One Orbit around the Sun takes = 30,685 Earth days (Just over 84 Earth Years).

Atmosphere on Uranus = 83% Hydrogen, 15% Helium, and 2% Methane. The surface of Uranus is made of blue-green clouds of tiny crystals of Methane that has frozen out of Uranus' atmosphere. About 4,700 miles below those clouds, it is believed there is an ocean of liquid water with crystals of ammonia ice.

Speed of Travel during orbit = Approximately 15,233 MPH

Distance of Travel (one Orbit) = Approximately 11,218,581,890 Miles (over 11.2 Billion Miles)

Natural Satellites (Moons) = Uranus has 21 known satellites. The largest, Titania, is only 490.2 miles in diameter.

Planet Saturn

Saturn is the 6th closest planet to the Sun


Diameter of Saturn =74,900 Miles

Distance from Saturn to the Sun = 840,440,000 miles at its closest and 941,070,000 miles at its furthest.

Distance from Saturn to Earth = 739,680,000 miles at its closest.

One Rotation of Saturn takes = 10 Hours 39 Minutes. Saturn's extreme rotation speed causes the planets shape to bulge at its equator. The diameter of Jupiter at its equator is about 8,000 miles larger than it is at the poles.

One Orbit around the Sun takes = 10,759 Earth days (about 29-1/2 Years).

Atmosphere on Saturn = Most scientist believe Saturn is one large ball of gas with no solid surface, but there is reason to believe that Saturn has a solid, hot, inner core of iron and rocky materials. There is an outer core that is believed to be Ammonia, Methane and Water. Surrounding that outer core is a layer of highly compressed, liquid metallic hydrogen. Above this lies a layer of hydrogen and helium.

Speed of Travel during orbit = Approximately 21,675.91 MPH

Distance of Travel (one Orbit) = Approximately 5,597,065,734 Miles (Almost 5.6 Billion Miles)

Rings = There are 7 rings around Saturn, made up from thousands of smaller ringlets. These ringlets are made of billions of chunks of ice that range from the size of a particle of dust, to larger chunks about 10 feet across.

The largest ring can measure as much as 180,000 miles across. There is a space between the rings of about 2,000 miles. The thickness of the rings range from 6,60 feet to 9,800 feet.

Natural Satellites (Moons) = Saturn has 25 larger satellites that are at least 6 miles across and several other smaller satellites. The largest, Titan, is 3,200 miles in diameter. Titan is larger than two of the planets, Mercury and Pluto.

Planet Jupiter

Jupiter is the 5th closest planet to the Sun.


Diameter of Jupiter = 88,846 Miles

Distance from Jupiter to the Sun = 460,000,000 miles at its closest and 508,000,000 miles at its furthest.

Distance from Jupiter to Earth = 365,000,000 miles at its closest.

One Rotation of Jupiter takes = 9 Hours 56 Minutes. Jupiters extreme rotation speed causes the planets shape to bulge at its equator. The diameter of Jupiter at its equator is about 7% larger than it is at the poles.

One Orbit around the Sun takes = 4,333 Earth days (almost 12 Years).

Atmosphere on Jupiter = 86% Hydrogen, 14% Helium, with very tiny amounts of methane, ammonia, phosphine, water, acetylene, ethane, germanium, and carbon monoxide

Speed of Travel during orbit = Approximately 29,236.75 MPH

Distance of Travel (one Orbit) = Approximately 3,040,387,928 Miles (Over 3 Billion Miles)

Rings = 3 Very thin Rings (Much fainter than the rings of Saturn).

Natural Satellites (Moons) = Jupiter has 16 satellites that are at least 6 miles in diameter, with many smaller ones. The four largest, known as the Galilean satellites, are - Io, Europa, Ganymede, and Callisto.

Other Notes = Jupiter has very little solid surface. Instead, it is a large ball of gas, its surface, a very dense layer of different colored clouds.

Jupiter has a large mass of swirling gas, known as the Great Red Spot, that spans 24,860 miles across (About 3 times the diameter of the Earth). The outer edge of the Great Red Spot travels at about 225 mph.

Jupiter's gravity is approximately 2.4 times stronger than on Earth. so something weighing 100 lbs on Earth would weigh 240 lbs on Jupiter.

Sunrise to Sunrise on Mercury = 176 Earth Days

One Orbit around the Sun takes Mercury = 88 Earth Days

Atmosphere on Mercury = Mercury has very little in the way of gases in its atmosphere. From the planet, the sky would be black, even in the day. Some scientists think that you would even be able to see stars during the day.
