Six of the planets are orbited by one or more natural satellites. Jupiter is the largest, at 318 Earth masses, while Mercury is smallest, at 0.055 Earth masses. The names for the planets in the Western world are derived from the naming practices of the Romans, which ultimately derive from those of the Greeks and the Babylonians. Today, most people in the western world know the planets by names derived from the Olympian pantheon of gods. When the Romans studied Greek astronomy, they gave the planets their own gods' names: Mercury (for Hermes, God of Commerce and Thievery), Venus (Aphrodite, Goddess of Wisdom), Mars (Ares, God of War), Jupiter (Zeus, King of Gods), Saturn (Cronus, father of Zeus), Neptune (Poseidom , God of Ocean), Pluto (Hades, God of Underworld) and Uranus (Rhea, Goddess of life).
The crust of the Moon is composed of a variation of primary elements, including uranium, oxygen, thorium, potassium, silicon, magnesium, iron, titanium, calcium, aluminum and hydrogen. The Moon exhibits many same materials and characteristics as early Earth. Moon rocks and cores that the Apollo missions yielded back to Earth proved the Moon to be covered with ancient basaltic lava flows. The Moon’s surface is covered by a dusty outer rock layer called regolith. The Moon shows considerable evidence of past volcanic activity.
In 1780, a man by the name of Herschel discovered our seventh planet; Uranus. Finally, in the early 1930's the 9th and final planet at the time Pluto was discovered. We will look in depth at each advancement in these period and how they lead to the advancement of technology and philosophies. In 1543, while on his deathbed, Polish astronomer Nicholas Copernicus published his theory that the Sun is a motionless body at the center of the solar system, with the planets revolving around it. Before the Copernicus system was introduced, astronomers believed the Earth was at the center of the
The 10.8% increase in the President’s FY 2011 budget for planetary science signifies the . The Pioneers of Space Exploration In 2006, NASA collaborated with the National Research Council to develop a Solar System Exploration Roadmap for its Science Mission Directorate to be executed over the next 30 years. The basis behind the roadmap is to answer fundamental questions such as, how did life begin and evolve on Earth and has it evolved elsewhere in the Solar System? Since the Ranger mission in 1961, there have been 43 planetary explorations in development or completed. [Need a Title] The Sun’s Origin and the Evolution of the Solar System Scientists must understand the evolution of terrestrial planets and to discover the possible varieties and causes of diverse planetary environments.
Phobos will eventually crash into Mars or break up and form a ring around the planet. Deimos (which means fear) was named after the Greek God Deimos who was the twin brother of Phobos. Deimos is the outer moon so it is further away from Mars and takes about 30 hours to orbit. It is small and lumpy and has lots of craters and is covered in dust and loose rocks. Although it has many craters it’s surface is much smoother than Phobos’ Deimos has an average radius of 6.2
The main areas when discussing a space settlement are Design, Technical Engineering, Construction, Life Design, Automation and Defense and Research, Business and Expansion. The first issue that comes to one’s mind when designing a space settlement is its orbital location. Although orbits like LEO, GEO or locations as one of the Earth’s Lagrangian points sound feasible, in my opinion, placing a space settlement around the Sun is ideal. The Sun is the source of life throughout our Solar System, and in the case of an orbital settlement, it would offer 24/7 electrical power as well as the very-needed natural sunlight. Since it will orbit the Sun, this
Waterworld planet is more Earth-like than any discovered before Astronomers spotted the waterworld orbiting a star in our cosmic backyard, raising the chances that we will eventually discover planets suitable for life Share483 • • • inShare0 [pic] • [pic]Email [pic][pic] Planet GJ 1214b orbiting its red dwarf star. The Hubble telescope will reveal whether it is suitable for life. Artist's impression: David A. Aguilar/CfA A giant waterworld that is wet to its core has been spotted in orbit around a dim but not too distant star, improving the odds that habitable planets may exist in our cosmic neighbourhood. The planet is nearly three times as large as Earth and made almost entirely of water, forming a global ocean more than 15,000km deep. Astronomers detected the alien world as it passed in front of its sun, a red dwarf star 40 light years away in a constellation called Ophiuchus, after the Greek for "snake holder".
The Effects the Moon has on Earth As the moon dances along its orbit in uniform motion with the earth, we see it going from a new moon to full moon and back. We normally think that the moon has no effect on us whatsoever, but in reality, we wouldn’t be where we are now without the moon. The effects the moon has on the earth are ocean tides, the length of our day, months, and animal behavior. The moon tries to pull the earth closer with its gravity. But with the earth being three times more massive than the moon, it is able to stay in place.
While moving through space these objects are known as meteoroids. The bright streaks that they produce while moving through Earth’s atmosphere are known as meteors. The term meteorite is also used for a meteoroid that has landed on the surface of a celestial body other than Earth. There are three main types of meteorites. The most abundant are stone meteorites which are primarily made up of silicate minerals such as olivine, pyroxene, and feldspar.
The fact that Earth hosts not just life, but intelligent life, makes it doubly unique. And the planet's intelligent life (humanity) has even developed rockets that enable travel beyond the planet, said Gregory Laughlin, astrophysicist and planet hunter at the University of California, Santa Cruz. "During the last half century, the planet Earth has fashioned together tiny pieces of the metal in its crust, and has flung these delicately constructed objects to all of the other planets in the solar system," Laughlin said, adding that these achievements should be counted as an exemplary trait of our planet. "From our anthropocentric viewpoint, we naturally separate ourselves from the planet that we live on, but if one adopts the point of view of an external observer, it is the 'planet' (taken
