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 )

  • Its huge gravity holds the planets in place

  • The planets all revolve around the Sun

  • Moons rotate around their parent planet

  • 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'

  • TRAVEL INFORMATION From the Earth You can sometimes spot the planets in the night sky from Earth

    Solar Views: 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

    Views of the Solar System: Jupiter
    Views, animations, general information and data of the planet and its satellites.

  • Jupiter Then felt I like some watcher of the skies when a new planet swims into his ken

  • Spencer, $25.95 Hardcover - 1995 , by David Levy, $18.17 Hardcover - 1995 , by Seymour Jupiter Simon, $11.20 Hardcover - 1998 , by Reta Beebe, $29.95 Hardcover - 1997 Jupiter is the fifth planet from the Sun and is the largest one in the solar system

  • It also contains more matter than all of the other planets combined

  • (The rings were discovered in 1979 by Voyager 1.) The atmosphere is very deep, perhaps comprising the whole planet, and is somewhat like the Sun

  • The rings are very tenuous and are composed of dust particles kicked up as interplanetary meteoroids smash into Jupiter's four small inner moons, and

  • It is formed as fine particles of dust from the main ring's inner boundary 'bloom' outward as they fall toward the planet

  • Jupiter's rings and moons exist within an intense radiation belt of electrons and ions trapped in the planet's magnetic field

  • This true color mosaic of Jupiter was constructed from images taken by the Cassini spacecraft on December 29, 2000, during its closest approach to the giant planet at a distance of approximately 10 million kilometers (6.2 million miles)

  • 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

    Your Weight on Other Worlds
    From the Exploratorium, an interactive calculator that will determine a person's
    weight on another planet.

  • You can click on the images of the planets to get more information about them from Bill Arnett's incredible web site

THE SUN Your weight is A WHITE DWARF Your weight is A NEUTRON STAR Your weight is Mass and Weight Before we get into the subject of gravity and how it acts, it's important to understand the difference between weight and mass

  • 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

    Walk the Solar System
    JavaScript calculator of sizes and distances of solar system bodies for making
    a scale model.

  • Notice that the distances and sizes of the planets will automatically fill in

  • To mark a planet's place you can use a piece of paper on a post that you stick into the ground, or you can use a flag, or even a person

  • You can click on the names of the planets and satellites to go the the web site page about them

  • If you'd like to see the satellites of the planets as well, for a much more extensive page (and a longer download time too!) One of the most exciting excercises I ever did as a kid was to make a scale model of the Solar System

  • Most of the pictures in my books made the distance between planets seem small and easy to travel

  • The models they displayed usually had the sizes of the planets to scale, but the distances between them were a completly different scale, giving the impression of a rather close-knit family

  • I also calculated the sizes that I should make the dots that represented the planets

  • I found that even the largest planet, Jupiter, should have a spot size smaller than 1/8 inch

  • The other planets, especially the small rocky inner planets, would be virtually invisible dust spots

    Astronomy for Kids: Uranus
    Offers details about the location, the visibility, the size and the rings of this

  • ....and supervised adults Uranus Uranus A Seemingly Featureless Planet Uranus Facts Distance from Sun Approximately 1.8 billion miles Number of Moons At least 29 Diameter Approximately 32, 000 miles Length of Day 17 Earth hours Length of Year 84 Earth years Name Ancient Greek god

  • The giant planet, which is another of the gas giants of our solar system, is more than twice as far away from the Sun as Saturn

  • The bland face that the planet shows to us humans hides high speed winds, the fact that Uranus is tilted on its side and a very mysterious weather system

  • Although the Voyager spacecraft visited the seventh planet during its epic journey through our solar system, the pictures it sent back from Uranus were somewhat disappointing

  • We had hoped to see some color bands like there are on Jupiter or at least some faint colors, but the face the planet presents doesn't seem to vary, regardless of how close or far away from it you are

  • The planet does contain some rocky material, but the planet is almost all gas, with the outer layer of methane providing the blue color we see in the picture at the right

  • The pale blue image we see of Uranus hides the fact that the surface of the planet is swept by 'winds' moving along at several hundred miles per hour


    Astronomy for Kids: Jupiter
    Provides details about its location, its visibility from Earth as well as data
    related to its size and its moons.

  • ....and supervised adults Jupiter Jupiter King of the Planets Jupiter Facts Distance from Sun Approximately 466 million miles Number of Moons At least 63 Diameter 85788 miles Length of Day 10 Earth hours Length of Year 12 Earth years Name Comes from the Roman king of the gods

  • Visited by Pioneer 11, Viking, Galileo and others The fifth planet in our solar system is also the largest planet in our system, both in size and mass

  • Jupiter's diameter of over 85, 000 miles is almost twelve times that of Earth and its mass is well over twice as much as all the rest of the planets put together

  • These facts make it appropriate that the planet is named after the king of all the other gods in ancient Roman mythology

  • Jupiter is also the first of the gas planets in our system

  • A gas planet is one that does not have a solid surface like Earth

  • Instead, you can think of Jupiter, as well as the rest of the gas planets, as being a giant ball of mostly hydrogen and helium

  • Scientists believe that Jupiter has a small rocky core at its center, but even the core of this giant planet is much larger than our Earth

  • Jupiter's size not only makes it the largest planet in our solar system, it has also helped us explore the outer planets

    How Big is the Solar System
    Also known as "The Earth as a Peppercorn." A scale model of the solar system.

  • Both the relative size and spacing of the planets are demonstrated in this outdoor exercise, using a mere peppercorn to represent the size of the Earth

  • Image of the planets courtesy of Can you picture the dimensions of the solar system? Probably not, for they are of an order so amazing that it is difficult either to realize or to show them

  • You may have seen a diagram of the Sun and planets, in a book

  • But even the largest of such models--such as those that cover the ceilings of the Hayden Planetarium in New York and the Morehead Planetarium at Chapel Hill-are far too small

  • They omit the three outermost planets, yet still cannot show the remaining ones far enough apart

  • The fact is that the planets are mighty small and the distances between them are almost ridiculously large

  • To make any representation whose scale is true for the planets sizes and distances, we must go outdoors

  • There is one other party that may profitably take the planet-walk, and that is yourself, alone

  • They are: -any ball, diameter 8.00 inches -a pinhead, diameter 0.03 inch -a peppercorn, diameter 0.08 inch -a second peppercorn -a second pinhead -a chestnut or a pecan, diameter 0.90 inch -a hazelnut or an acorn, diameter 0.70 inch -a peanut or coffeebean, diameter 0.30 inch -a second peanut or coffeebean - a third pinhead (or smaller, since Pluto is the smallest planet) You may suspect it is easier to search out pebbles of the right sizes
