What is the tail of a comet made of

A comet usually has two tails, though only one - the vapor trail - is commonly seen from earth (the other is a gas trail). It is made of vapor blown off from the comet by the solar wind - it is mostly water vapor, but contains many other molecular substances, too - ammonia, cyanide, methane, etc.

elliptical

Which planet do most known extrasolar planets most resemble

Jupiter Neptune

The planet that most extrasolar planets resembles Jupiter.

Jupiter(apex)
Most of the confirmed Exoplanets are larger gaseous planets with large masses. These are easier to detect and confirm due to their size. They most resemble Jupiter, although many are thought to be much larger than our largest planet.

A rock falling through Earth's atmosphere from outer space is called a

A meteoroid is space debris that is made up of rock. A meteoroid that enters Earth's atmosphere and burns up is called a meteor. A meteorite is a meteor that survives the fall through Earth's atmosphere.

Which planet do most known extrasolar planets LEAST resemble

Mars

The inner planets such as Mars, Earth or Mercury. these are too small to identify in other systems and too close to the star.

Why do astronomers find it difficult to locate extrasolar planets with telescopes

Planets are considerably smaller than their parent stars, also they emit no light and are very close to the star. With all this combined, separating between the two with a telescope is very difficult.
