Solar System Formation
This theory says the Sun and planets formed from a rotating cloud of gas and dust.
Solar Nebula Theory
Small, dense, rocky planets located close to the Sun.
Terrestrial Planet
The moon did not likely form at the same time as the earth because it is too this.
Big
This is the largest of Jupiter's moons
Ganymede
The planet famous for its spectacular ring system made of small orbiting particles.
Saturn
Tiny solid particles mixed in with the gases of the early solar nebula.
Interstellar Dust
The planet that orbits the Sun in the opposite direction of all the others.
Venus
Dark, flat basaltic plains on the Moon (also called “seas”).
Maria
The huge, long-lasting storm in Jupiter’s southern hemisphere.
Great Red Spot
The gaps in Saturn’s rings are caused by the gravitational influence of these objects.
Moons
Name for the boulder-sized objects that formed by clumping before planets existed.
Planetesimal
Greenhouse Effect
Elevated, heavily cratered regions on the Moon made of breccia.
Lunar highlands
The four largest moons of Jupiter were discovered by this scientist
Galileo
The planet that rotates on its side, likely due to early impacts.
This type of planet does not orbit our sun
Exoplanet
The Red Planet, known for its iron oxide surface and Olympus Mons.
Mars
What is the first stage in the formation of the moon?
The freezing of the original crust
The layer inside Jupiter responsible for its extremely strong magnetic field.
Metallic hydrogen
A windy planet, known for its Great Dark Spot.
Neptune
NASA mission that showed our solar system arrangement is relatively rare compared to many others with “hot Jupiters.”
Kepler
Name two points of evidence that points to why Mars may have had ancient flowing water
Valleys carved by floods, ice within 1 m of the surface, conglomerate rocks akin Earth, seasonal river streaks
This is the name for debris thrown out during an impact
Ejecta
The most volcanically active body in the solar system (one of Jupiter’s moons).
Io
The moon of Saturn that shows cryovolcanism (ice volcanoes).
Enceladus
