system formed about 4.6 billion years ago. 4. The four planets closest to the Sun - Mercury‚ Venus‚ Earth‚ and Mars - are called the terrestrial planets because they have solid‚ rocky surfaces. 5. Two of the outer planets beyond the orbit of Mars - Jupiter and Saturn - are known as gas giants; the more distant Uranus and Neptune are called ice giants. 6. Most of the known dwarf planets exist in an icy zone beyond Neptune called the Kuiper Belt‚ which is also the point of origin for many comets. 7

The asteroid belt is the region of the Solar System located roughly between the orbits of the planets Mars and Jupiter. It is occupied by numerous irregularly shaped bodies called asteroids or minor planets. The asteroid belt region is also termed the main asteroid belt or main belt because there are other asteroids in the solar system such as near-Earth asteroids and trojan asteroids. More than half the mass of the main belt is contained in the four largest objects: Ceres‚ 4 Vesta‚ 2 Pallas‚ and

rock bodies orbiting the sun. It was once believed that the asteroids were the remains of a planet that was destroyed many years ago. This theory can not be proven true because‚ the location of the asteroid belt could not be home to a planet due to Jupiters gravitational pull. It is now believed that asteroid are planetesimals broken down by collision‚ also known as a minute planet. A planetesimal is a body that could or did come together with many others under gravitation to form a planet. This theory

day’s length is almost the same as Earth’s. Jupiter is the next planet. It is the largest planet of all the planets. Its mass is three hundred and eighteen times bigger than Earth. It travels very slowly‚ and takes 12 Earth years to rotate once around the sun. Jupiter also has a very low density. In fact‚ it is only about ¼ of Earth’s density. This is because Jupiter is made up of very light elements‚ such as hydrogen‚ and helium. Saturn follows Jupiter in the line up of planets. It can be identified

Galileo Galilei is one of the most well known and popular scientist beside Albert Einstein. At the very basis of what he did‚ Galileo changed how people looked at the world around them especially the solar system. Eventually the church held a trial against Galileo on the act of heresy and attack on the Aristotelian idea of the universe as the church and many others believed that the earth was at the center of the solar system not the sun. He also had many inventions which helped future scientists

the project completely. Voyager 1 had a chance to fly pass Pluto. Scientist instead chose to study Jupiter and Saturn’s moons. Flying past both moons io and triton brought voyager 1 so close to Jupiter causing the probe to gain so much speed it could not be redirected to Pluto as it flew pass Saturn. Voyager 2 was designed to follow the same flight path as voyager 1 this time the journey passed Jupiter was a lot smoother. Unfortunately‚ Neptune was not in the right position for voyager 2 to be directed

The depiction of Jupiter‚ also known as Zeus‚ takes on many different forms depending on the author and timeframe in which we are examining him. Throughout the article “Jupiter in Ovid’s Metamorphoses” Charles Segal juxtaposes Ovid’s characteristics of Jupiter amongst that of other prominent poets of comparative eras‚ Homer and Virgil. Ovid’s Jupiter appears to have immense anger and abrupt displays of power that acquire a high level of violence. With these two attributes overlapping‚ Ovid portrays

BETA PICTORIS: PLANETS? LIFE? OR WHAT? JARA ASTRONOMY 102 SEC 013 The ultimate question is; Is there a possibility that life might exist on a planet in the Beta Pictoris system? First‚ one must ask‚ Are there planets in the Beta Pictoris system?. However‚ that question would be impossible to answer if one did not answer the most basic questions first; Where do planets come from? and do the key elements and situations‚ needed to form planets‚ exist in the Beta Pictoris system?.
