Externet Posted April 10, 2012 Posted April 10, 2012 If a star, or a sun, 'burns/converts' matter into energy, chances are the homogeneity of its matter among its active surface is not, as flares appear in an area and later on another, as a non uniform surface 'burning' Is our sun propelled (transported, pushed) randomly in space by the energy flares it emits as to move towards opposite the random significant flares ?
Janus Posted April 10, 2012 Posted April 10, 2012 A typical CME has a mass of ~1.6e12 kg. If you compare this to the mass of the Sun, 2e30 kg, it turns out that even 1,000,0000 CMEs, all pointing the same direction would only change the Sun's velocity by ~0.4 nanometers/sec. So I'd say that CME's have no measurable effect on the Sun's motion. 2

I guess it would, by a tiny amount. Depends though, sometimes, if the flare caused the internal forces/turbulance to switch direction, it might propel it toward the same direction as the flare goes. As the sun is not really a singular ball, it is really tons of stuff together that end up looking like a sphere from a distance. THere is tornados, hurricanes all over it, so a lot of the motion the stuff in those hurricanes are doing could "eat up" the opposition direction force exerted by the flare. -2

Newton's laws of motion still apply. Internal forces will not cause or counter propulsion.
