Small+Bodies

==__** small bodies **__ ==  Comets, otherwise known as Dirty Snowballs are balls made entirely out of ice ,dust,and fragments of rock. Astronomers believe that comets are made of the very material that formed the solar system. Comets are the only small bodies that can be seen by the naked eye from Earth.

The first small body is: Halley's Comet

It was named after Edmond Halley who predicted it would return in 1758. Sorry for him he died before it returned. This popular comets orbit takes 76 years. The last time it came was in 1986, and it is predicted to come again in 2062. So unless you decide to die from skin cancer...or some other weird illness, you might be able to see it,actually you probably wont.You will be so old that your grandkids will have to describe it to you!!!..but thats ok becuase in the future i bet they'll have medicane for that. Here is a link that will help explain more:[|Halley's comet]

Commet Shoemaker-Levy 9 was discovered by Eugene and Carolyn Shoemaker and David Levy in 1993. It is found on a path near Jupiter. When ever SL 9 went by Jupiters Roche limit it broke into 21 pieces. Here is a picture of the comet. Next is the Kuiper belt and Oort cloud is the next SMALL BODY. It is outside the orbit of Neptune's orbit. It contains many icey pieces in it. Eventualy it is going to hit Neptune sending it out of the solar system. here is a picture.

Sedna is next on our list of the 12 small bodies. This body is the furthest away from the sun. It is 3 times further then pluto an X planet. Speaking of Pluto Sedna is only a tid bit smaller then it. It takes 10500 years to orbit the sun. It is outside the kupiter belt and inside the Oort cloud.



Asteroids are very well known, but I'll tell you about them again. Pallas, Vesta, and Juno were among the first dicovered. Many thousands of asteriods have been found since then.  Mars and Jupiter is where the next asteriod 951 Gaspra orbits. Neujmin discovered it. The surface is covered in impact craters, 600 to be spacific.

The interplanetary medium is the material which fills the solar system and through which all the larger solar system bodies such as planets, asteriods, and comets move from the solar winds. Interplanetary medium is approxamatley 100,000 K, and its density is very low at about five particles per cubic centimeter in the vacinity of the earth; it decreases with increasing distance from the sun, in proportion to the universe square of the distance. It's plasma is also responsible for the strength of the suns magnetic field at the orbit of the earth.

aurora borealis ( also known as the polar lights) is an amazing ray of rainbow like colors, that useally appears at night. But sad to say it's ONLY SEEN IN SEPTEMBER-OCTOBER,AND MARCH- APRL. I wish i could see it all the time
