Terrestrial and Jovian
2 types of planets
small and rocky (Mercury, Venus, Earth, and Mars)
large and hydrogen-rich (Jupiter, Saturn, Uranus, and Neptune)
our solar system formed from a collapsing, giant, swirling cloud of gas and dust.
1st stage of solar system development
Spherical, very cold, rotating slightly, and a few light years in diameter.
2nd stage of solar system development
Nebula shrinks, gravity increases, it collapses and heats. As it collapses, it rotates faster and clumps of gas collide and merge. Assumes the shape of a disk.
6 trillion miles
1 light year=
sun's percentage of the solar system by mass.
elements and compounds begin to solidify out of nebula depending on temperature.
only rocks and metals condensed within 3.5 AU of the sun.
small grains stick to one another via electromagnetic force until they are massive enough to attract via gravity.
much smaller baby planets.
form rocky planets
planetesimals which form inside the frost line...
form icy planetesimals
planetesimals which form beyond the frost line...
capture H/He to form gas planets.
these icy planetesimals then...
any planet outside of our solar system.
detecting exoplanets by observing how its star wobbles due to the planet's gravitational tug.
detecting exoplanets by measuring the Doppler shift of the star's spectrum.
detecting exoplanets by observing the change in brightness as the planet eclipses the star.
