Important facts of Uranus:
Uranus location in the Solar System:
The
seventh planet from the Sun is Uranus. It’s named on the Greek god of the sky,
Uranus, who, according to Greek mythology, was the grandfather of Zeus
(Jupiter) and father of Cronus (Saturn). It has the third-largest planetary
radius and fourth-largest planetary mass in the Solar System. Uranus is similar
in composition to Neptune, and both have bulk chemical compositions which
differ from that of the larger gas giants Jupiter and Saturn.
Like
the other giant planets, Uranus has a ring
system, a magnetosphere, and numerous
moons. The Uranian system has a unique configuration because its axis of
rotation is tilted sideways, nearly into the plane of its solar orbit. Its
north and south poles, therefore, lie where most other planets have their
equators.
This distance is equivalent to 19.8 Astronomical
Unit.
Uranus Diameter
is 50,724 km.

Five Important facts of Uranus
Uranus Rotation & Revolution
1. The average distance of the Uranus from
the Sun is about 1.8 billion miles (2.9 billion kilometers).
2. Uranus rotates counter clockwise axis.
3. The Uranus takes 17 h 14 min 24 s (0.72
days) to complete one rotation.
The Uranus rotates counter clockwise on
its axis at a speed of 2.59 km/s (9,320 km/h)
4. Uranus takes 84.0205 Year ( 30,688.5 day) or
42,718 Uranian solar days to complete one revolution of the Sun.
The Uranus revolves around the Sun and
at a speed of 6.80 km/s (24480 Km/h) or 15,233 miles/h
5. The Uranus's axis tilts to 97.77 degrees
Physical characteristics
Uranus's mass is about 14.5
times that of Earth, making it the least massive of the giant planets. Uranus diameter
is slightly larger than Neptune's at about four times that of Earth. After
Saturn Uranus is a least dense planet, resulting density of 1.27 g/cm3.This
value indicates that it is made primarily of various ices, such as water,
ammonia, and methane. Hydrogen and helium constitute only a small part of the
total, with between 0.5 and 1.5 Earth masses. The remainder of the non-ice mass
(0.5 to 3.7 Earth masses) is accounted for by rocky material..
Atmosphere of Uranus
Uranus's atmosphere is similar
to Jupiter's and Saturn's in its primary composition of hydrogen and helium,
but it contains more "ices" such as water, ammonia, and methane,
along with traces of other hydrocarbons. Uranus has the coldest planetary atmosphere in the Solar System, with a minimum temperature of 49 K (−224 °C; −371 °F),
and has a complex, layered cloud structure with water thought to make up the
lowest clouds and methane the uppermost layer of clouds. The interior of Uranus
is mainly composed of ices and rock.
Life
No evidence for life has been
found on Uranus.
