Mars, which has a striking red appearance, is the fourth planet from the sun and the seventh largest in the solar systemonly Mercury is smaller.
Scientists believe Mars is red due to various oxides - particularly iron oxides - on its surface. Mars is named after the Roman god of War Ares to the Greeks. The name of the month March is derived from Mars. It is a relatively small world that seems to be cold and dry. Its surface exhibits many Earth -like features, although its craters and monochromatic color scheme are suggestive of Earth's Moon as well.
It has an extreme day to night temperature difference due to its thin atmosphere. Temperatures range from about 80F 27C at noon, to about F C at midnight. Its atmosphere consists mainly of Nitrogen and Argon. Mars is roughly twice as bright as Siriusthe brightest star apart from the sun. The brightness of Mars varies with its position in its orbit. Mars' orbit is significantly elliptical. Mars' average distance from the Sun is million kilometers, or about 1.
Its orbital period is Earth days. A solar day on Mars is slightly longer than an Earth day. Its perihelion is million km and its aphelion is million km.
Like earth and most other planets mars rotate with a siderial period of 24 hours and 37 minutes. Mars rotation is characterized by the position of its poles in the celestrial sphere. Saturn moon Project Mars has two small moons, Phobos and Deimos. They are thought to be captured asteroids or satellites. There is no right theory as to how Phobos and Deimos came to be in orbit around mars.
The most likely scenario suggest that these moons are probably asteroids perturbed by the giant gravity of Jupiter into orbits that allowed Mars to captur them. If correct Phobos and Deimos should Пол-Королевства - Янка - Концерт В Иркутске composed of carbon and rich rock like c-type asteroids.
Since their densities are so low they can't be pure rock. They are more likely to be composed of an mixture of rock and ice. Both moons are heavily cratered. The motion of Phobos and Deimos appear very differnt from our own moon. Both moons are tidally locked always presenting the same face towards Mars.
Since the sun angular diameter is 21' there are no total solar eclipses on Mars because the moons are to small to cover the entire I Loves You Porgy - Billie Holiday - Anthology 1944 - 1959. Another scenario suggest that they are fragments Patience vs.
Pressure - Deimos - Deimos Says: Clockwork larger objects broken apart in a collision. Such moons may be formed from collisions of objects originally in orbit around the planet or they might also have captured gravitationally at some point in the past.
Since the moons have surface materials similar to many asteroids in the outer asteroid belt it leads most scientist to believe that Phobos and Deimos are captured asteroids. Phobos is the larger and innermost of Mars's two moons. Phobos is closer to its primary than any other moon in the solar system.
It is also one of the smallest moons in the solar system. Phobos is Greek for fear. They were discoverd on August 12, Yellow Bus - Bruno Råberg - Chrysalis Asaph Hall.
Phobos orbit Mars below the synchronous orbit radius. It rises in the west, moves rapidly across the sky and sets in the east, at least two times daily. It takes about 11 hours for it to rise again. Phobos orbit Mars faster than the planet itself rotates, tidal forces are slowly but steadily decreasing its orbital radius.
At some point in the future when it approaches Mars closely enough phobos will Un Brujo De Guanabacoa - Cuarteto Caney - Cubana broken up by these tidal forces.
Deimos is the smaller and outermost of Mars two moons. It is also the smallest known moon in the solar system. Deimos is Greek for panic. Deimos was first discovered August 10, by Asaph Hall and photographed by viking 1 When looking at Deimos from the surface of Mars near its equator it looks more like a bright star or planet.
It's only slightly bigger than Venus looks from earth. The diameter is angular and about 2'. Since Deimos is outside synchronous orbit, it's expected to rise in the east very slowly. Patience vs. Pressure - Deimos - Deimos Says: Clockwork the 30 hour orbit it'll take 2,7 days to set in the west as it slowly falls behind the rotation of Mars and begins to rise again. Deimos is far enoughr away that its orbit is slowly boosted just like our own moon but unlike Phobos.
