Unser Sonnensystem - Der Merkur

Tlo na Merkuru je rahlo i razmrvljeno, kakvo nastaje pod udarima meteorita. Isti je proces odgovoran i za nastajanje pustinja na Zemlji. Merkur nema magme.

Merkur vrlo sporo rotira oko vlastite osi. Nekada se smatralo da je zbog plimnih sila sinkroniziran sa Suncem uvijek okrenut Suncu istom stranom.

Okrene se tri puta oko vlastite osi za vrijeme dva obilaska oko Sunca. Ovako spora rotacija Merkura ima kao posljedicu neke zanimljive efekte.

Care must be taken to ensure the instrument isn't pointed directly towards the Sun because of the risk for eye damage.

This method bypasses the limitation of twilight observing when the ecliptic is located at a low elevation e. Ground-based telescope observations of Mercury reveal only an illuminated partial disk with limited detail.

The Hubble Space Telescope cannot observe Mercury at all, due to safety procedures that prevent its pointing too close to the Sun.

Because the shift of 0. The earliest known recorded observations of Mercury are from the Mul. Apin tablets. These observations were most likely made by an Assyrian astronomer around the 14th century BC.

Apin tablets is transcribed as Udu. Ud "the jumping planet". The Babylonians called the planet Nabu after the messenger to the gods in their mythology.

The ancients knew Mercury by different names depending on whether it was an evening star or a morning star. By about BC, the ancient Greeks had realized the two stars were one.

The Greco - Egyptian [] astronomer Ptolemy wrote about the possibility of planetary transits across the face of the Sun in his work Planetary Hypotheses.

He suggested that no transits had been observed either because planets such as Mercury were too small to see, or because the transits were too infrequent.

It was associated with the direction north and the phase of water in the Five Phases system of metaphysics. In India, the Kerala school astronomer Nilakantha Somayaji in the 15th century developed a partially heliocentric planetary model in which Mercury orbits the Sun, which in turn orbits Earth, similar to the Tychonic system later proposed by Tycho Brahe in the late 16th century.

The first telescopic observations of Mercury were made by Galileo in the early 17th century. Although he observed phases when he looked at Venus, his telescope was not powerful enough to see the phases of Mercury.

In , Pierre Gassendi made the first telescopic observations of the transit of a planet across the Sun when he saw a transit of Mercury predicted by Johannes Kepler.

In , Giovanni Zupi used a telescope to discover that the planet had orbital phases similar to Venus and the Moon.

The observation demonstrated conclusively that Mercury orbited around the Sun. A rare event in astronomy is the passage of one planet in front of another occultation , as seen from Earth.

Mercury and Venus occult each other every few centuries, and the event of May 28, is the only one historically observed, having been seen by John Bevis at the Royal Greenwich Observatory.

The difficulties inherent in observing Mercury mean that it has been far less studied than the other planets. The effort to map the surface of Mercury was continued by Eugenios Antoniadi , who published a book in that included both maps and his own observations.

In June , Soviet scientists at the Institute of Radio-engineering and Electronics of the USSR Academy of Sciences , led by Vladimir Kotelnikov , became the first to bounce a radar signal off Mercury and receive it, starting radar observations of the planet.

Pettengill and Rolf B. Dyce, using the meter Arecibo Observatory radio telescope in Puerto Rico , showed conclusively that the planet's rotational period was about 59 days.

If Mercury were tidally locked, its dark face would be extremely cold, but measurements of radio emission revealed that it was much hotter than expected.

Astronomers were reluctant to drop the synchronous rotation theory and proposed alternative mechanisms such as powerful heat-distributing winds to explain the observations.

Italian astronomer Giuseppe Colombo noted that the rotation value was about two-thirds of Mercury's orbital period, and proposed that the planet's orbital and rotational periods were locked into a rather than a resonance.

Instead, the astronomers saw the same features during every second orbit and recorded them, but disregarded those seen in the meantime, when Mercury's other face was toward the Sun, because the orbital geometry meant that these observations were made under poor viewing conditions.

