Here isa picture of Uranus
Like Jupiter and Saturn, Uranus is a gas giant. But Uranus
is a little different. Unlike all the other planets and most of
the moons in our Solar System, Uranus spins on its side. It
is believed that long ago a very large object smashed into
this planet. The crash was so powerful that it completely
changed the direction of Uranus' planetary rotation.
However, a more recent theory is that the extreme tilt of
Uranus' axis may have been caused by a large moon that
was slowly pulled away from the planet by another large
planet long ago when our Solar System was still new.
• William Herschel discovered Uranus on
March 13, 1781.
• Uranus was named after the Greek god
deity who was the god of the sky

• Uranus is the third largest planet in the solar system, after Jupiter
and Saturn. Uranus is about four times bigger than Earth. Its
diameter at the equator is about 31,763 miles 51,118 kilometers as
measured at the level of the atmosphere where the pressure is the
same as at sea level on Earth. The planet is slightly larger than
Neptune but Neptune is about 1.2 times more massive. Uranus's'
density is quite low only about 1.3 times that of water, compared
with 1.6 for Neptune and 5.5 for Earth.

• Uranus is shrouded in an icy cloud layer made up of
frozen methane, ethane, and acetylene circling this
planet at about 185 mph (300 kph. Uranus' icy and cold
atmosphere consist of 83% hydrogen,15% helium, and
• Uranus has a molten rocky core about 10,500 miles
(17,000 km) in diameter and about 12,500°F (6927°C).
This core may have a mass five times greater than the
mass of the Earth.
Surface Conditions or Uranus
• Uranus is not the farthest planet from the
Sun but it is the coldest planet in the Solar
• The average temperature of the surface of
Uranus is 49° Kelvin or -224° Celsius.
• Uranus is so cold because its core.Uranus
is only 5000° K, compared to Jupiter,
which as a core temperature of 30000° K.
• Uranus has 27 named after characters from the works of
William Shakespeare and Alexander Pope. Scientists
believe that Uranus has more than 30 moons but they have
not been discovered yet
• Moon names

Setebos, Mab, Pertida, Cupid, Francisco, Ferdinand,
Oberon, Titania, Umbriel, Ariel, Miranda, Puck, Rosalind
Portia, Juliet ,Desdemona ,Cressida, Bianca ,Ophelia and
• Uranus has different rings than Jupiter and Saturn.
Uranus's rings are very small and spaced out so it looks
like there are several skinny rings with big gaps in-
• Astronomers think that the rings of Uranus are very
young, and probably formed recently, and not with the

What would happen if a human
went to Uranus?
If a human went on Uranus they would freeze because of
the low temperatures on Uranus. A human would also
choke because the extremely low oxygen levels. In order to
explore Uranus safely a human would need an oxygen tank
and a body warmer along with probably 200 winter coats.
