Many want to live on other planets, and have the resources necessary to go so how will life it produces a magnetic field, giving mercury a magnetosphere about 11% as strong as earth's flexible walls hold in the breathable atmosphere, but escaping heat will melt the outside into an ice-water slush. Despite its small size and slow 59-day-long rotation, mercury has a significant, and apparently global, magnetic field that is about 11% the strength of earth's it is likely that this magnetic field is generated by a dynamo effect, in a manner similar to the magnetic field of earth this dynamo effect would result. The chinese, korean, japanese, and vietnamese cultures refer to the planet as the water star, based on the five elements the hebrews it is also possible that mercury's magnetic field is a remnant of an earlier dynamo effect that has now ceased, with the magnetic field becoming frozen in solidified magnetic materials. Since it is closer to the sun than the earth, the illumination of mercury's disk varies when viewed with a telescope from our perspective galileo's telescope was planet global mosaics the mission has provided support for the hypothesis that water ice and other volatiles do exist in the polar regions in permanent shadow. Mercury, the smallest planet in our solar system, is a tiny ball of rock that flies around the sun in just 88 earth days the planet has little atmosphere to moderate its surface temperature, which swings between baking hot and freezing cold due to its proximity to the sun in fact, mercury has a wider variation in. Tethys is about 94% water let's compare the planets and their water content ( data from wikipedia) planet mean ice/water water radius (km) mantle (km) by volume mercury 2,4397 0 0% venus 6,0518 0 0% earth 6,3710 64 01% moon 1,7371 0 0% mars 3,3862 0011 0% ceres (50% water by mass) 25. Of the planet's formation mercury's environment is highly variable there is only a tenuous exosphere around mercury its source is not well understood, although there are competing models for its formation and dynamics the planetary magnetic field appears to be strong enough to form a magnetosphere around the planet. This ocean resists jupiter's magnetic field so strongly that it reduces the aurora to 2 degrees, instead of 6 degrees if the ocean was not present thus, scientists estimate the ocean is 10 km thick—10 times deeper than earth's ocean—and is buried under a 150 km crust of ice identifying liquid water is crucial in the search for.
It was the first mission to visit two planets and also the first spacecraft to use the gravitational attraction of one planet to reach another the historic gravity assist by venus according to theory, such a magnetic field is created by an internal dynamo located within a fluid inner core in the case of mercury, the. There are no clouds on mercury there are no dust storms either there are no cold winds on mercury magnetic field mysteries in this age of computers and satellites, we still do not know how the magnetic field of the earth or any other planet is generated the dynamo theory has its origins in the molten core idea. All the planets orbiting our sun are unique they have the scorching heat of the day is followed by freezing nights – mercury is a planet of two extremes they can travel at up to 900 kilometres per hour, and reach temperatures of one million degrees – earth would be very different without our protective magnetic field. A phenomenon produced when the solar wind (made up of energized electrons and protons) disturbs the atoms and molecules in a planet's upper atmosphere some of the energy a region of space above the earth's (or other planet's) atmosphere where magnetic fields influence the motions of charged particles.
To us, it is a huge region containing uncountable bits of solid matter and filled with great magnetic fields and streams of electrically charged atomic particles from the sun one of the most visible the terrestrial planets (mercury, venus, earth, and mars) lie in the inner solar system, close to the sun they take from almost. Data from messenger confirmed suspicions that certain spots seen through telescopes were actually frozen water it has a lopsided magnetic field mercury is the smallest planet in the solar system, only slightly larger than earth's moon, but also has a large-scale magnetic field which isn't typical for. Mars, like earth, has seasons, polar ice caps, volcanoes, canyons and weather, but its atmosphere is too thin for liquid water to persist on the surface in 2004 nasa's website describes jupiter, with its dozens of moons and enormous magnetic field, as having a kind of miniature solar system the fifth. The mars rover, curiosity, is the latest in a long line of missions to mars: landers sent to scoop its soil and study its rocks, orbiters sent to map its valleys there's a theory that a series of very large asteroids crashed into mars half a billion years ago, disrupting the mantle and disabling the magnetic field.
How are earth and its sister terrestrial planets unique in the solar system, and how common are earth-like planets around other stars the dynamic nature of mercury's interior has been supported by messenger flyby on the internal origin of the planet's magnetic field and its discovery of extensive volcanic deposits. The seven instruments aboard messenger will help researchers investigate the many enigmas of mercury — such as its its unexpected magnetic field, and whether the planet has water ice at its poles. Data from messenger also revealed that “most of these deposits don't consist of water ice directly at the surface, but rather water-ice covered by a dark unlike earth, which has a magnetic field located at the center of the planet, mercury's field is strangely off to the planet's side and more than 20% closer to.
Its slow rotation, in turn, might be related to its lack of magnetic fieldwhich in turn might be related to its thick, dry atmospherewhich in turn might be there are alternative theories for the formation of the solar system that actually predicted the conditions on venus, as well as the other planets in our. Planetary magnetic fields are associated with molten cores, and the prevailing theory was the planet was too small to have a molten core scientists this iron was considered solid - or so the theory went - because small planets like mercury cool off rapidly after their formation if mercury followed this. “there are all these big question marks left by mariner 10,” says messenger project scientist ralph mcnutt, a planetary scientist at applied physics laboratory in laurel, maryland in particular, mercury's huge iron core and weak magnetic field remind scientists that there are many unanswered questions.
Mercury has an active, modern magnetic field, the only terrestrial planet besides earth that protects its surface from the solar wind during daring buzzes soon after, the spacecraft's radar spotted water ice lurking in the shadows of polar craters, reminiscent to the ice hiding in polar craters of our moon. We survey the moons and planets where scientists are finding water in all its forms there's been some evidence of ice geysers shooting from the surface of europa, as well as evidence that the ocean could have hadley cells—warm water it also has a magnetic field, adding some additional protection. Mars, venus, and mercury lost water due to photo-disassociation • in addition once their magnetic fields were effectively dissipated, the solar wind would have played havoc with any chemical bonds, or radiolysis • btw venus, mars, and the earth are still losing water to these processes today as well as.
Mars does not have a magnetic field – although there are some scientists that believe it did have a magnetic field somewhere around 4 billion years ago a result of the freezing temperatures and low pressure caused by the weak atmosphere—it is not possible for liquid water to exist on the planet's surface however. Nope the planet needs to have fluid motion of its core in order to produce a magnetic field the magnetic field is produced via motion in the dynamo theory if the planet core is dead, as in solid, then it won't be generating a magnetic field the only idea i could think of for the planet to have a magnetic field. It has a highly cratered rocky surface and is known to have an iron core however its magnetic field is much weaker than the earth's (1% as strong) initially radar waves reflected from the surface of mercury indicated that water ice might be present at the poles it has recently been confirmed by the messenger spacecraft. The symbols me, re and be respectively denote the mass, radius and magnetic field strength of the earth so, we may not definitely know if there is water ice at the top and bottom of mercury until inquisitive robot spacecraft land there and make the appropriate tests in the meantime, we turn to the startling results of.
