The Solar System

Front 1

Does not attract objects to itself

Back 1

“Clear the neighborhood”

Front 2

Does not clear the neighborhood, does not orbit a planet or dwarf planet, includes asteroids, meteoroids, and comets

Back 2

Small Solar System Bodies (SSSBs)

Front 3

Orbit a planet or dwarf planet, are also known as satellites

Back 3

Moons

Front 4

Giant ball of phasma that gives off energy

Back 4

Star

Front 5

Smallest planet, very dense; closet to the sun, but not the hottest because it has no atmosphere to retain heat

Back 5

Mercury

Front 6

Covered in thick clouds, but radar-mapping shows volcanic features and evidence of recent tectonic activity. Surface temperatures are hot enough to melt lead due to a very thick thick CO2 atmosphere (Runaway Greenhouse Effect!)

Back 6

Venus

Front 7

A magnetic field and spinning liquid iron core

Back 7

Earth

Front 8

Has thin atmosphere made mostly of CO2. Polar ice caps of CO2 and H20

Back 8

Mars

Front 9

Largest planet, fastest spin; Great Red Spot is a storm. Has 66 moons; 4 were discovered by Galileo

Back 9

Jupiter

Front 10

The rings are made of ice and rock particles

Back 10

Saturn

Front 11

Rotates on its side

Back 11

Uranus

Front 12

Has very fast winds, blue color (due to methane)

Back 12

Neptune

Front 13

This lies between the orbit of Mars and Jupiter

Back 13

The Asteroid Belt

Front 14

This lies beyond the orbit of Neptune

Back 14

The Kuiper Belt

Front 15

This is a spherical cloud that surrounds the solar system

Back 15

The Oort Cloud

Front 16

Irregular-shaped rocky bodies that may be left from the origin of the solar system. Craters on the moon and on the terrestrial planets are likely from asteroid impacts

Back 16

Asteroids

Front 17

Made of pieces of rocky and metallic materials held together by frozen gases. As they travel close to the sun, some iced evaporate and get blown by the solar wind, causing a tail to form

Back 17

Comets

Front 18

Small solid particles that travel through space. They burn up in our atmosphere producing a streak of light called a meteor (aka shooting star). If it doesn’t completely burn up, the piece of material that hits Earth is called a meteorite

Back 18

Meteoroids

Front 19

The movement of one object around another (orbit). The moon takes about 1 month to revolve around the Earth

Back 19

Revolution

Front 20

This is spinning on an axis. Because the moon also takes about 1 month to rotate, we always see the same side of the moon

Back 20

Rotation

Front 21

Originally thought to be “seas”. Darkest part of the lunar landscape. Filled with lava after meteorite impacts 3-4 billion years ago

Back 21

Maria

Front 22

A mars-sized object collided with Earth. Surface rocks/material were blasted off and later coalesced (clumped together) to form the moon

Back 22

The moon’s formation

Front 23

Occurs when earth’s shadow falls on the moon; moon will be a full moon phase

Back 23

Lunar eclipse

Front 24

Occurs when the moon’s shadow falls on Earth, the moon will be in a new moon phase

Back 24

Solar eclipse
