What causes the tail of a comet

solar wind The heat from the sun

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.

What aspect of the gas giants has the biggest effect on their rings and satellites

The aspect of the gas giants that has the biggest effect on their rings and satellites is their gravity.

Why are temperatures on the gas giants so low

They are far from the sun.

What do all of the terrestrial planets have in common

They all have solid, rocky surfaces.

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.

Which best describes how the sun rotates

The sun rotates more slowly at its poles.

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.

Pluto dwells on the inner edge of the

Kuiper belt

When a rock falls from outer space all the way to the ground it is called

A meteorite.

The sun is located at one of the two in the shape of earths orbital path

The Sun is located in one of the foci [plural of focus] of the Earth's elliptical orbit.

A stream of plasma

coronal mass ejections

What causes the ion tail of a comet to form

Paynis.

In which layer of the sun are gamma ray photons produced-

The core
