Solar Nebula Theory: The contemporary theory most formally accepted by astronomers is the Super Nova Theory. This is the theory that the explosion of a nearby star, Super Nova, caused a cloud of gas and dust to be disturbed, forming our solar system. The theory states that the explosion forced waves in space, squeezing the cloud, causing it to collapse. The cloud had a dense, hot center, with a disk of gas and dust surrounding it. As the disk became thinner, the particles formed clumps and eventually formed planets or moons. Near the center, only rocky material could stand the heat, so planets such as Earth settled in the inner regions. The sun drove away the icy, gassy material, and those planets, such as Jupiter, settled in the outer regions. As the cloud continued to fall in, the center became so hot it formed a star, the sun. Improvements in telescopes and observational techniques, astronomers have been able to detect Jupiter

Unformatted text preview: sized planets surrounding other stars proving there are other solar systems. These planets are commonly referred to ashot Jupiters , which are planets that are usually the size of Jupiter, or larger; but are sometimes as close to the star as Mercury is to the sun. The reason the Solar Nebula Theory is disproved by these solar systems is because the theory states that the reason the inner planets are terrestrial, (rocky) is because the sun drove away all the light gasses like Jupiter. But these solar systems show planets like Jupiter close to their star, contradicting the contemporary thought of how our solar system formed.
