I understand that the Sun's gravity keeps the Earth from flying off into outer space, but what's keeping the Earth from going into the Sun?

I'm an English Literature major, so math's not really my forté. Here they are:
#1: A regular incandescent lightbulb radiates most strongly at a wavelength of 3000 nm.
a) How hot is the filament? give your answer in Kelvins
b) In which part of the spectrum does it emit the most radiation: visible, or infrared (heat)?
#2: Use the orbit of one of Jupiter's large moons to calculate the mass of Jupiter. You will need to use the size of the orbit and orbital period. Using the formulas mass= 4 X Pi-squared/G (universal gravitational constant) X A-cubed/P-squared (A=orbit, P=orbital period) A has to be in meters and P has to be in seconds. What i've figured out so far for this one is that A= 422,000,000 meters, and P= 270,432 seconds, but take in mind my calculations may be incorrect.
I would appreciate any assistance, even if it just points me in the right direction for figuring these out, because right now, i really don't know know where to start.
Thanks!!!

if the Big Bang was real and we are living here just because some random stuff just smacked onto the earth, doesn't that mean that I can close my eyes, splatter paint on the ceiling and create a beautiful scene? no, all i will make is random colors. is the earth and the universe just random colors? no, it took planning and design. i want to know what you all think about this.

I have seen satellites come through my view when observing with a telescope, but they move way too fast for me to track.......so I am curious if I could somehow locate a Geosynchronous one and observe it. Has anyone ever pulled this off?

If a tree falls in a forest and no one or nothing is around to hear it or record it or anything, does it make a sound?

Unlike stars, planet reflects light. Therefore, they don't blink in the sky. To determine whether an object in the sky is a star, they blink in the sky. Do huge satellites blink in the sky? So how can we determine which is which in the sky? Furthermore, I have also seen two huge objects in the sky these days, may I know what these objects are? If both are planets, which is which and how can I differentiate them?

It is said that the people of the ancient times knew only planets upto Saturn. Uranus and Neptune were the planets discovered in the modern times. How did that happen?

Did you know that in 1991 an asteriod sailed past earth at a distance of only 170,000 kilometres away? (that is the cosmic equivalent of a bullet passing through one's sleve without touching the arm!) what would you do with your final day if the end was nigh?

if nasa was going to be sending a colony to a planet outside our solar system that had its own ecosystem which could be more or less dangerous then earth, but can sustain human beings, would go? This is if they had a way to preserve your age. I know this is far fetched by i think of this stuff all the time. And i would definitely go, even though it would mean goodbye to all my loved ones.

ive been thinking about this for a while, could it be that our earth is going to dry up like mars did..... dont you think that all this warming up and no more raining or snowing, ozon or things will let this poor earth dry?
do you know, all this makes me feel that, there might have been life on mars before earth and things like star gate could be true.... are these ideas to childish or do you think so too, or what?

Also, to follow up another question I asked regarding why life didnt somehow develop on other planets in our solar system; someone said that the environments did not support life. Well, why didnt they support a different type of lifeform that can tolerate those conditions?

The reason some people believe that is because there is no proof. I think they landed on the moon. Where else would they go??? I saw a spaceship blast off before and there mission was to go to the moon. Do people think they landed on Saturn and just told people they went to the moon???
