Dont worry your not doing my home work. My son who is three is asking about this after going to the space center. He is really into space right now and has asked if he could ask this question here. Please be nice as his nephews who are 7 & 9 will also be reading this. Thanks

366,242 1/2 times.
(a) Once a day for 365 days per year = 365,000
(b) Once a year for the annual revolution around the sun = 1,000
(c) 97 times every 400 years to account for leap years. There is not exactly one leap year every 4 years. So, (1000/400) times 97 = 242.5
When you add up (a), (b) and (c) you get 366,242 1/2.
Good question.

Since the Earth rotates 365 1/4 times per year, in 1000 years it would rotate 365,250 times, give or take a few rotations.
365.25 x 1000 = 365,250

Are you talking about rotating as in the Earth spinning, or the Earth revolving around the sun?
The Earth does one rotation per day. There are 365.25 days per year, so it will do 365,250 rotations in 1000 years.
The Earth takes one year to revolve around the Sun. Thus, it will revolve around the Sun 1000 times. Why is this so convenient? Because we chose our time system to match with Earth's movements! The seasons change as we revolve around the Sun since different parts of the Earth get different amounts of sunlight.
That is really great that he is so interested. When I was his age I was constantly reading things about space. Now i'm an aerospace engineer!

Well, one rotation is one day. In the average one year has 365.25 days, hence the leap years. So, in 1000 years you have 365.25*1000 days. Thats 365250 rotations.
As you know, the 365.25 is not 100% exact, the actual number is 365.242375. If you want to know it very very acurate you have to calculate it with this number.

HERE 1 revolution= 1 day 365.25=1 yearmultiply by 1000=365,250

365 days times 1,000 years
365,000 times
Oh yeah there will be some leap years thrown in there sorry. So maybe the 1st guy is right.

solar days per tropical year 365.2422
sidereal days per tropical year 366.2422
one thousand tropical years is 365242.2 solar days
one thousand tropical years is 366242.2 sidereal days
