Let us just say I wanted to go to Jupitar and i needed to pass through the asteroid belt how do i pass it under it over i dont know

You go over it.  Many people have tried to go under it and their spaceships have exploded.

look here:\n\nhttp://neo.jpl.nasa.gov/cgi-bin/neo_ca\n\nselect what you want to see displayed from the pop-up menus and select display table.  try selecting "PHAs (Potentially Hazardous Asteroids)" from the first pop-up menu.

go all the way to the bottom and then there will say somethin like, Answers International. Hope that helps:)

Pluto..a cinch. Just go to Disneyland and wander around you are bound to find Pluto.  You an even hug him if you like!\n\nThe center of the Earth well that's hundreds, if not thousands of years in the future.  The heat and the pressure of molten iron (although at the exact center of the earth one would be in an anti gravity environment..like in outer space, because the mass of the earth is pulling on you exactly the same from all points around you).  The heat and pressure are unimaginable and it will take man many many generations to solve this problem.  We might just send a probe there..why risk a human being. Androids will like molten iron...they can relate to it..right!

Hi. This is how NASA does it : http://science.nasa.gov/headlines/y2000/ast02nov_1.htm

well the path of the planets is different for each due to the size but the are similar to a oval type shape, gravity hold the planets in orbit and as far as the asteroids they are freely moving until caught by a gravitational pull of a larger object

i suppose a planet.cause it is denser then asteroids

Yes I have.  They featured an article about it on Space.com and the NASA website.  Seems that many other Kuiper belt objects have mutiple satellites (moons) as well.  It will be interesting what the New Horizon probe will find when it gets out to Pluto and beyond.  I am hoping the launch will be on time so it can use the gravitational assist from Jupiter to get there quicker.  There was a NASA site where a person could get their name placed on a CD that is launching with the probe.  Several of my friends and I signed up and our names are on that disk now.

Rotation around an asteroid would be pretty tricky, since their mass is low. \n\nCeres would be the best place to start. It kinda has gravity. (And actually, I'd just build my base on there, and not deal with a toroidal structure). The gravity is low enough so that "blast offs" would use very little fuel, but you would still have the stability of a rock. \n\nIf you chose to build the space station in that quadrant, you'd have a firm base on Ceres. (Phobos or Demos wouldn't be bad either --- but Mars is too much of a gravity well.)\n\nThe simple fact is that you will have to assemble it in space, no matter where you fabricate the elements of the structure. Good luck, and keep me informed on your progress. I always wanted to run a pub on Ceres...

I would think that you would spiral toward Australia and then back toward us with the mid point at the center of earth's mass, each time not going as far as before .  \n\nThe reason that you would basically oscillate like that, is that the force of gravity increases the closer the centers of mass are to each other (the closer you got to the center of the earth) and so you would be accelerating the entire way till you got there and you would continue going because there would be no force acting on you to decelerate you.  As you start going away from the center toward the land down under, the force of gravity would act against your current velocity, till they cancel each other out and you start to fall toward the center of the earth this time the other way.  The reason that you would not quite make it out the other side of the hole is wind resistance and other very small forces would be affecting you. \n\nAssuming I'm right, you would eventually end up rotating in 3-dimensions around your stomach (or where ever your center of mass is) at the center of the earth.

There are lots of meteor shower Web sites out there, but the very best Web site for getting your directions straight and seeing some awesome satellites (including the International Space Station quite often) is called Heavens Above.  Just plug in any location for any time and it will give you superb constellation, planet and satellite path maps.  Note: If you print out the maps, be sure to hold them above you because the printout is aligned so that you hold it above you as you're looking up at the stars at the same time.  Superb data presented in a simple and fun format.

The Canadian Space agency web site should be your best bet.  Here is the link to the Canadarm 2 web page, with many linked pages that can be accessed.

ASTEROID FLYBY: During the early morning hours of Monday, July 3rd, asteroid 2004 XP14 will fly past Earth barely farther away than the Moon. XP14 is large enough (600 meters wide) and bright enough (11th magnitude) to see through backyard telescopes as it races across the star-fields of the Milky Way. There's no danger of a collision, just a nice photo-op for amateur astronomers.
