Dwarf Planets: List of Dwarf Planets Planets: The planet count in our solar system has gone as high as 15 before new discoveries prompted a fine tuning of the definition of a planet. The most recent change was in 2006 when scientists reclassified Pluto as a new kind of object - a dwarf planet. Dwarf Planets: This new class of worlds helps us categorize objects that orbit the Sun but aren't quite the same as the rocky planets and gas giants in our solar system.
Oh, is it August already? That means it’s time for the nonsense that is the “Mars will be as big as the Moon” claims once again. Yup. I saw this is getting spread around on Facebook: August 27 at 00:30 Lift up your eyes and look up at the night sky. Mars as big as the Moon: No. Just, no.
Mike Brown On August 24th 2006 the word "planet" was given its first-ever scientific definition by a vote of the International Astronomical Union. With the raising of a few yellow cards in Prague, Pluto was demoted from full-fledged planet to "dwarf planet." Eight planets

The Big Chandra Picture In more than a decade of operation, NASA's Chandra X-ray Observatory has transformed our view of the high-energy Universe with its ability to make exquisite X-ray images of star clusters, supernova remnants, galactic eruptions, and collisions between clusters of galaxies. As Chandra expands the realm of the known, it continues to raise new questions and point the way for future exploration. This photo blog presents some of Chandra's most spectacular images in a large and shareable format. Chandra :: Photo Album :: The Big Chandra Picture

Pluto's Orbit This is a drawing showing the orbit of Pluto and the outer planets. It shows the planets on June 1, 1997. In the larger version at least, you can see dots next to the names indicating planet position.
Ensign Software - ESPL: Dances of the Planets The planets in the heavens move in exquisite orbital patterns, dancing to the Music of the Cosmos. There is more mathematical and geometric harmony than we realize. The idea for this article is from a book Larry Pesavento shared with me. The book, 'A Little Book of Coincidence' by John Martineau, illustrates the orbital patterns and several of their geometrical relationships. . Take the orbits of any two planets and draw a line between the two planet positions every few days. Because the inner planet orbits faster than the outer planet, interesting patterns evolve.

Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2011 May 7 Dawn of the Planets Image Credit & Copyright: Luis Argerich Explanation: This month, four of the five naked-eyeplanets gather along the eastern horizon near dawn. The celestial grouping is seen here just before sunrise on May 5, from a beach near Buenos Aires, Argentina.
