Answer 1

ANSWER NO. 1

Distance from Sun: 36,000,000 miles
Diameter: 3,032 miles or about 1/3 that of Earth

Number of moons: 0

Length of year: 88 Earth days

Temperature: -279°F to 800°F

Mercury is a ball of rock with an iron core.

Mercury is the planet closest to the Sun. Its greyish surface is covered with craters made by objects that hit the planet. Mercury has no atmosphere and no water, and the surface would be very unpleasant to be on. The side of the planet that faces the Sun gets very hot, and the side that faces away from the Sun gets very cold.

ANSWER NO. 2

Saturn is a gas giant. It's structure is very similar to Jupiter's. The core is composed liquid rock. Next comes a layer of liquid hydrogen. It is under such high pressure that the nature of the hydrogen changes, and is able to conduct electricity like metal. This generates the planet's magnetic field.

The layer on top of this is ordinary liquid hydrogen. Next, the hydrogen thins out into the gaseous atmosphere. It is composed of mainly hydrogen and helium with trace amounts of methane, water, ammonia, and hydrogen sulfide.

Interestingly, Saturn creates some of its own heat, but in a much different way than Jupiter. Scientists believe that the hydrogen and helium are slowly separating out, like vinegar and oil when left to sit. In Saturn's case, the heavier helium is slowly making its way through the hydrogen, generating heat (from friction) as it goes.

Saturn has something like Jupiter's Great Red Spot, but it is a Great White Spot. Nothing is currently known about the phenomenon, but it is probably similar to the Great Red Spot in the way it has formed. Besides this, Saturn's outer atmosphere is not nearly as turbulent as Jupiter's. This is because, being about two times farther away from the sun, it receives approximately 1/4 as much as energy from it. Less energy means that there is less to power atmospheric phenomenon.

Saturn is basically one big atmosphere - as far as we know, there is no real surface to the planet. Its composition is nearly all H2; the rest is approximately:

H2: 96.3±2.4%
He: 3.25±2.4%
CH4: 0.45±0.2%
NH3: 0.0125±0.075%
HD: 0.011±0.0058%
C2H6: 0.0007±0.00015%

Besides this, aerosols of ammonia ice, water ice, and ammonia hydrosulfide exist in the atmosphere

The temperature at 1 bar is approximately 134 K, and at 0.1 bar it is 84 K. The density at 1 bar is 190 g/m3. Below 30° latitude, wind speeds range up to 400 m/s, and above that only 150 m/s. The scale height of the Saturnian atmosphere is about 59.5 km.

Saturn has a few unique features:
First, it is the least dense of all the planets. If there were a bathtub big enough to fit Saturn in, the planet would float.
Second is Saturn's magnificent ring system. This system has four sections. The farthest out, F, was discovered during the Voyager mission. Moving towards Saturn, next is the A section, and this section makes up about half the diameter of the entire system. Then comes the Cassini Division, between A and B, which is the large gap visible in most photographs. Next is the B ring, which has raised parts, caused by the planet's magnetism. These appear as spokes. In-between B and C, there is a small division called Enck's Division. The C ring is transparent. Farther in, there are very small ring particles which are slowly spiraling in towards the planet.

The rings were probably formed relatively recently - several thousand years ago - when two of Saturn's satellites crashed together. The ring systems of the other gas giants probably formed the same way, only much earlier, which is why they are mostly gone; most of their rings have fallen into their planet's atmosphere. In about 100,000,000 years, Saturn's rings will probably be gone, too. See the table below for data on its rings.
Another interesting property of Saturn is how it generates heat. As seen in the table below, the average temperature of Saturn is approximately 130 K. However, due to the equation for thermal equilibrium (below), it should only be about 80 K. This extra heat is generated due to its gas slowly separating. Like an oily salad dressing, the gases in Saturn's atmosphere are very slowly separating, with the lighter gas rising up and the heavier gas falling down. As this happens, friction between the molecules heats the gas, accounting for the extra heat.

Tp = Tsun(1-a)^1/4(Rsun/2d)^1/2

ANSWER NO. 3

These are the four Galilean satellites. They are named so because they were the only four moons that Galileo was able to see. They are also the largest of Jupiter's moons. From top-left in a clock-wise direction, they are Ganymede, Callisto, Europa, and Io.

If Ganymede were not bound to Jupiter, it would be considered a planet in its own right. It is actually bigger than Mercury, being 390 km (234 miles) larger in diameter. It has heavily cratered dark regions, with lighter expanses in-between. Geologists think that it used to have plates, like the Earth, but they froze together soon after Ganymede's birth.

Callisto, the outermost of the Galilean moons, is almost an exact twin of Mercury in size and appearance. Every square mile is covered with craters or other signs of bombardment. Other than that, there are no distinct characteristics

Europa, closer to Jupiter than Ganymede, is the smoothest natural body in the solar system. It resembles a billiard ball until seen very close-up. At that distance you can start to see dark, deep, and narrow cracks. In scale, though, the relief is no bigger than a line on a billiard ball made with a felt-tipped marker. Geologists think that Europa has liquid water underneath the icy surface - and possibly life.

Io, closer yet, is commonly compared to a pizza. Its volcanoes make it the most active world in the solar system. They spew out the sulfuric acid that gives Io its many colors. They also make Io one of the only three moons with an atmosphere in the solar system. Saturn's Titan and Neptune's Triton are the other two moons. Io is similar in size and composition to our moon. Io is caught in the middle of a tug-of-war between Jupiter and the other moons. Tension has melted the interior and raised the surface temperatures so high that scientists calculated that it generates the most heat for its size of any body in the solar system, except for the sun.

