Volcanism and tectonism are the dominant endogenic means by which planetary surfaces change this book, in general, and this overview, in particular, aim to encompass the broad range in character of volcanism, tectonism, faulting and associated interactions observed on planetary bodies across the inner solar system. The definition of a planet is the subject of vigorous scientific debate. If the milky way galaxy were shrunk down to the size of north america, our solar system would fit inside a coffee cup our solar system is made up of a star that we call the sun , along with eight or nine planets (more on that later): mercury, venus , earth, mars, jupiter, saturn, uranus, neptune and the most controversial:. Sun's period of rotation at the surface varies from approximately 25 days at the equator to 36 days at the poles deep down, below the convective zone, everything appears to rotate with a period of 27 days views of the solar system copyright © 1995-2009 by calvin j hamilton. This lesson will go over the major aspects of our solar system, including the sun, planets, moons, asteroids, comets, meteors, meteorites, and. Solar system overview solar system formation terrestrial planets: moon and mercury earth, venus and mars interiors geology atmospheres life in the solar system giant planets: jupiter and saturn uranus and neptune moons rings pluto / charon cosmic debris - 3 swarms the kuiper belt the oort cloud -. The three major sources for this information are meteorites, the present solar system structure and the planet-forming systems around young stars in this introduction we give an overview of the current understanding of the solar system formation from all these different research fields this includes the question of the lifetime. What is a planet how are planets made what are migrating planets at what point did we realize that the planets, including earth, travel around the sun who was johannes kepler, and what is the significance of his three laws of planetary motion an overview is given of the solar system, the sun and the planets.
Topic 1: solar system overview bill arnett's ss montage the planets of the solar system fall into two general categories: the terrestrial planets (like the earth ) and the jovian planets (like jupiter) the terrestrial planets- mercury, venus, earth and mars- are relatively small and have rocky crusts and small atmospheres. Here's the order of the planets, starting nearest the sun and working outward through the solar system: mercury, venus, earth, mars, jupiter, saturn, uranus, neptune — and planet nine below is a brief overview of the eight primary planets in our solar system, in order from the inner solar system outward. Lecture 3: our solar system – the planets o overview: o what is a planet o planetary properties o solar system planets o chapter 3 of introduction to astronomy and cosmology nasa solar dynamics observatory what is a planet o finally defined in august 2006 by the international astronomical union (iau) o why.
In addition to the above description, some scientists impose additional constraints regarding characteristics such as size (eg, the object should be more than about 1,000 km the eight planets of the solar system and pluto, in a montage of images scaled to show the approximate sizes of the bodies relative to one another. We compare the properties of the planets to learn how the solar system formed and why the earth is such a special place key points: terrestrial and giant planets range of properties with distance from sun and what drives them retention of gas and atmospheres.
This is the solar system this means everything flying round the sun the sun is that flaming ball in the center other balls are planets flying around it on their ellipses the first four planets are near to the sun we call them mercury, venus, earth and mars the small ball near to the earth is earth's moon. The solar system: summary a few of the things that we have learnt about the solar system: planets are celestial bodies that do not emit their own light, they just reflect that of the sun: the stars, instead, are light sources the sun is the only body in the solar system that emits light (that is, it is the only star) the sun stays at the. This section is a sampling of solar system bodies, selected for size and quality of imagery, and sorted by volume some omitted objects are (planet) mars 23 aug 2003 hubble (cropped)jpg ganymede g1 true-edit1jpg two halves of titanpng mercury in color - prockter07-edit1jpg.
The solar system consists of a central star, the sun, and all of the smaller celestial bodies that continuously travel around it the smaller bodies include eight planets: mercury, venus, earth, mars, jupiter, saturn, uranus, and neptune, which are themselves orbited by more than 140 moons (only mercury and venus have no.
Solar system review: our solar system consists of a star of average size and luminosity we call the sun, the planets (in order of their distance from the sun) mercury, venus, earth, mars, jupiter, saturn, uranus, neptune, and kuiper belt objects (eg, dwarf planets like pluto), the satellites or moons of the planets, numerous. This website is an easy-to-follow overview of the historical, scientific, cultural and mythological facts of our solar system topics include space facts, the planets, galaxies, black holes and other objects found in the solar system there are many interactive sections to the site such as the interactive animated orbit and the. A brief introduction to the 8 planets in our solar system. The first stop in this overview of our solar system is the orbits of the planets up until recently, there were nine planets but now, there are only eight that are recognized, thanks to the decision to remove pluto from the list it also contains the sun, which is an average size star and it is located in the centre of our solar system.
