last planetary alignment.
it depends on how the earth is facing and bc of the galaxy.
Eratosthenes estimated the size of Earth in 240 BC by comparing the angles of the shadows cast by sticks in two different cities on the same day. By calculating the difference in the angles, he was able to determine the circumference of the Earth with impressive accuracy for the time period.
Earth's rate of revolution about the sun has changed very little over the past few million years. It is not likely to have changed significantly in several billion years. There is, however, evidence some of the planets have migrated inward and outward a bit since the time of their formation 4.5 billion years ago.
Sometime between 384 BC (when he was born) and - 322 BC (when he died). Most assuredly he was not the first to think that everything revolved around him (or his neighborhood)!
The sun is not affected by the nuclear power generated on Earth. The nuclear reactions that power the sun are happening in its core, while nuclear power plants on Earth use fission reactions that do not have the ability to impact the sun's nuclear fusion process.

23 BC, 765 AD, and 3012
1000 B.C. was roughly 3012 years ago... There is no year 0 in the Gregorian or Julian calendar don't listen to the people who are including a year 0, 3012 is the correct answer. Add "the current year" + "BC year" - 1 year, so for you case, 2013 + 1000 -1 = 3012 yrs ago was 1000 BC BC stands for Birth of Christ (some people wrongly say it Before Christ)
