Document Summary
The sun is the largest object in the solar system. Equatorial circumference = 4. 3 million kms (109x earth: mean radius = 430,000 kms, diameter = 840,000 kms, h & he fusion of hydrogen and helium, wi(cid:374)ds + earth(cid:859)s (cid:373)ag(cid:374)eti(cid:272) sphere = norther(cid:374) lights. Volume = 1. 3 million earths (cid:858)solar wi(cid:374)ds(cid:859) - constant stream of sub-atomic particles (creates the northern lights) Solar flares - large releases of x-ray radiation and energy, speed of light in all directions into the solar system sun gives off all radiation (imagine sun burping x-rays) Coronal mass ejections - large masses of particles ejected in a single direction, slower than the speed of light similar to flares but they are solid particles that are projected out (imagine sun burping our large particles) The sun is the center part and the core of the solar system, everything revolves around it. It has achieved hydrostatic equilibrium (so much gravity that the orbit is a circle)
