The Universe
Age of solar system---scientists have determined that the Solar System is 4.6 billion years old.
Nebular hypothesis---In cosmogony, the nebular hypothesis is the most widely accepted model explaining the formation and evolution of the Solar System.
heliocentric vs geocentric---The heliocentric model, which means sun centered, gradually replaced the geocentric model./---In astronomy, the geocentric model (also known as geocentrism, or the Ptolemaic system), is a description of the cosmos where Earth is at the orbital center of all celestial bodies.
inner planets (characteristics and order)---
The inner planets are the planets in the inner part of the Solar System that orbit closest to the sun. The 4 inner planets are Mercury, Venus, Earth, and Mars.
outer planets (characteristics and order)---stronomers have divided the eight planets of our solar system into the inner planets and the outer planets. The 4 inner planets are the closest to the Sun, and the outer planets are the other four – Jupiter, Saturn, Uranus, and Neptune.
asteroids, meteors, comets (info and location)---
Asteroids are rocky fragments left over from the formation of the solar system about 4.6 billion years ago./A meteoroid is a small rocky or metallic body travelling through space/A comet is an icy small Solar System body that, when passing close to the Sun, heats up and begins to outgas, displaying a visible atmosphere or coma, and sometimes also a tail./
milky way---The Milky Way is the galaxy that contains our Solar System.
Sun---The Sun is the star at the center of the Solar System.
solar flare, EMP, what fuels the sun---The degree of Solar flare effects depend on the strength of the flare and if strong enough, the solar impact can effect everything from the earths magnetic field, triggering natural disasters, to impacting individual brian activity.
