The Nine Planets: Earth
General information, some statistical data and links.
Earth Terra, Sol III Earth is the third planet from the Sun and the fifth largest: : 149, 600, 000 km (1.00 ) from Sun : 12, 756.3 km : 5.972e24 kg Amazing pictures of Earth from space combine useful science and artistic beauty
Kids often ask me which is my favorite planet
Earth is the only planet whose English name does not derive from Greek/Roman mythology
There are, of course, hundreds of other names for the planet in
It was not until the time of (the sixteenth century) that it was understood that the Earth is just another planet
Nevertheless it was not until the twentieth century that we had maps of the entire planet
Pictures of the planet taken from space are of considerable importance; for example, they are an enormous help in weather prediction and especially in tracking and predicting hurricanes
Note, however, that our knowledge of planetary interiors is mostly theoretical even for the Earth
Unlike the other planets, which float around independently on top of the hot mantle below
Earth is the only planet on which water can exist in liquid form on the surface (though there may be liquid ethane or methane on surface and liquid water beneath the surface of )

This force of attraction between you and the Earth (or any other planet) is called your weight
First, it depends on your mass and the mass of the planet you are standing on
If the planet you are standing on is twice as massive, gravity also pulls on you twice as hard
On the other hand, the farther you are from the center of the planet, the weaker the pull between the planet and your body
Pluto
Complete guide regarding general and statistical data about this planet and Charon.
Includes pictures and links to other related sites. By Rosanna Hamilton.
Table of Contents Pluto Introduction Pluto's Moons Pluto Science Other Resources Although Pluto was discovered in 1930, limited information on the distant planet delayed a realistic understanding of its characteristics
Today Pluto remains the only planet that has not been visited by a spacecraft, yet an increasing amount of information is unfolding about this peculiar planet
The uniqueness of Pluto's orbit, rotational relationship with its satellite, spin axis, and light variations all give the planet a certain appeal
Pluto is usually farther from the than any of the nine planets; however, due to the eccentricity of its orbit, it is closer than for 20 years out of its 249 year orbit
Although it is common for a satellite to travel in a with its planet, Pluto is the only planet to rotate synchronously with the orbit of its satellite
Unlike most planets, but similar to, Pluto rotates with its poles almost in its orbital plane
There is a thin atmosphere that freezes and falls to the surface as the planet moves away from the Sun
NASA plans to launch a spacecraft, the Pluto Express, in 2001 that will allow scientists to study the planet before its atmosphere freezes

Uranus
Views of the Solar System, Calvin J. Hamilton.
- Albert Einstein Table of Contents Uranus Introduction Satellites of Uranus Uranus Science Other Resources Uranus is the seventh planet from the Sun and is the third largest in the solar system
Winds at mid-latitudes on Uranus blow in the direction of the planet's rotation
Its unusual position is thought to be the result of a collision with a planet-sized body early in the solar system's history
found that one of the most striking influences of this sideways position is its effect on the tail of the magnetic field, which is itself tilted 60 degrees from the planet's axis of rotation
The was shown to be twisted by the planet's rotation into a long corkscrew shape behind the planet
The magnetic fields of Earth and other planets are believed to arise from electrical currents produced in their molten cores
Hamilton) The Interior of Uranus Our knowledge of the internal structure of Uranus is inferred from the planet's radius, mass, period of rotation, the shape of its gravitational field and the behavior of hydrogen, helium, and water at high pressure
These elements are under high temperatures and pressures deep within the planet

Modern science, using information from both past and current spacecraft, paints a more fascinating picture of the Red Planet than even the movie industry has been able to dream up
Mars is the only planet where the average backyard astronomer can actually see the seasons change
Amateurs using a moderately sized telescope in good viewing conditions, can actually see the polar ice caps on Mars get bigger and smaller as the planet goes through summer and winter
A Frigid Desert When early astronomers started looking at Mars through their primitive telescopes, they could see that the planet seemed to change colors as time passed, with dark areas on the surface of the planet growing and then shrinking as time passed
Also, there appeared to be dark lines on the surface of the planet that some overenthusiastic observers thought were canals made by intelligent life forms on the planet

As a matter of fact, there are two moons in the solar system that are larger than this planet! Jupiter's moon Ganymede and Saturn's moon Titan are both larger than the closest planet to the Sun
In addition, the surface temperature on Mercury varies widely, with the side of the planet facing the Sun having an average temperature of over 650 degrees Fahrenheit, while the 'dark' side of the planet has an average temperature less than 270 degrees below zero Fahrenheit
Even though Mercury is one of our closest planetary neighbors, we don't know a whole lot about it
Since the planet is so close to the Sun, it's not safe to have the Hubble Space Telescope take pictures of it

