How Planets are Formed
By Ryan Koeberl
Generalization
• Large groups of gasses, debris, old stardust,
and other miscellaneous things come together
in space.
• In the center a star forms, the debris revolves
and soon forms planets and other celestial
objects.
• The ball of gases, and debris collapse from its
own gravitational pull.
• What was a ball now forms into a huge disk of
dust and ice with a central star.
• As the disk picks up rotational speed it’s
diameter gets smaller and more dense.
Planet formation
• As all the ice, dust and various debris is orbiting
the central star, the stuff starts crashing into each
other, and starts combining together.
• Soon the small dust particles turn into large
pieces of rock and ice, and keep growing.
• As they get bigger and bigger, they keep colliding
until they form into huge masses of rock.
• “The dust bunnies under your bed grow in a
similar way”(Scott Kenyon)
• There are two different type’s of gaseous
planets. There are hydrogen based Jovian's,
and compound gas planets.
• Hydrogen based gas planets are simply failed
sun’s, in our solar system there are two;
Jupiter and Saturn.
• The compound gas planets form the same way
as terrestrial planets except with gases.
Jovian planet formation
• Gaseous planets form in a similar way to terrestrial planets.
• The Gases gather around a large asteroid in space by
gravity and slowly start to grow more dense.
• The rock becomes the center of the planet as the gases
keep surrounding it.
• As the planet grows bigger, its gravitational pull increases,
dragging in more gasses.
• Since Gaseous planets are farther away from their central
star compared to terrestrial planets for the most part, the
gases take longer for the radiation to disperse, explaining
why they may grow larger then rocky planets.
Hydrogen Planet’s.
• Saturn and Jupiter are both failed sun’s. This
means they’re made up of Hydrogen.
• The most likely reason that these two planets
aren’t sun’s is because they are too small to
ignite.
