How Many Regions Are There In The Solar System?

1. How Many Regions Are There In The Solar System? 11

2. What Are The Regions The Regions are: • Asteroid Belt • Oort Cloud • Planetary Rings • Scattered Disc • Ecliptic Plane • Interstellar Wind • Heliosphere

3. Asteroid Belt • Is composed of 200 objects that is over 100km (60 miles). • It lies between Mars and Jupiter • Asteroids are rich in minerals, the estimated wealth of the asteroid belt is 100 billion dollars for every person on Earth today • The average surface temperature of an asteroid is -73C (-100F) www.universetoday.com

4. Oort Cloud • Is the closest to the sun • Objects in the Oort cloud are largely composed of ices, such as water, ammonia, and methane. • Astronomers conjecture that the matter composing the Oort cloud formed closer to the Sun and was scattered far into space by the gravitational effects. www.dailygalaxy.com

5. Planetary Rings • The most notable planetary rings in the Solar System are those around Saturn • but the other three gas giants (Jupiter, Uranus, and Neptune) also possess ring systems • On 26 March 2014 was announced the discovery of rings around the minor planet Chariklo during the observation of a stellar occultation on 3 June 2013. www.posterlovers.com

6. Scattered Disc • The scattered disc (or scattered disk) is a distant region of the Solar System that is sparsely populated by icy minor planets, a subset of the broader family of trans-Neptunian objects. • These extreme orbits are believed to be the result of gravitational "scattering" by the gas giants, and the objects continue to be subject to perturbation by the planet Neptune. www.universetoday.com

7. Ecilptic Plane • The ecliptic is the apparent path of the Sun on the celestial sphere, and is the basis for the ecliptic coordinate system. • It also refers to the plane of this path, which is coplanar with both the orbit of the Earth around the Sun and the apparent orbit of the Sun around the Earth. www.herongyang.com

8. Interstellar Wind • In astronomy, the interstellar medium (or ISM) is the matter that exists in the space between the star systems in a galaxy. • This matter includes gas in ionic, atomic, and molecular form, dust, and cosmic rays. • It fills interstellar space and blends smoothly into the surrounding intergalactic space. • The energy that occupies the same volume, in the form of electromagnetic radiation, is the interstellar radiation field. www.redshift-live.com

9. Heliosphere • The heliosphere is a vast region of space surrounding the Sun, a sort of bubble filled by the interplanetary medium and extending well beyond the orbit of Pluto. • Plasma "blown" out from the Sun, known as the solar wind, creates and maintains this bubble against the outside pressure of the interstellar medium, the hydrogen and helium gas that permeates our galaxy. solarsystem.nasa.gov
