PLANETOLOGY Planetology is the branch of astronomy that deals with the physical features of the planets. Planetology studies include the origin and composition of the planets‚ and the solid bodies of comets and meteors found in the solar system. Comet‚ Asteroid‚ and Meteor An asteroid and a comet are very similar‚ and yet at times they are unique and easily distinguishable from each other. An asteroid and a comet are both a small solar body system‚ rotating around the sun. An asteroid consists

Johann Gottfried Galle Johann Gottfried Galle was born on June 9‚ 1812‚ in Papsthaus‚ Germany. He was a German astronomer and the very first to sight the planet Neptune and was conscious of at what he saw in the night sky. The detection of Neptune is one of the most extraordinary events of the century. Growing up‚ Galle attended a Gymnasium located in Wittenberg and from 1830-1833 he continued his studies at Friedrich-Wilhelms-Universitat‚ Berlin. Galle then became a teacher and taught physics

is in the Sun. Of the many objects that orbit the Sun‚ most of the mass is contained within eight relatively solitary planets whose orbits are almost circular and lie 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‚ the gas giants‚ are substantially more massive than the terrestrials. The two

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

Sec 2 Uranus is the 7th planet from the sun The average distance from Uranus to the sun is 2‚877‚000‚000 km. It takes 84.02 Earth years for Uranus to Orbit around the sun. Each Uranus day is equal to 17.24 Earth hours. Uranus is a greenish blue planet‚ it rotational axis different from all other planets as it rotates on its side‚ like a ball. Sec 3 Uranus is 50‚724 km in diameter and it is the third largest planet. There are 27 known moons orbiting Uranus

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

What questions were asked? There weren’t as many questions asked as a normal scientific discovery since it is claimed that Herschel discovered the planet Uranus by accident. However‚ as his discovery began to progress‚ many questions came about like ones about the satellites near Uranus. Herschel had discovered that there
