Mercury

MERCURY In Roman mythology [|Mercury] is the god of commerce, travel and thievery, the Roman counterpart of the Greek god [|Hermes], the messenger of the Gods. The planet probably received this name because it moves so quickly across the sky.

GREEK GOD HERMES []  The greek god Hermes, known in Rome as Mercury. He was the messenger of the gods and he was very fast. (His boots had wings on them). The Planet Mercury was named after Hermes because it is the fastest orbiting planet in our solar system.

Mercury is the innermost and smallest [|planet] in the [|Solar System], (5.427 g/cm³). It is a little bigger than the Earth’s moon. The inner planets. From left to right: [|Mercury], [|Venus] , [|Earth] , and [|Mars]

Mercury is [|orbiting] the [|Sun] once every 87.969 Earth days. The orbit of Mercury has the highest [|eccentricity] of all the Solar System planets, and it has the smallest [|axial tilt]. It has three rotations about its axis for every two orbits. After one orbit, Mercury has rotated 1.5 times, so after two complete orbits the same hemisphere is again illuminated. The [|perihelion] of Mercury's orbit [|precesses] around the Sun at an excess of 43 [|arcseconds] per century, [|a phenomenon that was explained in the 20th century] by [|Albert Einstein] 's [|General Theory of Relativity]

The [|surface] of Mercury has numerous interesting features, including a variety of craters, ridges, and terrains ranging from heavily cratered to nearly crater free. also has the second largest density in the Solar System. It is only slightly less denser than Earth. (3.30e23 kg) 5.5% of Earth's mass. Mercury is dry, extremely hot and almost airless. It has a weak atmosphere it is too small for its gravity to retain any significant atmosphere over long periods of time. The weak atmosphere contains hydrogen, helium, oxygen, sodium, calcium and potassium similar in appearance to the [|Moon] The interior of Mercury is a metallic core, an intermediate rocky layer, and a thin brittle crust. The composition of Mercury is probably high in iron, although [|surface features] indicate that volcanic activity once existed at the surface.

Mercury orbits the __ [|Sun] __ closer than any other planet in the Solar System. The side of Mercury facing the Sun can reach 700 Kelvin, which is equivalent to a [|temperature] of 800 degrees fahrenheit. It dips down to 100 Kelvin. 100 kelvin = -279.67° Fahrenheit. It is the innermost planet and is one of the 5 planets visible with the unaided eye. .

AMERICAN SPACE PROBES TO VISIT MERCURY

[|Mariner 10 probe] is the first probe that visited Mercury in 1973. (Flyby Mission)

The [|messenger] is the second to visit Mercury (began 2004). It was Designed to study the characteristics and environment of Mercury from orbit. On March 29, 2011, NASA's [|MESSENGER] spacecraft began sending its first close-up images of planet Mercury from orbit (MESSENGER [|news release] and [|feature release] ; and [|Kenneth Chang, //New York Times//, March 30, 2011] ). After three flybys, MESSENGER inserted itself into orbit around Sol's innermost planet beginning March 18, 2011, at 12:35 AM [|UTC] (March 17, 2011, at 8:35 PM [|EDT] ). []

The surface of Mercury has numerous interesting features, including a variety of craters, ridges, and terrains ranging from heavily cratered to nearly crater free. These features, and their location across the known planet surface, helps us to understand the [|evolution] of the planet.

A **planet** is a [|celestial body] [|orbiting] a [|star] or [|stellar remnant] that is massive enough to be rounded by its own [|gravity], is not massive enough to cause [|thermonuclear fusion] , and has [|cleared its neighbouring region] of [|planetesimals]. The term //planet// is ancient, with ties to [|history], [|science] , [|mythology] , and [|religion]. The planets were originally seen by many early cultures as divine, or as emissaries of the [|gods]. As scientific knowledge advanced, human perception of the planets changed, incorporating a number of disparate objects. In 2006, the [|International Astronomical Union] officially adopted a resolution [|defining planets] within the [|Solar System]. This definition has been both praised and criticized, and remains disputed by some scientists.

[] Title: The Planet Mercury Audience: the audience that is being targeted are people of all ages.

The Planet Mercury is the closest planet to our sun and is the smallest planet in the solar system. Mercury has no moons that orbit it nor does it have any natural satellites and no substantial atmosphere. Mercury takes about 58 days to rotate, and is 4,878km (3,032 miles) at its equator, which is about two-fifths of Earth's diameter. According to the Earths radar there has been some water that craters at Mercury's poles contain water ice. Like other terrestrial planets Mercury is composed mostly of rock.

Do to Mercury's close orbit to the sun the weather on this planet can be very extreme and dangerous. The maximum temperature on Mercury can reach up to 801 degrees F, without much of an atmosphere to attract the heat the low temperatures on Mercury can drop as low as -279 degrees F. When your standing on the hot surface of Mercury you can see the sun three times as larger than if you were to stand on the Earths surface. Another fact that is interesting is that Mercury's surface resembles that of the Earths moon.

Title all about Astronomy: Mercury Audience: the audience that is being targeted is the young teen audience who wants to know about Mercury.

The gravity on Mercury is 38% of the gravity on Earth, for example, if you weigh 100 pounds on Earth on Mercury you would only weigh about 38 pounds. Mercury's mass is really low if it would to be calculated on a scale it would take 20 Mercury's to weigh as much as the Earth. Mercury is the closet planet to the sun and the fastest moving planet in the solar system. There are no seasons on Mercury because the tilt on Mercury is directly perpendicular to its motion therefore there are no seasons.

 Title: Interesting Facts about MercuryAudience: the audience that is being targeted are teenagers and adults. Did you know that half of Mercury hasn't even been discovered yet? It was not until NASA's messenger aircraft did a flyby over Mercury in 2008. The Mariner 10 spacecraft took some photographs of parts of Mercury in 1974-75, but it never took pictures of the other side of the planet. Mercury's orbit helped out prove Albert Einstein's theory of relativity. Astronomers today use Einstein's calculations to predict the movement of Mercury through out the solar system, even though today the astronomers have more accurate calculations they decided to use Einstein's calculations instead .