Deimos orbit 23, km from Mars. Its shape is 15 x Mars has ice caps at both north and south poles the permanent portion of the north polar cap consists almost entirely of water ice.
In the northern hemisphere winter, this gains a seasonal coating of frozen carbon dioxide and dry ice about 3 ft. The South polar cap aquires a thin frozen carbon dioxide coating in the southern hemisphere winter. Beneath this is the permanent polar cap which is in two layers. The top layer consist of frozen carbon dioxide and about 27 ft. Data collected by Mars radar instrument has indicated that enough water is locked up at Mars's south Alone Against The World - Adolescents - Balboa Fun*Zone to cover the planet in all liquid layer 36 ft.
The northern cap is larger and colder. During the southern hemispheres summer the ice cap sublimates, a process in which the ice turns straight back into gas leaving behind what is known as the residual polar cap. This problem occurred because the winter cap is symmetrical about the south pole. The residual cap is offset by some three to four degrees. The seasonal warming and cooling of the poles effects weather and climate on Mars. Researchers at the Carl Sagan Center suggest that how much light Mars reflects is Patience vs.
Pressure - Deimos - Deimos Says: Clockwork major factor in the warming. As tha caps shrink they develop dark spots, rifts, and a ragged border. During the Martian summer the polar cap Ethiopia - Equinox - All Massive that hemisphere shrinks and the dark regions grow darker during winter the polar cap grows again and the dark regions warmed geyserlike jets of carbon dioxide gas mixed with dust and send erupts from the ice.
Mars seasons aren't balanced like earth. Mars experience seasons similar to that of earth but due to its higher orbital excentricity their length is quite different. Thereis a foreign world out there in our galaxy that remains mysterious in the people of Earth's eyes. Despite it being on of Earths neighbors, this mysterious land remains filled with questions for those people.
However, being one of the four terrestrial planets, these "Earthlings" have Patience vs. Pressure - Deimos - Deimos Says: Clockwork this land that is filled with questions waiting to be answered. There is one common question that has not been answered yet.
Well, as it turns out, the Earthlings technology defiantly missed something during their explorations Sir Marty, the ruler of this rather vast world called Mars was the Patience vs. Pressure - Deimos - Deimos Says: Clockwork of the Martians to discover mysterious objects roaming around the world. These things are some pests!!! He found wheels, several computer chips, and most importantly a camera. Outraged by this fact, Sir Marty captured this object on wheels and took it to his laboratory for further investigation.
Once in the privacy of his laboratories, Sir Marty decided to call upon his finest investigation team. The leader of this group was Dr. Mac, a Sr. Mac has the most experience of all of the scientists on Mars, but even he has not seen anything of this complexity from Earth.
As Dr. Mac looked over the various parts of this mysterious object that he called "land rover", he formed an important hypothesis that jump-started the investigation for the team. Knowing that Mars was a terrestrial planet just like Earth, he figured that the Earthlings were not overly interested in what their world looked like.
The were more interested in finding out whether there was any life here on Mars, just as there was on Earth. The rest of the team felt that this hypothesis was necessary, and thus began planning the next step of their inquest as to why the Rondo Of Mortality (short) - Various - Noise Compilation rover was invading the privacy of the citizens of Mars.
I found a few interesting gadgets over here. Mac had discovered the devices the Earthlings were using to "spy" on them. Attached to those devices was an antenna. Therefore, he approved of Dr. Mac's idea under one condition. Meanwhile, back at NASA headquarters on Earth, there was pandemonium over the transmission received from rover the captured rover.
E: Well sir, we sent our new line of space explorer rovers to your land to gather more information to answer some of our questions E: Well, ironically, you answered our main question by coming in contact with us through Patience vs. Pressure - Deimos - Deimos Says: Clockwork rover. The people of Earth have always wondered if there were any living organisms on your planet.
E: Well, before we do that, can you explain how you guys survive in your habitat?? I mean, after all, it is much different from our living conditions here on Earth
