Answer 2

This site shows 61 and lists them
http://www.ifa.hawaii.edu/~sheppard/satellites/jupsatdata.html

Wikipedia says 63
http://en.wikipedia.org/wiki/Jupiter#Natural_satellites

There is no "surface" temperature on Jupiter (no real surface).

NASA's Jupiter page (they show 63 on the satellite page):
http://nssdc.gsfc.nasa.gov/planetary/planets/jupiterpage.html


PS:

sillycook77 gives a NASA Web Site that does, indeed, use the words "surface temperature",

Yet, this other page (also by NASA) states that there is no real surface and "The core temperature may be about 43,000 degrees F (24,000 degrees C) -- hotter than the surface of the sun."
http://www.nasa.gov/worldbook/jupiter_worldbook.html

I also looked at many other sites and it seems that nobody is really sure if there is a really solid surface that we would call a surface. There may be a slow transition from gaseous to liquid to metallic hydrogen as the pressure increases on the way down but, unlike water, these transitions are not clearcut in hydrogen.

However, if you are looking for an answer for homework, then use sillicook77's answer.

Answer 3

At least 61 moons and a mean surface temperature of 14.85 - 19.85 C (58.73 - 67.73° F).

Answer 4

At the moment, the moons have bypassed thirty and are multiplying rapidly. This is becaus eJupiter's gravity is so large that it draws in asteroids from the nearby asteroid belt.
