Feb 17, 2023 at 1:45 comment added AtmosphericPrisonEscape @RichardBradWatsonII Are you interested in that specific number that Zxyrra quoted, or would you be happy with other references for the age of the solar system (they do cluster around a value of 4567 Myrs old, but depending on the method, the absolute uncertainties can reach a few Myrs). The question is a few years old, so I am asking, at the risk that OP is not active any more.

Jan 24, 2017 at 12:30 comment added Adwaenyth This question is a little broad... first you'd have to define from which moment on you would want to speak of earth. A chunk of debris flying through a protoplanetary disk? Then you'd have to calculate how long ago that has been? Then you'd have to check if there have been any significant orbit changes to earth orbit? All of these are quite interesting questions, the actual number of revolutions around the sun is actually a rather uninteresting result of these.

Jan 22, 2017 at 9:19 comment added userLTK The Quora answer isn't reputable. It assumes no change in the number of hours in a year and the writer is only making a point on the change in the length of a day. It's a valid point to make because the days have grown longer, but it fails to answer your question. I think the Reddit answer comes closest to a good answer, but there's still some uncertainty, especially very early.
