Solar system PLANET
Mercury's orbit is
not a perfect
circle like most of
the other planets.
It's actually egg-
shaped. At times,
Mercury's orbit
brings it closer to
the Sun than
other times, while
all the other
planets that have
circular orbits are
always the same
distance from the
Sun.
Because Venus is so
close to the Earth, it
appears as the
brightest planet in
the night sky.
Scientists use the Earth to study all the
other planets. Since no human has ever
visited another planet, we have to use
what we know about the Earth, and try to
guess what the other planets must be like.
This is called Comparative Planetology.
Mars has higher mountains, and deeper
canyons than any other planet. The largest
canyon on Mars would stretch from New
York City to Los Angeles on the Earth. That
makes the Grand Canyon look tiny. It also
has the Solar System's biggest volcano,
Olympus Mons, which is nearly 3 times
larger than Mount Everest.
You can see four of
Jupiter's moons With a
pair of binoculars at
night. Also, Jupiter
spins really fast; it only
takes 10 hours to go
from night to day on
Jupiter. For this
reason, its middle has
been stretched out.
Rather than round it is
short and fat. Kind of
like when someone
spins pizza dough
really fast to stretch
it out. This planet
shape is called an
oblate spheroid.
Saturn is the
furthest planet
from Earth that
can be seen
without the help
of a telescope.
Since Uranus spins on its
side, its rings rotate up and
over the planet instead of
around the middle like the
rings of Saturn and Neptune.
Neptune's circular orbit is
offset from the Sun. At
times, Neptune's orbit takes
it further from the Sun than
any other planet in the Solar
System.

of the planets
