MERCURy help?

Question

what is the....
1.Size
2.Distance from the sun
3.Atmpsphere like
4.Length of its day and a year
5.Density

And what web site did you get the info from???

And Dont Give just a website
like
Wikipedia.com
i know about that all ready and have looked at the sit an dreally couldnt find anything.

Answer 1

My Dear, you'll feel much better about yourself if you do your own homework.

Try going to your local library. If you can't find what you're looking for ask the Librarian for help.

If you need help UNDERSTANDING something you've read, please post again and I'm sure everyone will be happy to help you.

Answer 3

Look at the table of information on the right hand side of the page for Mercury on Wikipedia. It lists every fact you're looking for, and THEN some. There's not even any need to read the long and interesting article if all you want to do is fill in the blanks on your homework before going out on Fri night.....

Size: Is listed under physical char. as "mean radius"

Distance from Sun: Listed under orbital char. - semi-major axis is probably a good "average" answer.

Atmosphere: listed under "atmosphere" as 'trace' meaning not really one to speak of....

The length of day and year are under orbital char. as synodic period and orbital period.

Density is listed under physical char. as "mean density"

Answer 4

wiki tells you everything !!!!!!!!!!!!!!!!!!!!!!!!!.......

you should try reading it again instead of asking for people's "opinions" here.

they can be wrong
wiki is monitored voted on and is comprised of FACT. not opinion.

http://en.wikipedia.org/wiki/Mercury_%28planet%29

how can you NOT find any info on mercury there?

1.size? do you mean mass, volume, radius, or surface area. ITS ALL ON WIKI!!!!

2. the Semi-major axis is the distance from the sun. wiki says its 57,909,068 km = 35,983,026.6 miles

3. a quote from wiki....... imagine that.
"Mercury is too small for its gravity to retain any significant atmosphere over long periods of time; however, it does have a tenuous atmosphere containing hydrogen, helium, oxygen, sodium, calcium and potassium"

4.
A: Orbital period = (its year) = 87.969098 days
B: Sidereal rotation period = (its day) 58.646 days

5. Mean density 5.427 g/cm squared


BTW!!! ALL YOUR QUESTIONS WHERE ANSWERED THROUGH WIKI...............
