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.

What is not standing in the way of astronomers getting a good view of distant stars

Forgetting to remove the telescope lens cap is not usually the problem.

The answer to this multiple choice question is "red shift" which is actually a useful phenomenon in viewing and analyzing the light from very distant stars. Light is shifted in wavelength by the movement of stars toward or more typically AWAY from the observer, or by moving through strong gravitational fields.

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.

The farther a star is away from earth the more it is

red shifted

Hydrogen bombs and stars both produce energy with nuclear

fusion

What begins the process of solar system formation

Gas and dust in a nebula is disturbed by an outside force

It takes an extremely high temperature for nuclear to occur inside the sun

Not nuclear, it takes an extremely hight temperature for Fusion to occur with in the sun or any other star.

ADDED: Yes "nuclear". Fusion is one of the two type of nuclear reaction, the other being Fission.

What aspect of gas giants is most responsible for their low temperature

Their distance from the sun

What is true about the satellite titan

That it is Saturn's biggest moon and it has an atmosphere.

Which group of planets has more in common the inner planets or the outer planets

All the inner planets are terrestrial planets.

Which best describes the beginning of the big bang

A blowing of a balloon best describes the BIG BANG best

Select the star life cycle that is accurate.

star of one stellar mass, red giant, planetary nebula, white dwarf

What two things balance to maintain the shape of a star

Pressure and gravity

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

light from the they orbit makes it difficult to locate extrasolar planets with telescope

Which contributes to the lack of evidence of the period of heavy bombardment on earth

Plate movements