Ground-based optical observations did not shed much further light on Mercury, but radio astronomers using interferometry at microwave wavelengths, a technique that enables removal of the solar radiation, were able to discern physical and chemical characteristics of the subsurface layers to a depth of several meters.

Moreover, recent technological advances have led to improved ground-based observations. In , high-resolution lucky imaging observations were conducted by the Mount Wilson Observatory 1.

They provided the first views that resolved surface features on the parts of Mercury that were not imaged in the Mariner 10 mission.

Reaching Mercury from Earth poses significant technical challenges, because it orbits so much closer to the Sun than Earth.

Therefore, the spacecraft must make a large change in velocity delta-v to get to Mercury and then enter orbit, as compared to the delta-v required for other planetary missions.

The potential energy liberated by moving down the Sun's potential well becomes kinetic energy , requiring another large delta-v change to do anything other than rapidly pass by Mercury.

To land safely or enter a stable orbit the spacecraft would rely entirely on rocket motors. Aerobraking is ruled out because Mercury has a negligible atmosphere.

A trip to Mercury requires more rocket fuel than that required to escape the Solar System completely. As a result, only two space probes have visited it so far.

The second close approach was primarily used for imaging, but at the third approach, extensive magnetic data were obtained. The data revealed that the planet's magnetic field is much like Earth's, which deflects the solar wind around the planet.

For many years after the Mariner 10 encounters, the origin of Mercury's magnetic field remained the subject of several competing theories.

On March 24, , just eight days after its final close approach, Mariner 10 ran out of fuel. Because its orbit could no longer be accurately controlled, mission controllers instructed the probe to shut down.

It made a fly-by of Earth in August , and of Venus in October and June to place it onto the correct trajectory to reach an orbit around Mercury.

The probe successfully entered an elliptical orbit around the planet on March 18, The first orbital image of Mercury was obtained on March 29, The probe finished a one-year mapping mission, [] and then entered a one-year extended mission into The mission was designed to clear up six key issues: Mercury's high density, its geological history, the nature of its magnetic field , the structure of its core, whether it has ice at its poles, and where its tenuous atmosphere comes from.

To this end, the probe carried imaging devices that gathered much-higher-resolution images of much more of Mercury than Mariner 10 , assorted spectrometers to determine abundances of elements in the crust, and magnetometers and devices to measure velocities of charged particles.

Measurements of changes in the probe's orbital velocity were expected to be used to infer details of the planet's interior structure.

The European Space Agency and the Japanese Space Agency developed and launched a joint mission called BepiColombo , which will orbit Mercury with two probes: one to map the planet and the other to study its magnetosphere.

Both probes will operate for one terrestrial year. From Wikipedia, the free encyclopedia. For other uses, see Mercury disambiguation.

Merkur ist der am wenigsten erforschte innere Planet unseres Sonnensystems. Die Entstehung des Planeten Merkur Wissenschaftler gehen davon aus, dass der Planet Merkur vor rund 4,5 bis 4,0 Milliarden Jahren zusammen mit den Kennenlernen Seiten Planeten unseres Sonnensystems entstanden ist. April stürzte die Sonde dann auf die erdabgewandte Seite des Merkurs. Von der komplexen Erforschung des innersten Planeten erhoffen sich daher die Wissenschaftler auch neue Kaya Artemis Resort Casino über die Genese unseres eigenen blauen Planeten. Wie kann ich Merkur beobachten? Von diesen Partikeln und Meteoriten, die nicht in die Sonne fielen, sind demnach die meisten in den interstellaren Raum entwichen und 1 bis 2 Prozent auf die Venus sowie etwa 0,02 Prozent auf die Erde gelangt. Hingegen kann er gerade deshalb manchmal doppelsichtig werden, indem er mit freiem Auge sowohl in der hellen Morgen- wie in der hellen Abenddämmerung beobachtbar sein kann.
