then nuking it (or breaking it in pieces) might even make the problem worst (as if we would still care at that point). A giant asteroid carries lots of energy -- its mass and its speed. When it does hit Earth, all this energy is transformed into mechanical energy (digging a crater and throwing lots of material from the Earth's crust) and into heat. In this manner, if you are not killed by the impact itself, you will be fried by the heating of the crust (or by the fiery ejecta raining down on you). If we do break up the giant asteroid, the pieces still carry the same mass, going at the same speed, but most of the energy will NOT go into mechanical effect. Most of it will go into heat, making sure that we are broiled instead. The only solution would be to divert the asteroid well in advance (like years in advance) and without breaking it up (if you do break it up, then chances are good that some chunks -- which may be big -- will still hit us)
If an asteroid ever threatened Earth, how would we stop it?
The best method for destroying a huge asteroid that is headed towards Earth that I’ve come across is to explode a thermonuclear warhead a few miles above the surface. If done properly, the bomb would not break up the asteroid, but it would vaporize anything volatile on the surface (such as ice or methane). As these blew off they would provide a gentle and fairly uniform push to deflect the asteroid. It’s easier for a comet than for an asteroid.When I saw the movie Armageddon, I watched the scientists trying to figure out what to do. Then they decide to explode a bomb on the surface of the asteroid, blowing it to smithereens. NO! NO! I shouted (in my head). You’ll just turn a bullet into shotgun shrapnel, doing more damage than the single impact would have done! It turned out, of course, that I was right. The scientists should have first checked the theory, not simply made up a new idea just because it sounded good and used it without peer review.The warhead could be one (or several) from our existing fleet of intercontinental ballistic missiles. We would just have to reprogram their flight paths, and their detonation program. These weapons typically explode before they reach the surface, in order to inflict maximum damage in a war, so the modifications should not be difficult. The multiple warheads don’t need to be detonated simultaneously, since the deflections can be quite small.The problem, of course, is that we really should test such an approach before we try it. Right now that is impossible, since international treaties prohibit nuclear weapons in space. However, if an asteroid were predicted to hit the Earth, then there might be time to agree to an exception to the treaty, both to make a test (on a distant non-threatening asteroid) and to do the actual deflection. There is great value in doing the deflection early, when even 1 degree change in orbit would cause the asteroid to go miles away.
When will an asteroid hit our earth again?
We don't know, but there is no asteroid going to hit us in 2012, 2036, or any year in between. In fact, there is no known object on a collision course with Earth for at least the next 100 years. Meteorites hit the Earth daily, but there's nothing bigger coming anywhere near us. Apophis will make a close pass in 2029, but won't hit us. It has a miniscule chance of impact in 2036 (0.0004%), but you have a far bigger chance of dying from a fall in the home than Apophis has of impacting Earth, much less killing you. It's all bullsh!t.
