Well, that would depend on how it "disappeared." If it just vanished with no trace, rather than going supernova or being knocked (somehow) by another star or black hole or something, then a planet would probably keep traveling in a relatively straight line in the direction it was moving at the moment of the disappearance. I say relatively because of course other things that were near it, or came near it during its journey would have a gravitational influence as well. If it came into the influence of another star, it might even start orbiting again (but that is a long shot).
Needless to say, we would also all die without the sun as a source of light and heat, but I'm not sure that is relevant to the discussion.
(Please note that in real life, masses can't simply "disappear".) For 8 minutes and 20 seconds (in the case of Earth), or for less or more time, depending on the distance of the planet from the Sun, the planet would continue orbiting the place where the Sun was. After that, the change in the gravitational field will have had enough time to reach Earth; the planet will no longer "feel" the pull of the Sun, and will continue moving in a straight line.
There would be no orbit. You have to have a body to orbit around and without a star or other planet to orbit around, it would just move in a straight line.
Yes. Neptune orbits the sun.
gravity... i think
If the Sun and the Sun's gravity suddenly disappeared, each of the planets would go flying off into space at their orbital velocities. In the case of Earth, that's about 67,000 miles per hour. Depending on where each planet was in its orbit, there might be the possibility for a collision or a near-miss with another planet. We humans wouldn't really notice; we'd be too busy freezing to death to care.
It is unlikely to happen, at least in my life time, which is a great comfort to me. But, as we and the other planets in our solar system orbit round the sun because of the sun's attraction, if the sun suddenly disappeared, there would be nothing to stop us being flung outwards into space.

The Sun doesn't move fast, but if you mean which planet moves fast around the sun then it would be Mercury, because it is closer.
There would be sunlight as long as we are close enough to our sun. If our planet escaped from the suns gravitational pull and disappeared off into space away from the sun then it would get very dark. This is unlikely to happen though.
The orbit would increase in size (the planet would orbit farther from the sun).
Neptune would move the slowest. The orbit speed is related to the distant the planets are to the sun. Farther the planet, slower the pace. Remember, Pluto is no longer a planet.
the sun
Without the suns pull of gravity, the Earth and any other planet would move in a straight line. It is the sun that forces the planets to move in an orbit.
The planets move in an act of gravity
No, a sun is not a planet but star.
The sun is not a planet, its a star but the hottest planet is venus but if the sun was a planet ,it would be the hottest.
