WHAT IS GEOGRAPHY? EARTH RECAP Lorge number of h put forth by different phi ond scientists regording the Origin of the earth Big Bang Theory pwere Origin of the Univ Origin of the earth Origin of the Universe M\ MODERN THEORIES EARLY THEORIES
SOLAR SYSTEM FORMATION OF PLANETS Jovian Close vicinity of the parent star * long location from Parent star Where is Pluto . Intense solar . Not that intense winds planets are planets hold huge amount of gases " International Astronomical Union DWARF PLANT A celestil body orbiting a star that is mosslve enough to be rounded by its own gravity but has not cleared its neighboring reglon of planetesimals ond is not a satellite. More explicitly, it has to hove sufficient mass to overcome its compressive strength and achieve hydrostatic equilibrium. Inner Planets 1. Must be in direct orbit of the Sun and not be a moon around another body. 2. It must be mossive enough for it to have become spherical in shape Outer Planets under its own gravity Jovian or Gas
JUNO MISSION UNIVERSE Powered by Solar arrays Cope Canoveral Air Force Station All existing matter and space as a whole forms Universe Study Jupiter's composition, gravity field, magnetic field, and polar magnetosphere. COSMOS Believed to be expanding since its creation in the Big Bang Normal matters all that are visible (star, planet ahd galaxies) make up less than 5 %of the total mass of the universe rest are made of dark matters. Theso dark matters are not seen by the astronomers but cart stody their-effects. : Galaxies GALAXY System of millions or billions of stars held together by the gravitational attraction between gas and dust large collection of stars, gos, dust, and dark matter bounded by gravitational force Spiral Galaxy Elliptical Galaxy Irregular Galaxy Island Universe The studies related to the distant spaces with optical and radio telescopes indicate that about 100 galaxies are visible universe
STAR FORMATION Galaxies spread over vast distances that are measured in thousands of light- years. The diameters of individual galaxies range from 80,000-150,000 light years. A galaxy starfs to.form by, accumulatian of hydrogen gas in the form of a very large cloud called nebula. Eventually, gr wing nebula develaps localised clumps of gas. These lumps continue to grow into even denser gaseous bodies, giving ri e to formation of stars The formation of stars is believed to have taken place some 5-6 billion years ago
WHAT IS A LIGHT YEAR? We see t not pas the present A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km)
Sun Light travels at a speed of 186,000 miles (or 300,000 km) per second Moon 8.3 minutes Earth
How many light-years away? Earth is approximately... 4.3 light-years away from Proxima Centauri, our closest neighboring star 8.3 light-minutes from the Sun *320 light-years 26,000 light-years away from the center of our galaxy, the Milky Way from the North Star, Polaris 2.5 million light-years 13.4 billion light-years away from one of the oldest galaxies ever found, called GN-z11 R from Andromeda, our closest neighboring galaxy
MOON Formation of moon, as a satellite of the earth, is an outcome of giant impact or what is described as "the big splat". A body of the size of one to three times that of mars collided into the earth sometime shortly after the earth was formed. It blasted a large part of the earth into space. This portion of blasted material then continued to orbit the earth and eventually formed into the present moon about 4.44 billion years ago.
