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.
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.
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.

Pressure caused by high temperatures are balanced by gravity
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.
They were formed in supernovae.
Nebula, white dwarf, red giant, black hole
Light from the stars they orbit makes it difficult to see them.
star of one stellar mass, red giant, planetary nebula, white dwarf
They don't understand how redshift affects stars.
Pressure and gravity
full moon
Matter was compressed into a single point and then exploded outward to form the universe - APEX
Distant stars give off less light
