Planets & Distance
Essential Questions:
• What are the major components of the
universe? (SPI 0601.6.1)
• How does the distance of objects in space
from Earth affect how they appear? (SPI
0607.6.2)
Terrestrial Planets
•
•
•
•
Mercury
Venus
Earth
Mars
Terrestrial Planets
• The inner planets closest to the Sun.
• “Earth-like” planets because they are small,
dense, and rocky.
Mercury
• Closest planet to the Sun.
• Has no moons.
Venus
• Almost the same size, mass, and density as
Earth.
• Earth’s “sister planet”
• Hottest planet in the solar system due to the
greenhouse effect and a dense atmosphere.
Earth
• Known as the oasis in space and has the right
condition for plants and animals.
Mars
• “Red-planet”
• Cold
• Site of the Olympus Mons-highest mountain in
the solar system.
Gas Giants

•
Jupiter
Saturn
Uranus

Gas Giants
• The outer planets.
• Very large and do not have any known solid

Gas Giants vs. Terrestrial Planets
Jupiter
• The largest planet in the solar system.
• Has a permanent storm on its surface-Great
Red Spot.
• Has at least 61 moons.
Saturn
• Planet with the largest rings.
Uranus
• Tipped on its side at a

Neptune
• Known as the blue world.
Pluto
• Now known as a dwarf planet.
• Does not fit into characteristics of terrestrial
or gas.
Distance
• The closer a planet or object to Earth the
larger it looks.
• The father away a planet or object is to Earth
the smaller it looks.
