[2] The planets The research expands to include the terrestrial planets‚ and their satellites. This involves the physics of the interior‚ the geology of the planet or satellite surface‚ the surface morphology‚ and studying their tectonics‚ mineralogy and dating. Observing the outer planets and their satellites includes studying formation and evolution. This method of observation and study involves remote sensing at all wavelengths and in situ measurements. Planet formation and planet evolution

developed to explain how the planets‚ the sun‚ and even the stars orbit around the earth. Why the geocentric view was a natural one to assume? It was a view of stationary earth and moon‚ planets and sun revolving around it. Ptolemy devised the geocentric theory when it reached its pinnacle with the system. The early Greeks observed the sky and all that it contained. From their observations‚ the Greeks believed the Earth was the center of the moon‚ Sun‚ and the only known planets at that time‚ Mercury

their kingdoms freedom and wealth that they had. Meanwhile in a galaxy not so far away two scientists Pinhead and Pedro of a random distant planet had discovered a technology to jump time and space so they could travel to any planet they wanted and were looking for a happy planet to conquer to celebrate this achievement. These scientists were rewarded with a planet each along with a shampoo named after them and the power to lead this joyous attack of celebration. Little known fact about the people in

from a constant position relative to those two bodies. Robert Forward makes use of this concept quite frequently in Rocheworld to describe the activities of the human space travelers as they explore the binary planet system of Roche and Eau‚ and the unique qualities of these binary planets raise the possibility for Lagrange points that are quite unlike those we observe in our own Solar System. The first Lagrange point‚ called L1‚ is located between the two larger masses. For example‚ in the Sun-Earth

and why is it important? Space exploration is scientific studies using scientific equipment in space and anything about it. There are different reasons why space exploration is important. We could discover new resources from other planets or the moon‚ other planets can be could be used when something happens to the earth and we need another place to stay on. Occupation Space exploration is a well-paid job because it could be very dangerous. You also have to study hard and get good

Jupiter is composed primarily of gaseous and liquid matter. It is the largest of four gas giants as well as the largest planet in the Solar System with a diameter of 142‚984 km at its equator. The density of Jupiter‚ 1.326 g/cm3‚ is the second highest of the gas giant planets. The density is lower than any of the four terrestrial planets. Jupiter’s upper atmosphere is composed of about 88–92% hydrogen and 8–12% helium by percent volume or fraction of gas molecules. Since a helium atom has about

The rings of Saturn and Uranus may seem similar‚ but they are actually very different. The 2 planets ring systems differ mainly in their composition‚ size‚ and number. Saturn has 7 main ring groups that are made up of many other smaller rings. The groups are generally thicker in diameter but can vary. The rings themselves are composed of mainly icy particles. On the other hand‚ Uranus’ rings are broken into 9 sections and are generally thinner in diameter. Uranus’ rings are composed of both icy particles

ONE Saturn is the second largest planet in the Solar System after Jupiter. It is so big that Earth could fit into it 755 times. FACT TWO Saturn is a slightly smaller version of Jupiter‚ with similar‚ but less distinctive‚ surface patterns. Its only main difference is its amazing rings. FACT THREE Saturn’s rings may be particles of an old moon orbiting the planet‚ smashed apart in a collision about 50 million years ago. FACT FOUR Saturn’s rings orbit the planet at different tilts. Sometimes‚ they

states that planets move in elliptical orbits with the sun at one focus. Think of the elliptical shape as a part of a cone. This is the shape of the orbit that becomes an inverse square force‚ which is an intensity in the gravity field. The eccentricity is the ratio of the distance between the foci to the major axis of the ellispe‚ which is basically the orbit of each planet. Since the formula is Ra= a(1+e) and Rp= a(1-e)‚ when e=0 for the orbit‚ we can then calculate the orbit for each planet. These

was discovered in September 1845. It was discovered by means of mathematics before being seen through a telescope. It began in 1843 when John Adams‚ a young English astronomer and mathematician‚ began working to find thew location of the unknown planet. Adams predicted the planned would be about 1.6 billion kilometres farther from the sun then Uranus. That’s when he completed his work in September 1845. Also Urbain Leverriar‚ unknown to Adams‚ began working on the same project. By mid-1846‚ Leverriar
