Earth
Earth is the third planet from the Sun. It is the densest and fifth-largest of the eight planets in the Solar System. It is also the largest of the Solar System's four terrestrial planets. It is sometimes referred to as the world or the Blue Planet.[23] Earth formed approximately 4.54 billion years ago, and life appeared on its surface within its first billion years.[24] Earth's biosphere then significantly altered the atmospheric and other basic physical conditions, which enabled the proliferation of organisms as well as the formation of the ozone layer, which together with Earth's magnetic field blocked harmful solar radiation, and permitted formerly ocean-confined life to move safely to land.[25] The physical properties of the Earth, as well as its geological history and orbit, have allowed life to persist. Name and etymology In general English usage, the name earth can be capitalized or spelled in lowercase interchangeably, either when used absolutely or prefixed with "the" (i.e. Heat

Venus Venus is a terrestrial planet and is sometimes called Earth's "sister planet" because of their similar size, gravity, and bulk composition (Venus is both the closest planet to Earth and the planet closest in size to Earth). However, it has also been shown to be very different from Earth in other respects. It has the densest atmosphere of the four terrestrial planets, consisting of more than 96% carbon dioxide. The atmospheric pressure at the planet's surface is 92 times that of Earth's. With a mean surface temperature of 735 K (462 °C; 863 °F), Venus is by far the hottest planet in the Solar System. It has no carbon cycle to lock carbon back into rocks and surface features, nor does it seem to have any organic life to absorb it in biomass.

Earth Introduction Earth Introduction My view of our planet was a glimpse of divinity. -Edgar Mitchell, USA From the perspective we get on Earth, our planet appears to be big and sturdy with an endless ocean of air. From space, astronauts often get the impression that the Earth is small with a thin, fragile layer of atmosphere. The Secret Knowledge of The Ancients Number Nine Code 911 The number 9 is the last number in a base 10 system which is the last and limit of all that is. Nine is a number which has many interesting qualities that other numbers do not have and has been used to hold a hidden code that affects every person on earth. If you think nine is just another number, you are in for a big surprise. The number 9 is very interesting and suspect looking like an upside down 6. Even more interesting, there is something about it that most people and scientists don't know.

Structure of the Earth Introduction The Earth is an oblate spheroid. It is composed of a number of different layers as determined by deep drilling and seismic evidence (Figure 1). These layers are: The core, which is approximately 7,000 kilometers in diameter (3,500 kilometers in radius) and is located at the Earth's center. The mantle, which surrounds the core and has a thickness of 2,900 kilometers. Mercury (planet) Mercury is gravitationally locked and rotates in a way that is unique in the Solar System. As seen relative to the fixed stars, it rotates exactly three times for every two revolutions[b] it makes around its orbit.[13] As seen from the Sun, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two Mercurian years. An observer on Mercury would therefore see only one day every two years. Because Mercury's orbit lies within Earth's orbit (as does Venus's), it can appear in Earth's sky in the morning or the evening, but not in the middle of the night. Also, like Venus and the Moon, it displays a complete range of phases as it moves around its orbit relative to Earth.

Earth Earth Earth is a complex, dynamic system we do not yet fully understand. The Earth system, like the human body, comprises diverse components that interact in complex ways. We need to understand the Earth's atmosphere, lithosphere, hydrosphere, cryosphere, and biosphere as a single connected system. Our planet is changing on all spatial and temporal scales. The purpose of NASA's Earth science program is to develop a scientific understanding of Earth's system and its response to natural or human-induced changes, and to improve prediction of climate, weather, and natural hazards. Astrological age There are two broad approaches about the effects upon the world due to the astrological ages. Some astrologers believe the changes upon Earth are caused and marked by the influences of the given astrological sign, associated with the Age, while other astrologers do not follow the causative model and believe it is a matter of synchronicity.[3] Many astrologers believe that the Age of Aquarius has arrived recently or will arrive in the near future.

Mars is currently host to five functioning spacecraft: three in orbit – the Mars Odyssey, Mars Express, and Mars Reconnaissance Orbiter – and two on the surface – Mars Exploration Rover Opportunity and the Mars Science Laboratory Curiosity. Defunct spacecraft on the surface include MER-A Spirit and several other inert landers and rovers such as the Phoenix lander, which completed its mission in 2008. Observations by the Mars Reconnaissance Orbiter have revealed possible flowing water during the warmest months on Mars.[25] In 2013, NASA's Curiosity rover discovered that Mars' soil contains between 1.5% and 3% water by mass (about two pints of water per cubic foot or 33 liters per cubic meter, albeit attached to other compounds and thus not freely accessible).[26] Physical characteristics

Astrological age There are two broad approaches about the effects upon the world due to the astrological ages. Some astrologers believe the changes upon Earth are caused and marked by the influences of the given astrological sign, associated with the Age, while other astrologers do not follow the causative model and believe it is a matter of synchronicity.[3] Many astrologers believe that the Age of Aquarius has arrived recently or will arrive in the near future. On the other hand, some believe that the Age of Aquarius arrived up to five centuries ago, or will not start until six centuries from now.[4] Despite all references provided by various sources, astrologers cannot agree upon exact dates for the beginning or ending of the ages. Various ages are described below, such as the Age of Aquarius. Overview[edit]

core Earth’s core is the very hot center of our planet. The Earth has three major layers. All known life exists on the solid outer layer, called the crust. Beneath the crust is the mantle, a gooey, hot layer of magma and other semi-solid rocks and minerals. Movement in the mantle leads to tectonic activity, such as volcanic eruptions and earthquakes, on the crust. The core, beneath the mantle, is the deepest and hottest layer of the Earth.

Jupiter Structure 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 (88,846 mi) at its equator. The density of Jupiter, 1.326 g/cm3, is the second highest of the gas giants, but lower than for any of the four terrestrial planets.
