The main difference between stars and satellites is that stars are natural celestial bodies that are composed of gas while satellites are man-made objects that orbit the Earth and other planets. Stars are typically much larger than satellites and they can range from the size of a small planet to hundreds of times the size of our Sun. On the other hand most man-made satellites are usually smaller than a city block and are typically made of metal composite materials and plastic.
Stars have been and will continue to be an integral part of our universe as they provide light and warmth as well as a source of inspiration for many generations. On the other hand satellites are invaluable tools for communication navigation and exploration. They are also used for surveillance weather forecasting and to observe the Earth from space.
Astra is the Latin word for star. That is where the first part of the words astronomy and astrology comes from.

A good rule of thumb: Of the stars in the sky 1/2 are in double star systems Of the double stars in the sky 1/3 are in triple star systems Of the triple stars in the sky 1/4 are in quartenary systems ad infinitum It's not precisely correct, but uncertainty in these numbers are so large that it is within the error bars.
The first millennium began in 1 AD and ended 1000 AD. The second millennium began 1000 AD and ended 2000 AD. The third millennium (The current millennium) began 2000 AD and will end in 3000 AD.
|| since today is 2000 ad the time difference between 10000 ad and today is approx 8000 years || since the 12 constellations form the celestial sphere of 360 degree the difference between two consecutive const. is 30 degree approx since, the percesssion cycle repeats after every 26000 years > so every 26000/360=72 years(approx.) a 1 degree rotation takes place. >> so the total degree rotation taken place in 8000 years is >> 8000/72= 111 degree (approx.) > the constellation which is 111 degree apart from "aquarius" is "scorpius" or >>it can also be calculated by using (1.) since the difference between two consecutive constellation is 30 degree number of constellation between aquarius and const. is ... 111/30 = 3.7 (approx.) but since the aquarius side of celestial sphere contains less constellations than its right counterpart the difference is reduced to 3 which again gives us the answer as constellation "scorpius" thank you
Ad is higher than ac

what is that...
What is the difference between voluntary life insurance and life, ad/d?
AC is alternating current and AD is Anno Domini or after Christ.

AD means that Anno Domini , the year of lord and BD means that Before Christ

1,999 − 396 = 1,603 years. As both numbers are AD, treat as numbers rather than years. Subtract the lowest number from the highest number to get the answer in the number of years between the two dates.There is a difference if one date is BC and the other is AD. Which is another question.
DDR is not as fast ad the DDR2 ans that is the main difference.