Other Moons

There are 57 other moons that have been discovered around Jupiter. There are four closer than Io. Their names, in order from Jupiter are Metis, Adrastea, Amalthea, and Thebe. Still in order after the Galilean Satellites are recently discovered Themisto, Leda, Himalia, Lysithea, and Elara. Then there are four more recently discovered moons, Ananke, and three more moons, of which scientists know little about. After these seven come Ananke, Carme, Pasiphaë, and Sinope, with two more moons in-between Pasiphaë and Sinope. After Sinope, 12 more moons are found.

The outer 33 moons all orbit Jupiter in a direction opposite (except for J/2003 J20) to that which Jupiter spins, which leads scientists to believe they are captured asteroids.

The largest non-Galilean moon is Amalthea, being 262 km (163 miles) at its widest diameter.

The innermost two moons, Metis and Adrastea, patrol the outer edge of the rings, their small gravity being enough to keep the particles from flying out.

Nearly all of the moons that have been discovered in the last few years orbit retrograde to the direction of Jupiter's rotation , indicating that they are most likely not native to the system. They are also very small. Those that have not yet been given names will eventually be given names by the International Astronomical Union, the only official naming group.

ANSWER NO. 4

Neptune is the eighth planet from the Sun and the fourth largest (by diameter). Neptune is smaller in diameter but larger in mass than Uranus.
orbit: 4,504,000,000 km (30.06 AU) from Sun
diameter: 49,532 km (equatorial)
mass: 1.0247e26 kg

Neptune's Satellites
Neptune has 8 known moons; 7 small ones and Triton.

ANSWER NO. 5

Saturn is currently known to have 56 moons, many of which were discovered very recently, and 3 additional un-confirmed moons. However, a precise number of moons can never be given, as there is no objective dividing line between the anonymous orbiting fragments that form Saturn's ring system and the larger objects that have already been named as moons.

Before the Space Age, 9 moons were known to orbit Saturn.
In 1980, the Voyager space probes discovered 9 more moons in the inner Saturnian system.
A survey starting in late 2000 found 12 new moons orbiting Saturn at a great distance in orbits that suggest they are fragments of larger bodies captured by Saturn's gravitational pull (Nature vol. 412, p.163-166).
The Cassini mission, which arrived at Saturn in the summer of 2004, discovered three small moons in the inner Saturnian system as well as three suspected but unconfirmed moons in the F Ring. This increased the total to 37 moons, confirmed and unconfirmed.
On November 16, 2004, Cassini scientists announced that the structure of Saturn's rings indicates the presence of several more moons orbiting within the rings, but only one, Daphnis, has been visually confirmed so far (its confirmation was announced on May 6, 2005).[1].
On May 3, 2005, astronomers using the Mauna Kea Observatory announced the discovery of 12 more small outer moons [2][3].
On June 30, 2006, astronomers using the Subaru 8.2-m telescope announced the discovery of 9 more small outer moons [4].
The spurious satellite Themis, "discovered" in 1905, does not exist.

ANSWER NO. 6


Uranus’s moons have had a long and tangled history. The first two moons, Titania and Oberon, were discovered in 1787 by the man who had discovered Uranus six years earlier, William Herschel. He named them after the king and queen of fairies in Shakespeare’s A Midsummer Night’s Dream, provoking a protest from the German ambassador (among others) who felt that the satellites should be given a more international and classical name. The name stuck, however, and now all of the moons of Uranus have been given the names of characters drawn from the works of either Shakespeare or Pope.
Naming the moons of Uranus, however, proved less troublesome than keeping track of them. Most are so small that they cannot be detected from Earth. Scientists were tracking the small satellites until the Hubble Space Telescope could be launched. But by the time Hubble sighted Uranus, Ophelia and Cordelia were lost. Due to the influence these moons exerted on the rings, however, they were eventually found again. A decade later, scientists going over the pictures taken by Voyager 2 discovered another moon. Several years later another was found. Now Uranus boasts 21 moons—five more than the leading contender, Saturn, which has fifteen. It is likely that at least one more small satellite is still hiding somewhere in the complicated web of moons and rings that encircle Uranus. In order from the planet, the satellites are 1999U3 (still unnamed), Cordelia, Ophelia, Bianca, Cressida, Desdemona, Juliet, Portia, Rosalind, Belinda, 1986U10 (still unnamed), Puck, Miranda, Ariel, Umbriel, Titania, Oberon, Caliban, and 1999U2 (still unnamed).

Answer 2

1. On Mercury, you would either freeze or roast. The highest surface temperature is 870° F (466° C), while the lowest temperature is –300 °F (–184 °C).

2. The average temperature on Saturn is
–300° F (–184° C).

3.
Jupiter has 63 moons. The four largest moons, Ganymede, Io, Europa, and Callisto, are called the Galilean moons because Galileo first saw them in 1610.

4. Neptune has 13 moons, the two largest are Triton and Nereid. Triton is made of rock and ice. Its surface is rich in water ice, dry ice, frozen carbon monoxide, methane, and nitrogen. Triton has cold geysers that spit nitrogen instead of the hot water that geysers on Earth release.


5. There are 47 moons orbiting Saturn. One of these bodies looks like the "Death Star" spaceship from Star Wars: Mimas has a large crater that covers one-third of the small moon. Enceladus, titan, pan, atlas, prometheus, pandora, epemetheus, janus, etc
