Super Nova



Solar Nebula



Particles began to stick together to form clumps 





Bigger clumps formed planets/moons

Center cloud


Earth formed



Only rocky material could stand heat

Icy matter


Formed in the outer regions



Giant planets like Jupiter was formed

The center eventually got so hot that it became a star, the Sun, and blew most of the gas and dust of the new solar system with a strong stellar wind

Scientists have found that the solar system is about 4600 million years old!



An exoplanet or extrasolar planet is a planet that orbits a star other than the Sun, a stellar remnant, or a brown dwarf. Nearly
2000 exoplanets have been discovered (1933 planets in
1223 planetary systems including 484 multiple planetary systems as of 18 July 2015).

Number of extrasolar planet discoveries per year through September 2014, with colors indicating method of detection:

radial velocity -Blue transit –green timing -yellow direct imaging -Red microlensing -Orange
