Based on Newtonian Laws of Motion, asteroids are still under the original velocity imparted to them when they were made. The only external influences are the gravitational pull of the sun and other celestial objects.
Most meteorites come from asteroids, which are rocky bodies orbiting the sun. Some meteorites could also come from comets, which are icy bodies. Both asteroids and comets can collide with Earth, resulting in meteorites.
As far as we know, no rogue planet has ever come near Earth. Comets and asteroids have come near Earth, but not actual planets.
Asteroids, even very large ones, actually come close to earth regularly and cause no harm and no effect on life on earth. The concern would be a large asteroid crashing into the earth.
Main Belt asteroids -- a band of asteroids located in the "missing planet" gap between Mars and Jupiter. None of these are economically attractive in a near term program because they are too far from Earth.Amor asteroids -- asteroids whose orbits approach but do not cross Earth orbit, and whose orbits are further from the Sun than Earth's orbit (i.e., "outside-t" Earth orbit). Many have orbits which reside entirely between Earth and Mars. Some of these are economically attractive in the near term.Apollo asteroids -- asteroids whose orbits cross Earth's orbit. Apollo asteroids spend most of their time outside Earth orbit. Many of these are economically attractive in the near term.Aten asteroids -- asteroids whose orbits cross Earth's orbit. Unlike Apollos, Atens spend most of their time inside Earth orbit. A large percentage of known Atens are economically attractive in the near term.
Apollo asteroids are a group of near-Earth asteroids with orbits that intersect with Earth's orbit. They are named after the first asteroid of this group discovered, 1862 Apollo. Some Apollo asteroids are classified as potentially hazardous asteroids due to their close approach to Earth.
They can.
Yes
Yes. Asteroids can enter earth's atmosphere. In such an event the asteroid will probably strike earth's surface.

Comets come toward earth during their orbits. They are drawn toward the sun by gravity and sometimes cross earth's orbital path in the process.

In dicussing asteroids, NEO stands for Near-Earth Object. NEOs are asteroids whose orbits come close to or cross Earth's. This creates a potential hazard for a collision.
Asteroids that occasionally cross the orbit of Earth are known as Near Earth Asteroids. Asteroids that both cross the orbit of the Earth and are large enough to pose a significant threat in the event of an impact are known as Potentially Hazardous Asteroids.
Asteroids are rocky objects that orbit the Sun, and sometimes they can come close to Earth. When an asteroid collides with Earth, it can cause a big explosion, like a giant firework. This explosion can create a lot of heat and dust, which can block out sunlight and affect the Earth's climate. Scientists study asteroids to understand their movements and protect Earth from potential impacts.
