COMPOSITION
this planet is similar to Earth in size and mass.
Venus
This planet's axis of rotation is tilted almost 98 degrees
Uranus
is a meteoroid that reaches Earth’s surface without burning up completely
A meteorite
This planet's moon is the only other body in the solar system on which a human has set foot
Earth’s
A cool, dark spot on the sun is a(n)
sunspot
This planet has a cratered surface of volcanic rock and a partially molten core.
Mercury
This planet in the solar system has the fastest rotation
Jupiter
is a bright streak of light that results when a meteoroid burns up in Earth’s atmosphere.
A meteor
is a small, rocky object that orbits the sun. Most asteroids are found in the asteroid belt. Some are found in the orbits of planets, and some cross the orbits of Earth and Venus.

Earth
This planet's largest moon, Titan, has lakes filled with methane and other compounds and it has an atmosphere that is denser than Earth’s.
Saturn
is a body that orbits the sun and has enough mass to be round, but has not cleared its orbital path.

Convection
What is the process in which energy is transferred as electromagnetic waves?
radiation
The surface of this planet is composed largely of dark volcanic rock with boulders covered with an orange-red powdery dust.
Mars
This planet's moon, Miranda is active.
Uranus
is a roughly spherical region that forms the outer reaches of the solar system.
