? Moons also known as natural satellites are
astronomical bodies that orbit planets and
asteroids
? The Solar system has 196 known moons
? Many of them are named for mythological
characters except Uranus’ moons are named for
Shakespeare’s plays
? Most moons are probably formed from the discs
of gas and dust circulating around planets
? Mercury and Venus don’t have any moons

? The 1st moon to be discovered
? The 5th largest moon in the Solar system
? Radius: 1 737.5 kilometers (3.7x smaller than
Earth)
? The only place where a human being has
been beyond Earth
? Surface has numerous craters and light areas
(highlands) and dark areas (maria) that
represent rocks of different composition and
ages and are also old basins of lava
? Temperature varies between 127 °c and -173
°c

? Mars has two moons; Phobos

? Phobos is a bit larger than Deimos and it
orbits Mars three times a day
? Deimos takes about 30 h to orbit
? Both have a lumpy structure and are
heavily-cratered and covered in dust and
loose rocks

? Jupiter has 79 moons
? 53 named and 26 that are waiting
their official names

another planet are called the

moons because they were
found by Galileo Galilei in 1610. All of them are bright enough to be
viewed from Earth without a telescope.

Callisto is the 2nd largest of the Galilean moons and the 3rd largest
moon in the Solar System. It’s is similar to our Moon because the
surface is also heavily cratered.

Europa
Europa is the smallest moon of the Galilean moons and 6th largest in
the Solar system. Its surface is extremely flat and it contains mainly
water ice. Scientists thinks that Europa is the best place in the solar
system to look for alien life.

? Saturn has 53 confirmed moons and nine waiting confirmation.

Titan
Titan is Saturn's biggest moon and the only known world other than Earth where any sort
of liquid collects on its surface. Its surface is so cold which means the moon's surface is
water ice instead of rock. This means methane and ethane exist on Titan

Rhea
Rhea
Rhea is the second largest moon. It has a typical cratered surface. Its surface can be
divided into two geologically different areas because half of its surface is based on crater
density and the other half is icy.
3. The third biggest moon Iapetus
Iapetus
Iapetus
Iapetus is not perfectly round it’s a bit
flatten. It also has one bright icy side and one very dark side.
