A comet's tail points away from the sun. Sometimes the dust and gas separate, though, because they are driven by two different effects, radiation pressure and solar wind, respectively. Both point mostly away from the sun, but not always exactly. Photographs of Comet Hale-Bopp show this effect well, for example, the Astronomy Picture of the Day at the link shown. A comet in deepest cold space is generally thought of as a giant dirty snowball with the snow made of water ice, and frozen organic liquids, and the dirt of small rocks and dust which are the debris of explosions and collisions of different bodies in space. It is only when the comet approaches the sun and warms up that surface ice melts and vapourises carrying dust with it and forming a large cloud that we can see clearly. It is at this stage when the effects mentioned above act on the cloud and sweep it behind the comet relative to the sun to form a tail or tails, and because there is no atmospheric air in space the tail always points away from the sun even when the comet is travelling away from it.
Seasons are caused buy the tilt of the Earth's axis, and the rotation of the Earth around the Sun. There's only one hemisphere at a time that can point towards the sun. The one that's pointing towards gets summer and the one that's pointing away gets winter.
Currently, the Earth's south pole is pointing towards the constellation of Octans. This constellation is not very well-known, but it is used for celestial navigation as it helps determine the location of the south celestial pole.
It is quite common for small meteors to hit the Earth. Larger impacts by an asteroid or comet are also possible but happen much less often.
Sometimes they do; that's what a "meteor shower" is. The point is that all of the rocks and dust given off by a comet, and the head of the comet too, travel the way gravity and the light pressure of the Sun force them to. The head of the comet is freely falling towards the Sun. (if a comet gets close enough to a planet, the gravity of the planet becomes significant, and sometimes the comet will collide with the planet; look at Shoemaker-Levy 9, which hit Jupiter in 1994.) As the heat of the Sun begins to melt the ices of the comet, gas and dust escape from the comet. Because the gas molecules and dust particles are very light, the pressure of the Sun's light pushes them away from the comet; this forms the "tail" of the comet. Over the course of thousands of orbits, the gas and dust spreads out to fill in much of the orbit of the comet. Where the Earth's orbit intersects the comet's orbit, we see annual meteor showers.
Halley's comet is not predicted to hit Earth in the foreseeable future. The next time it will be visible from Earth is in 2061.
Theoretically it is possible, but the odds are realy against it.
The sun might explode some huge comet might it the earth
A compass needle aligns itself with Earth's magnetic field, which causes it to point towards the Earth's magnetic poles. The needle behaves like a tiny magnet, with one end pointing towards the magnetic North Pole and the other end pointing towards the magnetic South Pole.
Comets, while visible in the sky, do not normally fall to Earth. Meteors do fall towards Earth very quickly.
The sun is the largest out of the three and then the earth and then a comet.
Assuming the comet is far away in the outer solar system, it would take light approximately 8 minutes to reach Earth from the Sun, and then more time to reach the comet depending on its distance. Traveling at the speed of light, it would take a few minutes to several hours or more to get from Earth to a comet, depending on its specific location in space.

No; creating zero gravity on Earth is not possible, unless the lab is at the center of the Planet or is free falling; like an aircraft accelerating towards the ground, namely the Vomit Comet. Stephen Hawking took that ride!

The name of the comet that will pass Earth on August 15, 2011, is the comet Honda.
