planet-like moon‚ Titan has a diameter 50% larger than Earth’s natural satellite‚ the Moon‚ and is 80% more massive. It is the second-largest moon in the Solar System‚ after Jupiter’s moon Ganymede‚ and is larger by volume than the smallest planet‚ Mercury‚ although only 40% as massive. Discovered in 1655 by the Dutch astronomer Christiaan Huygens Titan was the first known moon of Saturn‚ and the fifth known satellite of another planet. Titan is primarily composed of water ice and rocky material.

motion. Ptolemy’s model‚ in part‚ sought to explain this behavior. The inferior planets were always observed to be near the sun‚ appearing only shortly before sunrise or shortly after sunset. To accommodate this‚ Ptolemy’s model fixed the motion of Mercury and Venus so that the line from the equant point to the center of the epicycle was always parallel to the earth-sun line. 17.

Effect of Iodine on mercury concentrations in dental-unit wastewater John Michael Panganiban and Ian Jasper Ocampo Objective: This study was undertaken to determine whether iodine used to control bacteria in dental unit wastewater could increase mercury concentrations in dental wastewater. Introduction: Two of the major concerns in dentistry are biofilm in dental unit waterlines and the contamination of dental unit wastewater with mercury. Biofilms are microscopic communities that consist

retinue of objects that orbit the Sun‚ most of the mass is contained within eight (8) relatively solitary planets whose orbits are almost circular and contained within a nearly-flat disc called the ecliptic plane. The four smaller inner planets; Mercury‚ Venus‚ Earth and Mars‚ also called the terrestrial planets‚ are primarily composed of rock and metal. The four outer planets‚ Jupiter‚ Saturn‚ Uranus and Neptune‚ also called the gas giants‚ are composed largely of hydrogen and helium and are far

Titan‚ is the only moon in the Solar System to possess an atmosphere. FACT NINE Saturn has such a low density (meaning that its particles are far apart) that‚ if there was an ocean big enough‚ Saturn would float on it. In comparison‚ Earth and Mercury would sink to the bottom quickest. FACT TEN A year on Saturn would take almost thirty Earth years. However‚ a day on Saturn is about 10 and a half

Planetary Study Guide Mercury * As seen from Earth: * Orbital period of 88 days; rotation to orbit is a 3:2 ratio * Distance from Sun: 0.31 AU to 0.46 AU from the Sun * Eccentric orbit: close and far away (perihelion and aphelion) * 7 percent to the ecliptic * Visible by the naked eye just before sunrise or just after sunset (when the Sun’s light is blotted out) * Never far from the Sun * As a physical body: * Small (about 0.055 Earth’s

I know this because the lesser the number‚ the more rounder the circle would be. 7. Mercury has an eccentricity most similar to the ellipses I drew. 8. If I was to draw the Earth’s orbit‚ a star would be one of the foci. 9. Upon completion of this lab exercise‚ I was able to: 1- Define the words: eccentricity‚ ellipse‚ and foci. 2-

rotation‚ solid surfaces‚ no rings‚ and few satellites. These planets include Mercury‚ Venus‚ Earth‚ and Mars. On the other hand‚ the jovian planets are composed primarily of hydrogen and helium. They generally have low densities‚ rapid rotation‚ deep atmospheres‚ rings‚ and numerous satellites. These planets include Jupiter‚ Saturn‚ Uranus‚ and Neptune. The closest terrestrial planet to the sun is Mercury. Mercury is relatively small‚ and technically the eighth largest of all the planets.
