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

surface on Saturn reach -275 degrees Fahrenheit. Saturn has about 47 moons or more that are made of rock and ice. It is said that meteors probably hit Saturn ’s moons. The largest of Saturn ’s moons is named Titan. Titan is larger than the planet Mercury. Titan is the second largest moon in our Solar System. Titan ’s atmosphere is orange. We cannot see the surface of Titan because of the thick atmosphere. The smallest moon on Saturn is called Pan. It is only 12 miles wide. About 35 of Saturn ’s moons

between Foci 5‚083‚000 km 5. The eccentricity of Earth’s orbit is less than the eccentricity of the four ellipses I drew. 6. The Earth’s orbit is more round. 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-

Hg2+ Refer(1) Why is detection of Hg2+ important?? Mercury contamination poses severe health risks. It can enter into environment through natural as well as human activities. Once it enters marine environment‚ bacteria convert inorganic mercury to methyl mercury which enters food chain and is accumulated in large edible fish. Its imbalance can lead to neurological disorders and can cause Minamata disease. Procedure to detect Hg2+ 1. MS1 (Mercury Sensor 1)‚ a water soluble‚ fluorescein based sensor

but back to learning about the universe. It is true that we only have 8 planets. However‚ the solar system is comprised of 100s of different miscellaneous worlds which are very adequate. Some of the moons and minor planets are more massive than Mercury. Some have active volcanoes and oceans of liquid methane which is quite hazardous and random. Almost every planet and some moons have an atmosphere. If we had lost our transparent atmosphere though some may
