-
1 1/2 billion miles from the Sun
-
has an atmosphere of hydrogen and helium
-
has 11 rings
-
Uranus may have been knocked on its side by an object as big as earth
because it doesn't spin on its axis like all the other planets
-
on its journey around the sun one pole receives 42 years of daylight
while the other has a 42 year night
-
it contains large amounts of water, methane, and ammonia may be the
result of collisions with comets
-
methane clouds rap around the planet in a greenish blue envelope any
features in the atmosphere so we don't know for sure what Uranus' surface
is like
-
there are two theories-- (1) the atmosphere thickens, changing to a
watery slush near the planet's core,or perhaps an ocean of super hot water
and ammonia lies between the atmosphere and the core
-
the temperature is -220o C
-
it may contain diamonds
-
colliding comets may have helped form Uranus
-
it is greenish blue because the methane in its atmosphere absorbs red
wavelength in sunlight
-
there are 15 moons on Uranus
|
-
it travels around the sun in 84 Earth years
|
-
if you weigh 100 lb. on Earth you would
weigh 91 lb. on Uranus
-
if you are 10 years old on Earth you would
be 1 1/2 months old on Uranus
