Meteorite is the part of meteor which reaches the earth's surface.

Halley's comet is named after the scientist Halley who saw it first time.

Occurance of comets is a natural phenomenon and there is nothing superstitious about it. Many comets appear after fixed time interval for example, Halley"s comet which appears once in every 76 years.

Meteors are small objects that sometimes enter the Earth"s atmosphere. However, due to the high speed of the meteor friction is created between its surface and Earth"s atmosphere causing it to heat up. Thus it glows and evaporates quickly and appears for a very short period of time as a bright streak of light.

Comets revolve around the Sun in a highly elliptical orbit such that at one end of the orbit it is very far from the Sun and at the other end it is near to the Sun.

A comet generally appears as a bright head with a long tail.

Meteorites are useful mainly because they help the scientists in studying the material from which the solar system was formed.

Some meteors are large enough to reach the Earth's surface before they evaporate completely. Such meteors that reach the surface of Earth are called meteorites.

Asteroids are rock-like structures that occupy the huge gap between the orbits of Mars and Jupiter. 

Meteors that are small in size evaporate before they can reach the surface of Earth due to the heat generated because of friction between the meteor's surface and Earth's atmosphere. Only the bigger ones reach the surface of the Earth.

Despite its name, shooting stars are not actually stars. Shooting star is either a piece of a small rock or dust from space that heats up when is enters the Earth's atmosphere. Shooting stars are basically meteors.

Both asteroids and meteors are part of solar system.

In the outer Solar System, comets remain frozen and are extremely difficult or impossible to detect from Earth due to their small size. As a comet approaches the inner Solar System, solar radiation causes the volatile materials within the comet to vaporize and stream out of the nucleus, carrying dust away with them. The streams of dust and gas thus released form a huge, extremely tenuous atmosphere around the comet called coma, and sun's radiation pressure and solar wind cause the tail to point away from the Sun.

Orbital period of Halley's comet is $76$ years.

The tail of comets so formed, When comets come closer to the sun, because the sun's heat vaporizes some of the comets' material, releasing dust particles that were trapped in the ice.

The first and largest, Ceres, was discovered Jan. 1, 1801, by the Italian astronomer Father Piazzi (1746–1826).

The streams of dust and gas thus released from a huge extremely tenous atmosphere around the comet called coma and force exerted on coma by the sun's radiation pressure and solar wind cause an anormous tail form which points away from the sun

Meteors seldom reach earth because of vapourization caused when they pass the atmosphere.

In addition to celestial objects like $\textit{Comets}$, we also have  $\textit{Asteroids}$ which are small rocky bodies orbiting the sun and mostly found in the belt (region) between Mars and Jupiter. While there are also other asteroids lying beyond this region whose paths often come in close proximity with orbit of earth. \par Many a times collision between two asteroids, can result in small pieces breaking off from the bodies. These pieces are called $\textit{meteoroids}$. If a meteoroid enters the earth's atmosphere, it vaporizes and turns into a $\textit{meteor}$.

In solar system, the Oort cloud is the farthest from the sun.

Pluto has a highly tilted orbit, about $17^0$. This strange orbit gives Pluto some unusual characteristics, sometimes bringing it within the orbit of Neptune.

Answer is A.

The planet Pluto and objects beyond it are called Plutons and they are the new members of the solar system. The order of the Plutons is Pluto, Charon and 2003 UB.
Plutons have highly tilted orbits and take more than 200 years to revolve the sun.
Hence, the statement is true.

Shooting stars look like stars that quickly shoot across the sky, but they are not stars. A shooting star is really a small piece of rock or dust that hits Earth's atmosphere from space. It moves so fast that it heats up and glows as it moves through the atmosphere. Shooting stars are actually what astronomers call meteors. Most meteors burn up in the atmosphere before they reach the ground. However, once in a while a meteor is large enough than some of it survives and reaches Earth's surface. Then it is called a meteorite.
Hence, shooting star is a common name for the visible path of a meteoroid as it enters the atmosphere, becoming a meteor.

Comets are cosmic snowballs of frozen gases, rock and dust when passing close to the Sun, heats up and begins to outgas, displaying a tail. Comets have a wide range of orbital periods, ranging from several years to several millions of years. An example is the famous Halley's comet which has an orbital period of 76 years.

 A meteorite is a solid piece of debris from such sources as asteroids or comets, that originates in outer space and survives its impact with the Earth's surface. It is called a meteoroid before its impact.

A shooting star is another name of a meteroid that burns up as it passes through earths atmoshpere.
