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.
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
They were formed in supernovae.
That it is Saturn's biggest moon and it has an atmosphere.
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
Matter was compressed into a single point and then exploded outward to form the universe - APEX
light from the they orbit makes it difficult to locate extrasolar planets with telescope
