Our solar System. The Nebular theory. The Nebular Theory is based off of observations of objects, such as comets, asteroids, shape and size of our planets in our solar systems as well as stars outside our solar system.
Our solar System
The ice on Mar’s poles is a carbon dioxide ice not H2O ice.
Enceladus is similar to Europa in that there could be liquid oceans under the ice heated by the gravity pulsing creating heat.
Crack in the ice and gysers support the idea of aubunant surface liquid water.
Neptune has a Great Dark Spot, similar to Jupiter’s Great Red Spot.
Average distance from Sun- 3.8 billion miles
Diameter- 1,432 miles
5 Moon- Charon (Diameter of 730 miles), Nix , Hydra, Vulcan and Kerberos. (Ask who voted to select the last two names of Pluto’s moons)
Atmosphere- 99.97% Nitrogen
Rotation= 6.38 days
Revolution= 248.6 years
Gravity- 1/8 that of Earth
Orbit- Pluto has a more elliptical and titled orbit, one of the reasons its lost identification as a planet. This tilted orbit sometimes allows it to be closer to the sun than Neptune, making Neptune further than Pluto.

Asteroids- large pieces of rocky debris, some larger than our moon.
Most asteroids in our solar system are located in the asteroid belt between Mars and Jupiter.
Asteroids do not have a specific orbit, they cluster in the belt and are continuously knocked out or pulled in my Jupiter.
Meteors and Meteorites:
Meteors- pieces of rock that burn up in our atmosphere. (shooting star)
Meteorite- pieces of rock that survive burning up in our atmosphere and land on the surface of the Earth.
Comets- balls of ice and dust in a specific orbit in space.
Kuiper Belt and Orrt Clouds-these are two areas at the edge of our solar system where comets are located until knocked into a new, closer orbit.
