B. Planets all orbit around the Sun.
C. Planets all have elliptical orbits that are nearly circular and lie close to the same plane.

A. Both comet types come from random directions in a spherical distribution around the Sun, but the long-period comets come from farther away.
B. Short-period comets come from some location near the ecliptic plane of the Solar System, and long-period comets come from farther away, with random directions in a spherical distribution around the Sun.
C. Both comet types come from some location near the ecliptic plane of the Solar System, but the long-period comets come from farther away.
D. Short-period comets come from a random direction in a spherical distribution around the Sun, and long-period comets come from farther away, in some location near the ecliptic plane of the Solar System.
Which of the following properties of Pluto would best help answer this question?
B. orbital period
C. surface temperature
E. apparent brightness
A. All objects that orbit the Sun should be reclassified as planets.
B. Pluto and Eris should be classified as planets because they are the largest, but none of the other objects should be classified as such.
C. Pluto, but not the other objects, should be classified as a planet because it is closer to the Sun than they are.
D. Pluto, but not the other objects, should be classified as a planet because that is the way it was classically defined.
E. There is no scientifically satisfying way to answer this question: we need a better definition of a planet that has some physical meaning behind it.
The three catagories to sort the following objects are
Planets, Dwarf Planets, and Not planet or dwarf
Saturn, Io, Eros, Ceres, Pluto, Eres, Earth
Dwarf planets: Ceres, Pluto, Eres
Not planet or dwarf: Eros, Io
B. All of the gas in the nebula collapses to the center to form the Sun, which then expels a piece of itself in a violent solar flare that is blown outward and becomes a planet.
C. Individual particles in the nebula stick together to form larger pieces which later collide with and stick to other pieces to gradually form larger objects, which eventually grow to the size of a planet.
A. were once part of a single protoplanet that was shattered by collisions.
B. have all undergone significant chemical evolution since formation.
C. used to be volcanic moons orbiting other planets.
D. occasionally grow large enough to become differentiated and geologically active.
The members of the asteroid belt were never part of one larger body. Instead, they formed by the same process of accretion that formed the rest of the planets. Several of these asteroids accreted enough mass to cause internal heat, thus differentiating the body and allowing some volcanically altered rock to accumulate on their surfaces.
Choose one or more:
A. the temperature in the early solar nebula
B. the age of the Solar System
C. the physical processes that controlled the formation of the Solar System
D. changes in the rate of cratering in the early Solar System
E. changes in the composition of the primitive Solar System
Meteorites are generally from rocks that have been orbiting the Sun with little change since their formation. Their structure and composition thus tell us not only about the age, but also temperature, composition, and the processes that brought the material together. Since meteorites are fragmented when they reach Earth’s surface, they cannot show changes in the rate of cratering in the early Solar System. Instead, intact bodies such as moons and asteroids reveal changes in rates of cratering.
A. Most of the material has already been stripped from the objects.
B. They are too far from the Sun.
C. The comas and tails are pointing away from Earth.
D. They are too close to the Sun.
Even comets only show tails when they are in the inner Solar System where the heat from the Sun begins to thaw the frozen material of the nucleus. KBOs never come close enough to the Sun for that to happen.
1) Patterns of motion for all objects in the system
2) Why compositions vary (terrestrial vs jovian planets, etc.)
3) How there can be so much debris left over (asteroids and comets)
4) How exceptions to the rules are possible (tilted planets, abnormal size moons, etc.)
Regarding motions, which of these IS supported by the Nebular Theory? Select ALL that apply.
a. The majority of the solar system is flat
b. Planets orbit in the same direction
c. We observe disks of gas and dust around other stars
a. there were no volatiles in the inner part of the accretion disk.
b. the volatiles on the inner planets were lost soon after the planet formed.
c. the outer Solar System has gained more volatiles from space since formation.
1. measures precise changes in a star’s position in the sky to look for slight motion caused by a planet’s orbit
2. looks for back and forth motion of a star caused by a planet’s gravitational influence; allows us to measure the mass of the planet
3. looks for very slight, periodic dimming of a star; allows us to measure a planet’s size
