Asteroids Effect On Mars

On Earth we have one moon to look at during the night. Can you imagine looking at 50 or 60 moons at night? If we lived on Jupiter, that’s what we would see! Jupiter has 50 definite moons. There are 17 moons scientists are still examining to make sure that they are moons. Some are smaller than 1.5 miles in diameter! Jupiter’s four largest moons, and four first discovered, are known as the Galilean moons, named after their discoverer Galileo Galilee in 1610.

and is not fully understood. One of Saturn’s moon is Titan .Made up of a rock like core

Jupiter’s four largest moons were found by Galileo Galilee. Those moons are known as the Galilean satellites. Jupiter has over 67 moons, most have been named but some still remain. (Chown, M.C 2011 Solar System, Touch Press 115-137). Jupiter also has rings. Like all the other gas giants Jupiter also has rings but unlike the other planets with rings, Jupiter’s are pretty much invisible, they are the very dark. It is impossible to see Jupiter’s rings with a pair of binoculars. In fact, no one knew that Jupiter has rings until they were first seen with a very powerful telescope in 1979. Jupiter’s magnetic field is about 20,000 times stronger than Earth’s magnetic field and Jupiter’s magnetic field ranges farther than Saturn and Jupiter’s gravity is interferes with Saturn’s orbit around the sun. Jupiter’s magnetosphere revolves with Jupiter every 10 hours. The space inside the magnetosphere is filled with solar winds and its own subatomic particles. Some are placed in the magnetosphere by the volcanoes on Io (one of Jupiter’s moons) which create a doughnut-shaped ring of Sulphur and sodium around

There are a lot of moon but the four main ones or biggest ones are Io, Callisto, Europa, and Ganymede. Io is very hot and has a lot of volcanos and lava. All of the volcanos cause the surface of Io to be covered in sulfur which is ash from the volcanoes. Jupiter's gravitational pull is so strong that it causes Io’s solid surface to to rise and drop, like a wave, from 300-100 feet at a time! Europa’s surface is the opposite. It has ice and is might be all water. It is even thought to have twice as much water as earth. Europa is thought to actually have life under the ice but no one has ever been there to see. Callisto is very heavily cratered. It is thought to be one of the first of Jupiter's moons. It is just like our moon but bigger. There isn't much of anything out of the ordinary about it. Ganymede is very crazy because it has its own gravitational pull unlike moons. It almost fell for a dwarf planet if it didn't orbit Jupiter. This makes it the largest moon in our solar system.

Saturn's largest moon is Titan, is a bit bigger than the planet Mercury. Titan is the second largest moon. Saturn has a light orange look with white and gray rings. These rings are made up of ice, rocks, and dust. Saturn's rings are more than 270,000,000 kilometers wide but not even 1 kilometer thick, it also has more than 30 layers of the ring. It is made up of 94% hydrogen, 6% helium. Which means it is mostly gas. Its temperature is around minus 178 degrees Celsius.

Jupiter, Saturn, Uranus, and Neptune collectively make up the group known as the Jovian planets. The general structure of these planets are the opposite of the terrestrial planets. The Jovian planets have a small and dense core surrounded by huge layers of gas rather than having thin atmospheres around large and rocky bodies. These planets are made up almost entirely of hydrogen and helium and do not have solid surfaces. All four Jovian planets are surrounded by a set of rings. These rings consist of rock, ice and dust particles that rage from microscopically small particles to the size of a giant houses, cars etc. There is plenty information about what is currently known and theorized about the formation of the rings, the different ring systems, and why terrestrial planets do not have natural rings.

