Document Summary
Lecture the geography of planets and moons. The sun: the sun is a fairly typical star. The equatorial circumference of the sun is 4. 3 million kilometers (109x earth) it would take 1. 3 million earths to fill the same space as the sun. Converts hydrogen into helium through nuclear fusion, a process that emits massive amounts of ultraviolet radiation. The sun ejects a constant stream of sub-atomic particles these make up solar winds which carry throughout the solar system. These winds contacting earth"s magnetic sphere create the northern. Strong solar winds can disrupt satellites in earth"s orbit as well as earth based electronics. The sun also emits solar flares, which are large releases of x-ray radiation and energy from the sun"s outer layers and travel the speed of light in all directions into the solar system. Solar flare single beam emitted from sun which may or may not hit a planetary body.
