It's possible. Neptune can be struck by any of these space objects just like earth or any other planet can, if the orbital conditions allow them to come into contact. As regards any of these space objects changing the orbit of Neptune by passing close by, the mass of Neptune is too great to have its orbit significatly affected by any of these "small" objects.
Yes but they would have to be above a certain size so as not to burn up high in our atmosphere. You shouldn't worry though because NASA is tracking and monitoring all objects above this size threshold, and have plans in place should one pose a significant risk, such as blowing it to pieces with a nuclear missile. So you shouldn't worry about us becoming extinct thanks to a meteor strike, like the dinosaurs.
We have no information about how often meteors strike the planet Neptune. It is almost certain that it happens, but Neptune is so far away that it would have to be an enormous asteroid striking the planet to be visible on earth, unless the Hubble happened to be looking at Neptune anyway.
First of all, Neptune is a gas planet so it would go right through. Second of all, only German IV Panzers have the ability to hit Neptune.
No, Neptune is the eighth planet in the solar system.
Well, if you look at them.
they can but it rarely happen
Comets are named after the people who have discovered it or by the shape or after break away from a parent comet. eg: Halley's comet Tempel-Tuffle comet Biela's comet Encke's comet Ikeya Seki comet kooutek comet comet west comet Bowell comet IRAS -Araki-Alcock Comet Austin.

A comet head is the top of the comet like its nucleus is on the top of the comet.
Halley's Comet never comes to Earth. The comet - as with all astronomical bodies - follows its own orbit, falling endlessly through the solar system. Halley's Comet is currently a little further from the Sun than the orbit of Neptune, moving very slowly outward from the Sun. It will linger there, reaching the peak of its orbit in about 15 years, before beginning its long slow fall back into the inner solar system.
A comet is a space thing that has a heavenly body and a tail. The most famous comet known is Hailey's comet.
Halley's Comet is currently a little beyond the orbit of Neptune.
Halley's Comet is following its long orbital path. It is currently a little past the orbit of Neptune, and is not visible.
it travels three times as fast as a comet
A comet can approach Pluto the closest, as can Neptune.
No. Haley's Comet never gets properly out of the solar system, while the Oort Cloud is far outside the orbit of Neptune.
No. Halley's Comet barely gets past the orbit of Neptune, and not by much. It is well short of reaching into the Kuiper Belt.
Pluto is a dwarf planet. It could be an asteroid, or it could be a moon that escaped the orbit of Neptune. It could Not be a comet. Comets are chunks of frozen ice that travel in orbit around the sun, and as they near the sun, parts of the comet melt and leave a trail of melted water in their wake. Pluto never gets near the sun to melt. Pluto never gets nearer the sun than the orbit of Neptune.
Halley's Comet is PART OF our solar system. Halley's Comet is the best-known of the short-period comets, returning to the inner solar system every 76 years or so. It never gets much further away than the orbit of Neptune.
Right now, on March 20, 2011? There is none. The frozen core of Halley's Comet is drifting away from the Sun, and is out past the orbit of Neptune and slowing down. In about 10 years, Halley's Comet will reach aphelion (the farthest point in its orbit) and slowly begin to fall back inward. The comet probably won't develop any kind of tail until it gets in about to the orbit of Jupiter; that will be around 2055 or so.
No force is necessary to keep a moving object in motion. But if you want it tofollow a curve, such as for example a closed orbit, then that takes force. Theforce that keeps Neptune in its closed orbit is the same force that keeps everyplanet, moon, comet, and asteroid in its own closed orbit around its own centralbody. It's the force of gravity.
a comet/meteorite
Nothing much, recently. Halley's Comet is out beyond the orbit of Neptune. moving slowly through space near the peak of its path through the solar system. Because it is so far from the Sun, it is frozen solid, with not gaseous coma reflecting the sunlight. And because comet nuclei are fairly small, it is invisible in all except the largest telescopes.
