Planet Formation & Evolution
This planet formation model starts with small solid particles sticking together.
What is core accretion?
This planet is denser because it is mostly rock and metal.
What is Mercury?
These objects are mostly rock and metal and often irregularly shaped.
What are asteroids?
This method detects planets by measuring dips in starlight.
What is the transit method?
Convert 3.6×10^ 5 into standard form
What is 360,000?
This fast formation model involves gravitational collapse of gas in the disk.
What is disk instability?
This planet’s extreme winds are powered by internal heat.
What is Neptune?
Comets are valuable because they preserve this type of material.
What is primitive early solar system material?
This detection method observes stellar wobble.
What is radial velocity?
Write 45,000,000 in scientific notation
What is 4.5×10^7?
This concept estimates the minimum mass needed to form the solar system.
What is the Minimum Mass Solar Nebula?
This gas giant has the most prominent ring system.
What is Saturn?
This asteroid’s structure suggests many asteroids are rubble piles.
What is 25143 Itokawa?
Combining transits and radial velocity allows calculation of this.
What is planet density?
The acceleration of a 5 kg object experiencing a force of 25 N.
What is 5ms^-2?
The process where planets change their orbital distance after forming.
What is planetary migration?
This moon shows evidence of cryovolcanism.
What is Triton?
This comet was intentionally impacted by a spacecraft.
What is Tempel 1?
This method works best for large planets close to their stars.
What is the transit method?
A hockey puck slides on ice and keeps moving until friction slows it down. Which Newton’s Law explains this?
What is Newton's first law?
The region beyond which ices could condense, allowing gas giants to form.
What is the frost line (snow line)?
This planet’s storms last for centuries due to lack of a solid surface.
What is Jupiter?
This Kuiper Belt object is extremely unchanged since formation.
What is Arrokoth?
This type of exoplanet orbits very close to its star.
What is a hot Jupiter?
According to Wien’s Law, hotter objects emit light with this property.
What is shorter wavelength?
