MERCURY Â Â Â Â Â Â Â Â In Roman mythology atomic number 80 is courier of the gods, and son of the god Jupiter. quicksilver is the artificial satellite close set(predicate) to the solarize. Its distance from the solarise is come up 58 million km ( or so 36 million miles); its diameter is 4875 km (3030 miles); its volume and mass ar somewhat : that of the body suave; and its density is approximately bear on to that of the earth. mercury revolves about the sun in a distributor point of 88 days. Radar observations of the satellite show that its period of rotation is 58.7 days, or two-thirds of its period of revolution. The satellite, therefore, rotates unitary and a half eras during each revolution. Because its surface consists of rough, porous, dark-colored rock, hectogram is a poor reflector of sunlight. Mercury is the second smallest planet in the solar corpse and it has no known moons. Â Â Â Â Â Â Â Â spectroscopical studies indicate that only an super thin atmosphere, containing sodium and potassium. Collisions with inverse protoplanets early in the narration of the solar system may have stripped external lighter materials, thereby typography for Mercurys great density. The force of staidness on the planets surface is about one-third of that on earths surface. Â Â Â Â Â Â Â Â The hole 10 spacecraft passed Mercury twice in 1974 and at one time in 1975.
It sent moxie pictures of a moonlike, crater-pocked surface and account temperatures to be about 430° C (about 810° F) on the sunlit billet and about -180° C (about -290° F) on the dark side. Its atmosphere consists of sodium, helium, hydrogen, and oxygen. diddly-shit 10 also post horse a magnetic scene of action 1 percent that of the earth. variant that of the earths moon, the surface of Mercury is criss-crossed by long escarpments, dating perhaps from the period of contraction the planet experienced as it cooled both(prenominal) time early in its history.
