comment Why is 7 TeV considered as a big amount of energy?
1.15 x 10^11 is the design intensity per bunch, but it widely varies, though that's a faire estimate. 2808 comes from the spacing between the bunches (25ns) and the circumference of the machine.

comment Do the planets really orbit the Sun?
Thanks for that detailed answer. I fully agree one can use any reference frame, yet some are more "natural" than others. Your answer shows also that it is a complex matter and that the statement "planets orbit the barycenter" doesn't really explain anything per se.

comment Do the planets really orbit the Sun?
Your edit gives additional information. I conclude from it that saying that the earth orbits the barycenter of Sun-Jupiter (very close to the real barycenter of the solar system) is at best an anecdotal situation, there is no mathematical reasoning implying that the earth in the 3 body problem orbits the barycenter.
