I'm asking all you smart people: Can you please list all the planets and their relative diameter and mass?

Actually there is no tenth planet. Although Pluto is an official planet, others objects of about the same size, or even slightly larger won't be officially recognized as planets.\n\nAn object would need to be much larger, say the size of Neptune to become and official 10th planet. And some astronomers think that should an object may be out there.

Venus, Mars, Mercury, Pluto and that new one are big rocks just like Earth, whereas Jupiter, Saturn, Uranus and Neptune are balls of gas.\n\nMars and Venus are the most comparable in mass (with Venus very close and often called our sister planet).  Mars has polar ice caps.

As of right now we don't know sizes of other planets outside our solar system.\n\n But, Jupiter is the largest planet in the Solar System. With an equatorial diameter of 143,884 km, (89,405 miles), it is as wide as more than 11 Earths stacked side by side. The planet also has the shortest period of rotation - Jupiter days last just under ten hours.

Venus, Uranus and Pluto\n\nI agree with the answer above about Uranus.

All the solar system models you can buy are not to scale, which is OK if all you want to do is show the planets in the right order. But I much prefer a scale model. Only trouble is, it is WAY to big to make indoors. Jupiter is 10 times bigger than Earth and the Sun is 10 times bigger than Jupiter, so if Earth is a 1 inch ball, you need a 10 inch ball to be Jupiter (a basketball is 10 inches) and a 100 inch ball (8 feet 4 inch) for the Sun. Maybe a weather balloon would do. What I did instead was say that the basketball was the Sun, a one inch ball was Jupiter and a 1/10 inch pinhead was Earth. The other planet sizes can be calculated with the first link in the sources below. If the Sun is 10 inches, then Mercury is 34 feet away, Earth is 89 feet away and Pluto is about 2/3 of a mile away. What I did was take the class for a walk outside. We walked 2/3 of a mile from the school, setting up planets as we went. Or you could just set them in a row on the table and have the correct distances written on an information sheet. The whole point is that the planets are really small and really far apart. The models where the sun is only twice as big as Earth just are not convincing.

There are ten planets in our solar system namely mercury,venus,earth mars,jupiter,saturn,uranus,neptune,pluto\nand\n2003-UB313 is the official name of the object that is considered to be a contender for the title of "10th planet". As of August 1st, 2005 the IAU has yet to confirm whether this object will be officially be recognized as the 10th planet in our solar system. This little page will follow events and provide more information when available.\nOfficial Name:  2003 UB313  \nProposed Name:  Unknown\nThe name Xena is rumored to be the name submitted to the IAU for approval, althought there is no official confirmation of the name. "..that was our tongue-in-cheek internal name, never intended for public consumption," says Professor Brown \nDiscovered By: Michael Brown, professor of planetary astronomy at California Institute of Technology (Caltech) and colleagues Chad Trujillo of the Gemini Observatory and David Rabinowitz of Yale University.\n\nFirst photographed in 2003 using a 122cm telescope at the Palomar Observatory. \n \nEstimated Size:  approx 2700 km (1,700 miles) in diameter\nThis is the estimate as of August, 2005. From Wikipedia - Although the object's diameter is not yet well determined, it is estimated to be between 2,390 and 3,550  km . The amount of light it reflects (its albedo ) seems to be quite high, and initial observations show that methane ice is present on the object's surface. Both these properties make it more similar to Pluto than previously discovered large outer solar system planetoids .  \nOrbit: 560 years \nestimated one solar orbit per 560 years.  \nDistance from Sun:\n approx 9 billion miles / 14.4 billion km\nThis is around 100 times the Earth's distance, or 3 times Pluto's distance from the Sun. \nWhere is it Now?  At present, it is near its farthest point from Earth, but in about 280 years, it will be as close as Neptune, (the eighth planet, discovered in 1846).

Go to Heavens Above.  They have a lot of information about the planets, as well as satellites that have been placed in orbit or sent out into the solar system.\n\nhttp://www.heavens-above.com

if we take earth's mass to be "1" then the other planets would be approximately :\n\nmercury = 0.5 ( half )\nvenus     = 1.05\nmars      = .65\njupiter    = 1000 (big)\nsaturn    = 500\nuranus    =400\nneptune  =350\npluto       =0.3

Ten. A new planet has been discovered that is approximately the same size as Pluto. It has not yet been formally named. Check http://www.nasa.gov/vision/universe/solarsystem/newplanet-072905-images.html for more info:)
