Because they all condensed out of the same cloud of spinning dust and gas.

Jupiter Neptune
The planet that most extrasolar planets resembles Jupiter.

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.
An explosion disturbs the gas and dust in the nebula.
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.
star cycle
They were formed in supernovae.
That is called a "black hole".

Nebula, white dwarf, red giant, black hole
Because ice cubes are less dense than water.

Light from the stars they orbit makes it difficult to see them.
Stars like our sun and hydrogen bombs produce energy through nuclear fusion.

They don't understand how redshift affects stars.
