Stars and our Sun
• A star is a huge ball of gas that is very hot and that gives off heat,
light, and other energy that we need.
• Stars are classified by the elements that they absorb and their
temperature.

Planets
Mercury
-279 F at night and 801 F at day
Diameter 4879.4 km or 3,032 ml
Mercury is 28.5 million miles from the
sun
Mercury is a rock like planet
Mercury's core makes up a larger portion
of the planet surrounded by a mantle and
crust.
Mercury surprisingly has no moons unlike
most of the other planets in our Solar
System.
Mercury only takes 88 days to orbit the
sun because it is the closest to the sun.

Outer
Saturn
- 300 F
Diameter 120,536 Kilometers or 74,898 mi
890.7 million mi from the sun
Saturn is a gas giant and it has no solid
surface, it also has seven rings around it that
are made of ice and rock.
Saturn has a rocky core but it is considered a
gas giant.
Saturn is 1,503,000,000 km from the sun.
Saturn has 62 moons
Saturn is the sixth planet from the sun
Comets and Meteors
• Meteors are a small body of matter from outer space that enters
Earth's atmosphere.
• Comets are a celestial object consisting of a nucleus of ice and dust.
• A meteoroid is a small particle from an asteroid or comet orbiting the
sun.
• A meteor is a meteoroid that is observed as it burns up in the earth’s
atmosphere.
• A meteorite is a meteoroid that survives its passage through the
earth’s atmosphere and impacts the earth’s surface.
Gravity
• The force that attracts a body toward the center of the earth, or
toward any other physical body having mass. For most purposes
Newton's laws of gravity.
• Gravity impacts humans because without it people would float
around and jump high without gravity pulling them down.
• Mercury is smaller than all the other planets in our Solar System, but
it is dense. Because Mercury is so small, it has very little gravity. If you
weighed 68 kg on Earth, you would only weigh 25.7 kg on Mercury.
Technology
• A rover is a space exploration vehicle designed to move across the
surface of planets.
• Rovers impact humans because now we can
look at mars and other planets without putting
humans on the planets and risking there live
because they don’t have enough food and
water to stay.