Apollo asteroids are small celestial objects in comparison with other planets but are large enough to cause significant damage to earth and organisms living in its environment. Present 30 known asteroids are with diameters ranging from 0.2-8km. Orbital perturbations by the planets might cause asteroids to collide with earth. The probability of an asteroid colliding with the earth is well defined and certainly non-zero. Earth and the asteroid might meet the intersection point where the asteroid would be able to strike our planet. An impact from such asteroid would create an enormous crater being 20 times the size of the celestial body itself. After impacting the earth's lithosphere it would eject the mass from the crater about 100 times the

Saturn is one of the most interesting planets in the solar system. It is the sixth planet in the solar system, and is most famous for its stunning array of rings. It is a very easy planet to pick out in the sky because it is one of the brightest lights in the shy. It also has a very faint greenish color that makes it stand out from the rest of the objects in the sky (“Astronomy for Kids”). Saturn is the second largest planet in the solar system, Jupiter being the only planet that is bigger. It also has at least eighteen moons, more than any other planet in the solar system. There have been three voyages to this extraordinary planet, and one is still in process today. The Pioneer II traveled to Saturn in September of 1979,

When addressing the concern of an asteroid impacting the Earth, it should be noted that the probability of a continent-destroying asteroid is slim to none in the near future. It should also be addressed that approximately ten asteroids enter Earth's atmosphere per year, each being about the size of a fridge, but are burned up quickly and would not be big enough to heavily crater or harm anything on the surface. In the past 1000 years, there also have been no record of a human dying due to meteorite collisions. Though collisions are seemingly rare, it is still important for astronomers to observe any celestial objects moving towards Earth that may be potentially dangerous. For example, Apophis is an asteroid traveling a path towards Earth. The asteroid is large enough to wreck the surface of Earth, but because of the observations made by astronomers, it is highly likely that a mission can be conducted to be deflected

The rings around Jupiter appear to resemble the shape of a crown. These crown - shaped rings are composed of ice and rock debris. This debris is collected from things such as when meteorites hit one of the moons of Saturn, which the gravity coming from the planet tends to pull debris towards it from all of its moons. Sometimes, as a comet travels near the planet, the rings will collect more debris.

But the rings are remarkably skinny, expected to be less than a kilometer thick. The rings are split into categories, Ring A, Ring B, Ring C, Ring D, Ring E, Ring F and Ring G, adding 7 in all. The rings are not solid but fairly are made up of particles of ice, dust and rocks. The rings are held in place around Saturn by the moons that also orbit this large planet. The gravity of these moons also causes the holes that are seen in between the

Since they do fall to earth a lot, “asteroids typically top the list of extraterrestrial objects that could hit Earth” (Hernandez, 2012, p. 1). This is true but an asteroid would have to be pretty big in order for it to cause mass destruction.

However, the arriving of rovers on Mars shows that Mars is a cold, desiccated and lifeless planet, which is not capable for creatures to exist. Comparing to Earth, Mars has a similar weight, size, obit and gravity. However, the surface features are greatly different. According to the article “Mars Compared to Earth” by Matt Williams, Earth is covered mostly by liquid water. By contrast, the surface of Mars is dry, dusty, and covered in dirt that is rich iron oxide.

Saturn is considered to be the second largest planet within our solar system. It consists of mostly hydrogen and helium. Saturn's rings are believed to be holding multiple fragments of comets, asteroids and even shattered moons that had broken up before entering the planet. The particles in the rings compare in size from a tiny dust-sized grains to chuck's almost the size of mountains. The ring system reaches about 175,000 miles. The ring system includes what can only be considered "braided rings", ringlets, and "spokes" which are dark features that form within the rings. The rings generally circle the planet at different rates. The shepherd satellites affects some planetary rings in different ways. In the case of Saturn, this planets satellites,

When one contemplates Saturn, they instantaneously consider its notorious rings. Saturn’s rings should produce reflection upon the qualities of restriction, boundaries, and limitations; similarly, these are the attributes that Saturn imposes upon people. In addition, Saturn takes a plodding, relentless pace around the Sun; consequentially, Saturn is viewed as Father Time in mythology. In like manner, Saturn slowly and steadily teaches people lessons of practicality, compliance, responsibility, and a realistic view of their capabilities.
