Just for fun, I think I'll try to figure out a delta-vee for Apophis that will make it hit Earth.

Well, that's a good question.
Nope , sorry there is no scheduled arrival in 2035, it could still happen but you're close 2036 and 2037 are much more interesting years. There is a near miss scheduled in April of 2036 and again in April of 2037, from an object called Apophis (after the bad-guy from Stargate SG1).
The reasons they repeat is because they are in close orbit to the earth so every so often the path of the Earth and these objects meet up, There are hundreds of such objects that we are aware of and probably hundreds more of which we are not.
The Apophis encounter of April 2036, will be a VERY close miss though, the asteroid will probably be able to be seen by just looking up into the night sky the day it passes, it will be closer to the Earth than many of our satelites.
The links below give better information than I can here.
You see ... actually, meteors hit the planet EVERY day. Most of the meteors are very small, (the size of grains of sand and dust). Bigger meteors also hit the Earth but the larger the meteor is the less likely you will find it in the area around the Earth.
Bigger meteors and other space junk near the Earth are being tracked by NASA and other organizations , these are called appropriately enough, Near Earth Objects. Basically started in the 1990's these programs have found dozens/hundreds of meteors / asteroids that could strike the Earth. So far nobody has found an asteroid or meteor that for sure WILL hit the Earth.
The list of all the things we KNOW about is at the link below. It's always possible there is a rock out there with our name on it , that we haven't found - yet.

You can think of it like this..by saying what are the odds of being bitten by a bug. On average, it doesn't happen very often, but if you go to a picnic or a park in summertime it could happen several times in one day - you may not even notice.
Over a long period of time (years or decades) it's not IF you are going to get stung by a bee or a bug, but how many times that's going to happen.
It's the same thing with meteors , on average a big meteor hits the Earth once every 100 to 200 years. The last time was in 1908 in Tungusta, Russia/Siberia. The comet/meteor broke up before it hit the surface of the Earth but the blast wave snapped trees for hundreds of miles in most directions.
Nobody knows if anyone died because it occured in the middle of a big frozen tundra/swamp.
Overall the risk of impacts is more or less constant but is slightly decreasing over billions of years - someone once compared it to "Living on a shooting range....Eventually, your gonna get shot."
It doesn't as frequently as it used to because the Earth and other planets have "cleared" a path through space long ago. Think of the planets like small vaccum cleaners going around the sun in circles - vaccuming their path over and over again. It takes a long time but they eventually clear most of the areas in the room that they travel near.

I hope not! LOL, i have no idea. Better get the emergency kits ready just in case! That was a joke, and a really bad one at that. But it might burn up in the atmosphere and only be the size of a pebble by the time it's anywhere near. Meteors aren't automatically planet-threatening.

I just saw this last night on discovery. It's supposed to be a near miss, but they are not sure what effect the earth's gravitational pull will have on it... so it's possible, but not likely.

I think it's on the 13th 2029. but don't worry, until then, our technologies are advanced enough to move it out of the way.

i think you're thinking of halley's comet?
or its possible, since scientists use physics to predict the movement of space objects
and meteors to happen every few million years, and this may be it
but its highly improbable