Earth has one moon, but some planets have over 30
They are the remnants from early planets that collided and were torn apart
Over time, the gas cooled and clumped together to form large bodies called 'protoplanets'
People of the ancient world observed the movements of the planets and thought they were wandering stars
This is why the Greeks gave them the name planetes or 'wanderers'

The Dwarf Planet: Pluto is smaller than 7 of the moons in the Solar System
Because it is so small many scientists don't consider it a planet at all
On August 24th, 2006 Pluto's status was officially changed from planet to dwarf planet
For decades children have been taught that there are nine planets in the Solar System
However, with this change, there are now only eight planets
Because we have never sent probes to this planet we know very little about it
The Earth and it's moon Luna are sometimes considered double planets

ORRERY: Saturn - ringed beauty
General information about the planet and its moons presented in a popular language.
Saturn - ringed beauty | Saturn | Saturn is the sixth planet from the Sun
There are 22 moons orbiting the planet, 4 of which were discovered in summer 2000
is the largest (diameter 5, 150km), and is the only planetary satellite known to have an atmosphere, mainly nitrogen
Day & Night Just like all the other planets, Saturn is visible because it reflects the 's light
The left side of the planet is in shade: night
Ringed Beauty The planet has an extensive system of rings, composed of icy particles ranging in size from pebbles to beach balls

Under Study After a brief fly-pass by Pioneer 11 in 1979, Voyagers 1 and 2 sent back much important information about the planet, its satellites and rings during their encounters in 1980 and 1981
A Typical Giant The composition of the planet is very similar to that of, with a silicate core surrounded by liquid hydrogen, and a deep gaseous hydrogen atmosphere

Is Pluto a giant comet?
Discusses related discoveries and excerpts.
Well, then, is Pluto a planet? Yes, it appears to be a planet
But it is reasonable to qualify that by saying that Pluto is not a major planet because it is simply too small to be a major planet (though the pride of many American astronomers causes them to continue to fight politically for Pluto to be called 'one of the nine major planets')
It is a planet of some sort, and many planetary scientists in the last couple of decades of the 20th century began speaking of Pluto as a 'planetesimal' -- and no longer as a 'major planet' -- in the astronomical literature (note the several dozen authors in the documented list below)
There is no need to have an 'edict' saying that Pluto is not the ninth major planet, as astronomy doesn't really work that way, and the field is gradually but steadily moving toward an eventual universal acceptance of a new picture of the solar system that places Pluto in a different (but still significant) light
And, yes, it might be that we will want to consider placing Pluto in different categories, such as (minor) planet and comet
Such 'dual status' already exists for some comets and minor planets, which are given formal numbers and names in both kinds of catalogues

Ne (continued...) | Posted by on Thursday, August 24, 2006 (11:46 AM) From Wired.com: Leading astronomers declared Thursday that Pluto is no longer a planet under historic new guidelines that downsize the solar system from nine planets to eight.After a tumultuous week of clashing over the essence of the cosmos, the International Astronomical Union stripped Pluto of the planetary status it has held since its discovery in 1930
The new definition of what is and isn't a planet fills a centuries-old black hole for scientists who have labored since Copernicus without one.Although astronomers applauded after the vote, Jocelyn Bell Burnell a specialist in neutron stars from Northern Ireland who oversaw the proceedings urged those who might be "quite disappointed" to look on the bright side."It could be argued that we are creating an umbrella called 'planet' under which the dwarf planets exist, (continued...) | Posted by on Saturday, August 12, 2006 (12:42 AM) From DPReview: Nikon has today (August 9) put the end to the speculation and announced the new ten megapixel D80 digital SLR

Alan Stern Boulder - Mar 22, 2004 I am a planetary scientist, so you won't find it surprising that this past Monday evening, March 15th, the dinner table conversation at our home eventually turned to the discovery of the largest ever Kuiper Belt Object, Sedna (2003 VB12)
When I remarked that I was amused by the fact that some astronomers don't consider Sedna a planet, our teenage daughter Kate joined in-agreeing that Sedna shouldn't be classified a planet
'Dad, if Sedna is a planet, then Ceres is too, and there are probably lots and lots more things this big that we haven't discovered
We can't have so many planets that you can't name them all!' Flawed, as it was, Kate's logic about exactly what should and should not qualify as a planet is about as good what I have heard lately from some professional astronomers
Despite that, however, some of my brethren think that dwarf planetary bodies like Sedna shouldn't be termed planets
