Eight Things Revolving the Sun

Eight Things Revolving the Sun

        The earth is a member of the sun’s family. The sun’s family is called solar system. The earth is a planet. There are other planets in the solar system. The solar system is made up of the sun and all the objects that move around it.

        There are eight known planets which circle around the sun in elliptical orbits. They are group into two: the inner planets and the outer planets. The period of the revolution around the sun varies with each planet: the nearer the planets having the shorter periods. The planets also rotate there axes, as does the earth.

  The Eight Planets

*The Inner Planets:

Mercury

        The closest to the sun and the fastest of the eight planets to revolve around the sun.  It can travel 46km/sec. that is why the planet is named after a messenger of the Roman God who had wings on its feet. It spins on its axis once in every 59 days and revolves around the sun in 88 days.

Venus          

        Known as the “Pressure Cooker Planet” because of its very high atmospheric temperature. It is the brightest celestial body in our sky after the moon and the sun. It has an atmosphere made up of mainly carbon dioxide and sulfuric acid gas with a very small amount of oxygen.

Earth  

        The only planet known that life is existent. The planets where living things dwell- the animals and the humans. The atmosphere has enough oxygen sustainable to life on earth. It rotates to its axis in every 24 hours and revolves around the sun in every 365 and ¼ days. It has only one satellite or moon that orbits around the earth.

Mars 

        It is a lifeless dessert dry planet. Its thin atmosphere of mostly carbon dioxide is over 100 times drier than the earth. Aside from earth, it is the only planet which has snow. It is made up of chiefly carbon dioxide and has no ozone in its atmosphere to react from radiation. Also known as the “Red Planet” because of iron oxide present in the soil.

*The Outer Planets: 

Jupiter

        The largest planet in the solar system. It rotates 9hrs. and 50mins., making it as the fastest rotating planet. It has 16 satellites, which the two are roughly equal to the size of the earth’s moon. The rings are so thin which make them essentially transparent. Its ice and ammonia atmosphere contains one of the Jupiter’s mysteries: “The Red Spot”.

Saturn 

        The second largest planet, consist of a solid core surrounded by an icy layer and thick atmosphere of gases, the rings is composed of billions small particles of grain of sand. It has magnificent system of rings made up of countless ice-coated particles.

Uranus

        A greenish-blue gas planet. Has a series of rings around it but is believe to be relatively young. There are 11 rings in various sizes and densities. It has 15 moons, which its gravitational force helps maintain the rings of the planet.

Neptune

        A bluish planet, which gives off more energy that it receives from the sun. It is named after the Roman God of the sea. Neptune and Uranus are like twins, being similar in size; they both appear as pale green due to it has two tremendous amount of methane gas stretch all around its surface. Neptune possesses a barely detachable system of four rings of very dark matter. The outer ring is clumped into ring of different densities.
