Venus (mythology) - Venus (mythology) The Birth of Venus, by Botticelli Venus is the Roman goddess of love, equivalent to Greek Aphrodite and Etruscan Turan. Other figures possibly corresponding to Venus are: Tlahuizcalpantecuhtli in Aztec mythology Kukulcan in Maya mythology Sif in the Norse mythos Her cult began in Ardea and Lavinium, Latium. On August 18, 293 BC, her oldest temple was built. August 18 was then a festival called the Vinalia Rustica. On April 1, the Veneralia was celebrated in honor of Venus Verticordia, the protector against vice. On April 23 215 BC, a temple was built on the Capitol dedicated to Venus Erycina to commemorate the Roman defeat at Lake Trasum. Julius Caesar introduced Venus Genetrix as a goddess of motherhood and domesticity. Venus was often depicted.

Interplanetary travel - not, they would have "left" the system or fallen into the star long ago. This implies that one cannot simply point oneself at another planet and fly in that direction, because upon arrival the planet will be moving at an inappropriate relative velocity or may have moved altogether. For instance, if a spacecraft were to start from the Earth and fly to Mars, its final velocity will be close to Earth's orbital velocity which is much higher than that of Mars. This is because any spacecraft starting on a planet is also in orbit around the sun, and a brief glance at the planetary speeds and distances demonstrates that the power of a rocket pales in comparison to the relative speeds of the planets. In order to make interplanetary travel possible,.
Inferior and superior planets - Inferior and superior planets The terms "inferior planet" and "superior planet" were coined by Copernicus to distinguish a planet's orbit's size; in relation to Earth. "Inferior planet" is generally used in reference to Mercury and Venus; although it can be used to refer to any planet with a smaller orbit than some planet, X. Copernicus determined that these planets were, relatively, close to Sol, as they always appeared in its proximity. (See also: elongation) "Superior planet" is generally used in reference to Mars, Jupiter, and Saturn, Uranus, Neptune, and Pluto; although, it can be used to refer to any planet with a larger orbit than some planet, X. Copernicus determined that Mars, Jupiter and Saturn were, relatively, far from Sol after noting that they were often on the opposite side of.
Vulcan (planet) - Vulcan (planet) Vulcan is a hypothetical small planet that orbited between Mercury and the Sun. Reasons for Vulcan's existence Vulcan was proposed to explain a small perturbation in Mercury's orbit from the path predicted by classical mechanics, technically called advancing perihelion. During Mercury's orbit, its perihelion advances by a small amount each orbit. The measured value is about 43 arcseconds in a century. Even if very small, this result is incompatible with the laws of Kepler and Newton. This idea and the name "Vulcan" was postulated by the French mathematician Urbain Le Verrier in 1859, closely following his spectacular success in "discovering" the planet Neptune in the same way - using only calculus. Various persons and astronomers around the world attempted to prove the existence of said.
Hypothetical planet - Hypothetical planet Hypothetical planets are planets and other heavenly bodies that have been suggested as possibly existing (or have been believed to exist), but have never been proven to actually exist. This includes bodies that have later been proven not to exist. Examples of such hypothetical planets in astronomy or in ancient mythologies include: Planets which would have a direct influence on Earth: Counter-Earth: An Earth-like planet on Earth's orbit but on the other side of the Sun (hypothesized by the Pythagoreans; used by John Norman as the setting for his Gor novels) Theia, a hypothetical planet which was destroyed in a collision with Earth according to the giant impact theory Nibiru/Marduk and Tiamet, two planets from Sumerian mythology which supposedly collided to form Earth (a theory.

Terrestrial planet - Terrestrial planet A terrestrial planet is a planet which is mostly composed of silicate rockss. The term is derived from the Greek word for Earth, "Terra", so an alternate definition would be that these are planets which are, in some notable fashion, "Earth-like". Terrestrial planets are substantially different from gas giants, which may not have solid surfaces and are composed mostly of some combination of hydrogen, helium, and water -- existing in various physical statess. Terrestrial planets all have roughly the same structure: a central metallic core, mostly iron, with a surrounding silicate mantle. Luna is similar, but lacks an iron core. Terrestrial planets have canyons, craters, mountains, and volcanoes. Earth's solar system has four terrestrial planets: Mercury, Venus, Earth and Mars. At one time there were.
The Planets - on October 10, 1920 in Birmingham, with Appleby Matthews conducting. The suite has seven movements, each of them named after a planet (and its corresponding Roman deity): Mars, the Bringer of War Venus, the Bringer of Peace Mercury, the Winged Messenger Jupiter, the Bringer of Jollity Saturn, the Bringer of Old Age Uranus, the Magician Neptune, the Mystic The concept of the work is astrological rather than astronomical (that’s why Earth is not included), and was suggested to Holst by Clifford Bax who introduced him to astrology. Each movement is intended to convey ideas and emotions associated with the Roman deity in question. The Planets is scored for a large orchestra, including an organ and, in the last movement, a wordless women’s choir. Holst’s use of orchestra in this work is.

Planet - Planet simple:Planet A planet (from the Greek "planetes" or "wanderers") is a body of considerable mass that orbits a star and that doesn't produce energy through nuclear fusion. Prior to the 1990s only nine were known (all of them in our own Solar system). As of the end of 2002 over 100 are known, with all of the new discoveries being extrasolar planets. Astronomers often call asteroids minor planets, and call the larger planetary bodies (those which are commonly called planets) major planets. Planets within the solar system can be divided into categories according to composition. Those that are similar to Earth - with bodies largely composed of rock - are called terrestrial or rocky planets. Those with a composition largely made up of gaseous material,.

Planets in science fiction - themes of science fiction. During the first decades of science fiction, Mars was the most common planet and the most romanticized of our solar system whose surface conditions seemed closest to being amenable to life. Percival Lowell's idea about canals of Mars was taken at face value then. Currently Mars is depicted mainly as a target of terraforming. See Mars in fiction for more details on the red planet's numerous roles. During the early-to-mid 20th century, Venus was also a popular subject. Venus is very similar to Earth in its size and surface gravity, and its surface is hidden by a thick cloud layer. Venus was usually depicted as a warm, wet, jungle- and marsh-covered world where life was plentiful, with often thinly-veiled allegories of the European colonization of Africa. Venus.

Venera - series of satellites was developed by the USSR for the gathering of data from Venus. They were relatively successful after the initial glitches were sorted out. As with some of the USSRs other satellite series they were launched in pair with a second satellite being launched soon after (a week or two) the first of the pair. 1VA (proto-Venera) - Flyby - launched February 4, 1961 : Failed to leave earth orbit Venera 1 - Flyby - launched February 12, 1961 : Communications lost enroute to Venus Venera 2 - Flyby - launched November 12, 1965 : Communications lost just before arival Venera 3 - Atmospheric Probe - launched November 16, 1965 : Communications lost just before atmospheric entry Venera 4 - Atmospheric Probe - launched June 12, 1967 : Arrived.
