2. The voyager 2 was sent to take images of
Uranus. The voyager 2 discovered 10
moons and a few additional rings before
going to Neptune.

4. • The Atmosphere
• Like the atmospheres of Saturn and Jupiter, Uranus’s “surface” is covered by a
striped pattern of winds that circle its longitudes. This is cloaked, however, by the
envelope of methane that surrounds it. Another effect of the methane presence is the
absorption of red wavelength light which gives Uranus is turquoise appearance.
There’s more than just methane in the atmosphere: higher up in the stratosphere
hovers a hydrocarbon smog. Clouds of methane ice float low in the Uranian
troposphere.
The composition of Uranus’s atmosphere is 82.5 percent molecular hydrogen,
15.2 percent Helium, and 2.3 percent Methane. Trace amounts of Hydrogen
Deuteride exist, with possible aerosols of ammonia ice, water ice, ammonia
hydrosulfide , and methane ice.
