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.
There could be hundreds more of these small worlds far out there waiting to be discovered. Moons: This count includes only the moons orbiting the eight planets in our solar system. Asteroids: New asteroids are discovered on an almost daily basis. Comets: Orbiting spacecraft such as SOHO have raised this tally in recent years by catching the comets as they plunge toward the Sun - and sometimes vaporize. Mars as big as the Moon: No. Just, no. 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. On this night, the planet Mars will pass just 34.65 million miles from the earth. To the naked eye it looks like two of the moon above the ground! Share the news with your friends, because no one living on this earth has ever seen! Source unknown, but it's all over Facebook.
Every year in August, somewhere, somehow, this silly claim springs from the cold, dead ground, rising once again to shamble across the Internet. This all started in 2003, when an email got spread around claiming that Mars would look as big as the Moon in the night sky on a specific date in August. As far as it went, that was about accurate. Once the date passed, I breathed a sigh of relief. Oh, such naïveté ! Still, this claim is even worse this year than previously. Eight planets. 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. " Eris, originally called 2003 UB313, sometimes called Xena, sometimes called the "10th planet," which in many ways precipitated this final debate, becomes the largest known dwarf planet.
Unless astronomers revisit this issue at some point in the future, it is unlikely that there will ever be more than eight planets. What is a dwarf planet? When the final vote on the definition of "planet" was made, and the eight dominant bodies in the solar system were declared (quite rationally) a class separate from the others, a new class of objects was defined. How many dwarf planets are there? There are two ways to look at this question. Reality, however, does not pay much attention to official lists kept by the IAU or by anyone else. Dwarf 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.

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.
In 1997, Pluto was closer to the Sun than Neptune. Click on image for full size JPL/NASA Pluto has the most eccentric orbit of all the planets in the solar system. That means that Pluto's orbit draws within the orbit of Neptune, as can be seen in this drawing, making Pluto the 8th planet rather than the 9th planet for roughly 20 years at a time. It takes 248 years for Pluto to complete its orbit. In addition to its peculiar orbit, Pluto and its moon Charon are locked together as they orbit each other, so that the same side of each body always faces the other.

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 planetary pairing has its own unique dance rhythm. For example, the Earth-Venus dance returns to the original starting position after eight Earth years. Earth: 8 years * 365.256 days/year = 2,922.05 days Venus: 13 years * 224.701 days/year = 2,921.11 days (ie. 99.9%) Watching the Earth-Venus dance for eight years creates this beautiful five-petal flower with the Sun at the center. (5 is another Fibonacci number.)

Marvin the Martian's front lawn - Franny Wentzel - Saturday, April 24th, 2010 : goo [previous] :: [next] This is the first image ever taken of Earth from the surface of a planet beyond the Moon. It was taken by the Mars Exploration Rover Spirit one hour before sunrise on the 63rd Martian day, or sol, of its mission.
(March 8, 2004) The image is a mosaic of images taken by the rover's navigation camera showing a broad view of the sky, and an image taken by the rover's panoramic camera of Earth. The contrast in the panoramic camera image was increased two times to make Earth easier to see.The inset shows a combination of four panoramic camera images zoomed in on Earth.
