As such, it is a very unique planet which is difficult but worth studying. There are only 58 million Kilometers separating the sun from Mercury (“NASA” 1) thus making the study of Mercury difficult for scholars. Nevertheless, a radar imaging from the Earth in the 1960s helped scientists to study Mercury. As such, scientists confirm that Mercury has a radius of 2,439.7 km, a volume of 60,827,208,742 km3, and a total mass of about 330,104,000,000,000,000,000,000 kg (“NASA” 1). Furthermore, with a density of 5.4 grams per cubic centimeter, Mercury is very dense compared to other planets in the solar system (“Space Facts” 1). Although Mercury revolves around the sun at the fastest speed, it seemingly rotates around its axis at a very slow speed where it takes about 1 Mercury day or 59 Earth days to make a complete spin (“NASA” 1). Indeed, mercury takes about 88 Earth days or 1 Mercury year to revolve around the sun (“NASA” 1)....
More so, the thin exosphere ensures the prevention of wind erosion on the surface of Mercury and that friction does not cause the meteorites to burn (“National Geographic Society” 1). The composition of the thin exosphere entails different levels of potassium, oxygen, neon, argon, sodium, carbon dioxide, hydrogen (H2), nitrogen, helium (He), and krypton (“NASA” 1). The core of Mercury has the highest iron content higher iron content the Solar System (“National Geographic Society” 1) where its metallic core measures about 2200 to 2,400 miles in width, 42% of its volume (“Space Facts” 1), and about 75 percent of the its diameter. With a magnetic field in the solar wind, Mercury is very active and its charged particles normally stream from the sun and touch the planet’s magnetic field thereby creating a powerful magnetic tornado (“Science Daily” 1). The magnetic tornado transmits the hot plasma of the solar wind to the surface of Mercury. Scientists established that the iron core of Mercury cools and contacts to wrinkle the surface of the planet. They further named the wrinkles as Lobate Scarps, which extend to hundreds of miles in length (“Space Facts” 1). Ideally, there have been various theories explaining how Mercury formed which relate to the physical removal of silicates or the differences in the composition material. One of the theories attributes the formation of Mercury to an impact that shrunk the size and mass of the planet. The shrinking occurred as the planet cooled (“National Geographic Society” 1) and led to the crumpling and formation of cliffs on the surface of Mercury. Indeed, scientists believe that the planetesimal reduced ...Download file to see next pages Read More

Planet Earth

...Planet Earth: Disc There are cycles to almost everything in nature and this is shown in the first DVD of the Planet Earth series; "From Pole to Pole/ Mountains/ Fresh Water". The seasons are a cycle that is brought up continuously throughout every section, whether it is two seasons or four depends on the location. Places that reside along the equator experience only two seasons, one wet and one dry, because they get an immense amount of direct sun exposure. This is because of the way the Earth is positioned; this tilt of the earth's axis is also what is directly responsible for the four seasons of the most northern and the most southern climates. Due to the fact that all things do depend on the sun as it represents a new beginning...

Erosion on the Earths Moon, Venus and Mercury

...Erosion on the Earth’s Moon, Venus and Mercury There is very less erosion on the planet Venus's surface. Some scientists claim that the planet is not as old as other planets, thereby offering less time for erosion to occur. "A paucity of surface features usually indicates a young surface, not an old one, because there would be less time for cratering to occur." (Tim, 1994 cited in, 2003). However the cold temperature of the Venus compliments the concept of it being young. Had the planet been a new one, it would have been far hotter than what it is now because of the tremendous amount of energy released as a result of its birth. Its solid surface and thick crust also support this idea. The right reason why there is so...

Absorption Features in an Extrasolar Planet Atmosphere

...THE SEARCH FOR EXOPLANETS With respect to the search for exoplanets astronomers have made certain generalizations based both on factual observation, as well as limitations of instrumentality. An important strategy for planet detection must be the location of optimal configuration. At present, astronomers have uncovered several super earths, so named due to the superiority of size and mass with respect to our own planet – but those that we have presently discovered tended to orbit very close to their stars. In fact, all the super earths presently known to astronomers exist within a very limited, close range that is consistent between divergent star systems. This may not apply that no terrestrial planets, Earth like or larger than Earth...
