Is the sun close to earth?
The sun is approximately 1 AU (149,597,870.7 km. or 92,955,807.27 mi.) from the Earth. Compared to Mercury, the Earth isn't that close to the Sun, but compared to Jupiter or Saturn, it is pretty close.
That's a fine example of a question to which you can get different answers from
different people, because the criteria used to define it are so arbitrary.
"Close" is a concept that has different meanings in different contexts ... just as
Prof. Einstein so brilliantly expounded in his work on Relativity..
If you live in Chicago, then the sun is 270 thousand times farther from you than Des Moines is,
but 270,000 times closer to you than the next nearest star is.
So in the end, it really depends on what you call "close".
The earth travels around the sun in an orbit, because of the Continuity Condition . the balance of the centripetal force vp/r versus the centrifugal force cDel.P = -cp/r cos(PR). The centrifugal force is the Divergence of the vector energy cmV, the Momentum energy. The momentum energy cP is aka the inertia or "Dark Energy". W = --mu/r + cP and Force =XW = [d/dr, Del][ -mu/r, cP] = [vp/r - cDel.P, cdP/dr - Del…
Perigee, "peri-" for close, and "gee" as an abbreviation for the gravity of the Earth. The point at which the Moon is farthest away is called "apogee". The points in Earth's orbit around the Sun when the Earth is closest and farthest are perihelion and aphelion, from the Greek word "Helios" for the Sun.
