here are some interesting questions we got at regionals: what color is the sun? what temperature is the sun? (the answers were in kelvin) which way does the earth rotate (clockwise or counter clockwise)? Why can't Venus support life? I also had to graph the cross section of jupiter. <---if that doesnt make sence then dont ask me to explain it

Does anyone know the conversion for miles to astronomical units vise versa and so on and so forth.

yeah, and light years, austronomical units, megaparsec, miles, and kilometers
me and Tying need to be able to translate all of these to each other, because it could appear in any of these
thanks : D

One astronomical unit (au) is the mean (average) distance from Earth to the Sun if I remember correctly. Therefore, you could convert from au to kilometers and miles and vice versa so long as you know how far away the Earth is from the Sun in the units you want to convert to. In answer to another question, one light year is the distance that light can travel in a year.

Yeah, space scientist is correct. One AU is 149,598,000 kilometers or 92,955,887.6 miles. At any given point the Earth is approx. 1 AU away from the sun, although it differs for solstices and equinoxes, etc.

LOL!

There was one question on our test that said:
Are the number of degrees in a circle based on objects in the solar system?
We put no, because we read that 360 was chosen since it more factors than 100. However, when we looked it up later, it said one theory was (something like) since there were 365 days in a year, they approximated the # of deg. in a circle with the times they saw objects in the sky appear again.

I didn't get the test back, but any ideas?

I won a 5th place medal in regionals, even when me and my partner completly guessed. For example, we didn't know one question at all, so we put down hypothesis as the answer. :mrgreen:
