Uranus
Uranus does not just revolve around the
sun; it rolls around the sun. The planet
is laying on its side. Its equator runs up
and down, and its poles are on its side.
Scientists do not know what pushed
Uranus over. Many say that one or more
space objects crashed into it, shortly
after the planet formed.
Neptune
Neptune has the fastest winds. These
wicked winds speed around the planet
at 500 metres per second, faster than
the winds on Jupiter. But that is not the
oddest thing about Neptune’s winds.
They blow backwards! Winds on the other
planets usually blow in the direction the
planet spins, or rotates. Not onNeptune.
