What does the term "Solar System" mean? - correct answer ✔ ✔ The
Sun, the planets, and all of their moons
What does the term "Universe" mean? - correct answer ✔ ✔ The
totality of all space, time, energy, and matter
Earth is 1 AU from the Sun. What is the maximumpossible separation
between Earth and Mars? (Hint: Mars is the next farthest planet from the
Sun) - correct answer ✔ ✔ 2.5 AU
A 'light year' is a measure of: - correct answer ✔ ✔ distance
Stars are... - correct answer ✔ ✔ balls of plasma which produce
energy by nuclear fusion.
Planets are.. - correct answer ✔ ✔ rocky, icy, or gassy, and they
don't produce much energy.
,Why is Pluto no longer considered a planet? - correct answer ✔ ✔ Its
orbit is full of other stuff
Definition of the term "planet" - correct answer ✔ ✔ Planets must
have cleared their orbits. That is, there can't be a lot of other stuff
orbiting the parent star in orbits very similar to the planet.
A moon is ... - correct answer ✔ ✔ any large body which orbits a
planet.
Titan is a rocky/icy object with an atmosphere and liquid on its surface.
It is spherical in shape, has a clear orbit, and orbits Saturn. Titan is a ... -
correct answer ✔ ✔ moon
Ceres orbits the Sun in the asteroid belt between Mars and Jupiter. It is
large enough to be spherical. Ceres is a... - correct answer ✔ ✔ dwarf
planet
A solar system consists of ... - correct answer ✔ ✔ a star orbited by
planets, moons, and lots of debris (comets, asteroids, dust)
,The Inner Solar System... - correct answer ✔ ✔ Mercury, Venus,
Earth, Mars
The Outer Solar System... - correct answer ✔ ✔ :Jupiter, Saturn,
Uranus, Neptune, many dwarf planets & comets
How many stars are there in our Solar System? - correct answer ✔ ✔
one, the sun
The terrestrial planets are called - correct answer ✔ ✔ Mercury,
Venus, Earth, Mars

The Jovian planets are - correct answer ✔ ✔ gaseous, larger, and
farther away from the Sun
Compared to planets in the inner Solar System, planets in the outer Solar
System generally - correct answer ✔ ✔ are made of lighter elements
, What is it like on Mercury - correct answer ✔ ✔ No atmosphere,
highly cratered surface, Rocky exterior with a huge iron core
What is it like on Venus - correct answer ✔ ✔ Thick CO2
atmosphere, lots of (possibly) active volcanoes. About the same size as
Earth, Runaway greenhouse effect makes it even hotter than Mercury,
Rains acid, No moons
What is it like on Earth - correct answer ✔ ✔ Wet planet, Unusually
big moon•Surface and atmosphere heavily modified by life
What is it like on Mars - correct answer ✔ ✔ Very thin CO2
atmosphere•Many huge, extinct volcanoes, Was probably warmer and
wetter in the past, Many surface features probably carved by water, No
life known to date
The planet with the highest average surface temperature is... - correct
answer ✔ ✔ Venus
Scientists announce the discovery of a new planet in another solar
system. The planet is the same size as Earth and orbits a star just like the
Sun at a distance of 0.9 AU. Based on our own solar system, what can
