Introduction to Astronomy Week 3 The Solar System When you have completed this topic, you will have a better understanding of : the solar system, the sun and its many planets; the process of observing the planets and their satellites; the process of discovering extra-solar planets; general links to relevant web pages Some of the topics in this session are devoted to our sun and its planets that make up the solar system. I have prepared another U3A course on this topic to which you can refer through the Astronomy Awareness page here. These contain a scale model of our system, based on the city of Canberra. The sun The sun is our nearest star, but until recently we understood more about distant suns than our own. Several web sites provide up-to-date information on our nearest star and we will use these to complete this section of Week 3. Activity: Check these links This link provides data and images concerning our sun http://www.seds.org/billa/nineplanets/sol.html The following link provides details of the NASA/European Space Agency's Solar and Heliospheric Observatory (SOHO) satellite, which is orbiting the sun inside the earth's orbit to collect data from the sun with a wide range of instruments. Our knowledge of the sun has been increased dramatically from the data obtained. Press releases and images of the sun are available from this site. http://sohowww.nascom.nasa.gov/

26. Terrestrial Planet Finder Explains NASA s plan to use sensitive telescopes to find planets outside of the solar-system. Includes charts and drawings. http://www.terrestrial-planet-finder.com/

document.write(''); Links to other spacel sites Visit our linking partners below (please report any abuse to This site is using " ". a Space telescope to find planets outside from our solar-system as small as Earth Short Introduction The Terrestrial Planet Finder (TPF) uses a small collection of high sensitivity telescopes (probably 4 large 3.5-meter telescopes) with revolutionary imaging technologies. It will measure the temperature, size, and the orbital parameters of planets as small as our Earth in the habitable zones of distant solar systems. Also, TPF's spectroscopy will allow atmospheric chemists and biologists to use the relative amounts of gases like carbon dioxide, water vapor, methane and ozone to find whether a planet might support life. Launch is anticipated between 2012-2015. "The discovery of life on another planet is potentially one of the most important scientific advances of this century, let alone this decade, and it would have enormous philosophical implications." - National Research Council One great challenge is how to detect planets against the blinding glare of their parent star. TPF with 4 big telescopes, will reduce the glare of parent stars to see planetary systems up to 50 light-years away.

29. When Is A Planet Not A Planet? - 98.02 Articles discusses the debate whether Pluto should be included among the planets. Atlantic Monthly http://www.theatlantic.com/issues/98feb/pluto.htm

Return to the Table of Contents. F E B R U A R Y 1 9 9 8 Arguments for and against demoting Pluto by David H. Freedman Discuss this article in the forum of From the archives: (June, 1997) A look back at some Atlantic articles on space research. by Freeman J. Dyson (November, 1997) A consideration of the possible future of space exploration. T HE planet Pluto has been shrinking at an alarming rate for some time now. Well, not actually shrinking rather, our awareness of how small Pluto is has been growing. Upon its discovery, in 1930, scientists trumpeted that Pluto was about as large as Earth. By the 1960s textbooks were listing it as having a diameter about half that of Earth. In 1978 astronomers discovered that Pluto has a relatively large moon, whose brightness had been mistakenly lumped in with the planet's; when this was taken into account, Pluto was left with a diameter about a sixth that of Earth, or less than half that of Mercury long considered the runt of the solar system. Seven moons in the solar system are bigger than Pluto. In addition to being out of place among the planets in terms of size, Pluto has always seemed conceptually lost as well. The four innermost planets are rocky and of modest size; the next four are gas giants. What was a lone, tiny ice ball doing way out at the edge of the solar system? A surprising answer has emerged over the past few years. Pluto, it turns out, is one of at least sixty, and possibly hundreds of thousands of, small, cometlike objects in a belt that extends far beyond the confines of the planets.

This picture below shows how big (and little!) the nine planets are in relation to each other. Can you see tiny Mercury in the very bottom, left-hand corner? Pluto is the teeny-tiny planet in the very top, right-hand corner! These nine planets are grouped in many different ways. Two easy groupings are composition (what they are made up of) and size COMPOSITION ROCKY PLANETS Mercury Venus Earth Mars ... Pluto The rocky planets are mostly made up of rock and metal. These planets are very heavy and move slowly. They also do not have rings and very few moons. GAS PLANETS Jupiter Saturn Uranus Neptune The gas planets are mostly made up of gases (hydrogen and helium). These planets are light for their sizes (just like a big air balloon) and move quickly. They have rings and lots of moons. SIZE SMALL PLANETS Mercury Venus Earth Mars ... Pluto The small planets have diameters less than 13000 km across. Mercury and Pluto are sometimes referred to as

34. PLANETS Formation Process Article from a book by Angel Fernando Vitoria. http://www.planetsformation.netii.net/

PLANETS FORMATION PLANETARY FORMATION PROCESS ESPAÑOL Our starting point to planetary formation and solar systems formation process are the stellar systems. STELLAR SYSTEMS FORMATION Solar systems and stellar systems both have very similar structures. Typically, stellar systems have one or more central masses (normally one) and a number of minor masses, mainly dwarf stars, orbiting around the center in a discal or plane fashion. Similarly, solar systems also have a central main star (the sun) and a number of minor masses (the planets) orbiting around the central sun, also in a discal or plane fashion. TRANSFORMATION PROCESS FROM YELLOW DWARF TO PLANET. When it comes to planetary formation, it is important to consider the size, the mass and the structural characteristics of planets themselves as compared with the size, mass and structural characteristics of dwarf stars orbiting in stellar systems as their conformation is very similar. A very important point is that both, dwarf stars and planets, do have a nucleus and a spherical structure. In the planets formation process, the nucleus of the original minor stars orbiting (yellow dwarfs) becomes the nucleus of the new planets, enveloped and protected by the cortex. Hubble S. T. Photo.

36. Venus  L  Venus Facts, Pictures And Information. From The Nine Planets. http://www.nineplanets.org/venus.html

Venus The Bringer of Peace Venus is the second planet from the Sun and the sixth largest. Venus' orbit is the most nearly circular of that of any planet, with an eccentricity of less than 1%. orbit : 108,200,000 km (0.72 AU ) from Sun diameter : 12,103.6 km mass : 4.869e24 kg Venus (Greek: Aphrodite ; Babylonian: Ishtar) is the goddess of love and beauty. The planet is so named probably because it is the brightest of the planets known to the ancients. (With a few exceptions, the surface features on Venus are named for female figures.) Venus has been known since prehistoric times. It is the brightest object in the sky except for the Sun and the Moon. Like Mercury , it was popularly thought to be two separate bodies: Eosphorus as the morning star and Hesperus as the evening star , but the Greek astronomers knew better. (Venus's apparition as the morning star is also sometimes called Lucifer.) Since Venus is an inferior planet, it shows
