MOONS OF NEPTUNE

Neptune has 13 known moons, though most are small and orbit closer to Neptune than its rings. Triton is Neptune's only large moon with a diameter of 2,704 km, and Proteus and Nereid are Neptune's second and third largest moons, respectively.

Triton: The backward moon of Neptune

Voyager 2 discovered many of Neptune's moons in 1989, and took pictures revealing many previously unknown properties of Triton. Triton's icy, spherical surface reflects so much of the sunlight it receives that it is the coldest world in the solar system.
Triton is the only moon in the solar system with a retrograde orbit. This, along with Triton's high inclination relative to Neptune's equator, suggests that Triton may have been captured from interplanetary space.

The surface of Triton

Photos of Triton show a strange surface shaped by more than just impact cratering, although its many undisturbed craters suggest that major geologic activity has subsided. Regions on Titan's surface show evidence of past volcanic and tectonic activity. The internal heat source for Triton's geologic activity is not known, but it may involve tidal heating.
The sublimation of surface ices creates a thin, hazy atmosphereon Triton made mostly of Nitrogen. The atmosphere creates wind streaks on the surface, and unknown processes pump unusual plumes of gas and particles into the atmosphere.

Uranus' medium-size moons
(300 - 1,500 km in diameter)

5 medium-size moons orbit Uranus (from innermost to outermost):

• Miranda
• Ariel
• Umbriel
• Titania
• Oberon

Uranus' medium-size moons are made of ice and rock. Like other objects that formed far from the Sun, the ice is made up of ammonia, methane and water.
These moons pose several puzzles. Ariel and Umbriel are about the same size and density, but Ariel's young features indicate volcanic and tectonic activity, while Umbriel's largely cratered, uniform surface implies a lack of geologic activity. Titania and Oberon are also very close in radius, but show different levels of geologic activity. The faults on Titania indicate internal forces while Oberon's heavily cratered, icy surface shows few signs of movement.


A Canyon on Miranda

Voyager 2 came closest to Uranus' smallest moon, Miranda, as it passed by on its way to Neptune. The features on Miranda's surface are different from other jovian moons. With a mixture of old and new surfaces, Miranda shows relatively few craters but has a number of canyons up to 12 miles deep. Due to Miranda's odd surface features, scientists spectulate that there is an additional source of heat, such as tidal heating. The cliff walls seen in the inset are higher than those of the Grand Canyon on Earth.

Uranus' small moons

Uranus' smallest moons are its innermost satellites. Portia heads a group of 8 inner satellites. The Portia Group consists of Bianca, Cressida, Desdemona, Juliet, Rosalind, Cupid, Belinda and Perdita. The Portian orbit is slowly decaying due to tidal deceleration and may one day either break apart to form a planetary ring or could potentially collide with Uranus. Orbits of the other satellites in the Portia Group have a similar fate.

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune

Fun fact. Uranus could have been called Georgium Sidus in honor of King George III. Or Herschel in honor of planet's discoverer. But finally was chosen Uranus because since Saturn was Jupiter's father, the new planet should be named after Saturn's father. More useful information about this planet you can find here https://solarstory.net/planets/uranus

Uranus was the first planet to be discovered in modern history. It was actually discovered by accident in 1781 by William Herschel.
Like the other gas giants, Uranus has a very thick cloud cover and an atmosphere made up mostly of hydrogen, helium, methane, and ammonia. The trace amount of methane is what gives Uranus and its twin, Neptune, their blue color. Unlike Saturn and Jupiter, Uranus has a different internal structure.
The core of Uranus is probably composed of liquid rock. Then, farther up, the liquid rock slowly gives way to an ocean made mostly of hydrogen, helium, and water, with small amounts of ammonia and methane. This "ocean" accounts for most of Uranus's bulk. Then, the water slowly thins out into the bland, almost featureless atmosphere.
Uranus also has a system of about 11 rings - not nearly as large as Saturn's. Nine were found when Uranus passed in front of a bright star, the rings causing the star to temporarily disappear when they passed in front of it. This was the first time astronomers had detected rings around any planet other than Saturn. It was the first time, also, that astronomers had detected thin rings around any planet. The other two rings were found when Voyager 2 passed by.
Uranus also has 27 known moons, most of which little is known about.

Uranus has two main unique features. First, there is absolutely no detail in the cloud cover. Only when pushed to the maximum level of color enhancement and contrast on computers do scientists start to see small swirls in the atmosphere.
Second, Uranus is the only planet rotates on its side. This produces the strangest seasons of any planet in the solar system. For 21 years, Uranus's moons are seen as one would view a dart board, with one pole facing the sun. The next 21 years Uranus has its side to the sun, and the moons move up and down across the equator. then the cycle repeats itself starting with the other pole. Scientists aren't sure why this is, but they think that a large body smashed into it with such force that it pushed the planet over.
Mythology
Uranus was named for the ancient Greek god of the heavens. When Earth was first made, Uranus was the first thing she saw, and they fell in love.

Uranus was named after the Greek god of the sky. According to myth, he was the father of Saturn and the grandfather of Jupiter.

In our solar system:

Mercury
Venus
Earth
Mars
Jupiter
Saturn
Uranus
Neptune
Pluto*

About four times Earth's radius and fifteen times the mass.

That's only eight. Pluto, which used to be the ninth planet, was demoted from "planet" to "dwarf planet" a few years ago.
