ive just realized something about our current ways of looking for exoplanets. usually large observatories look at stars for long periods of time and wait for the planet to pass by the sun so we cant see it, and if that happens we know there is a planet there.

but think about how many flaws that has. it could be a cloudy night and you could compeltely miss it.

also, the planets have to be fairly large in comparison to their star in order for it to completely cover up the light coming from it. that means our search for an earth like planet is never going to work because all we can find are gas giants and rarely some massive solid planets.

and the biggest one. it only works if the earth, the star, and the orbit of the planet are in one plane. if their not all exactly in a line then the planet will never cross infront of the star and well never see it.

theres got to be a better way...are there any other techniques out there?

Help me to solve this problem. "Calculate the ratio of gravitational force of the moon to the gravitational force of the earth, by taking the mass of the earth to be 6.0x10^24 kg , radius of earth as 6.4x10^6 m , the mass of the moon as 7.4x10^22 kg , and radius of the moon as 1.7x10^6 m. "

Whatever happened to TracyTerry?
I'm sure you all remember her... Silly, pointless questions...
Did she get kicked out?
On a Sabbatical?
Frontal lobotomy?

I know... Wrong forum.
I'm just curious as to what may have happened... I guess I kinda miss those goofy questions...

About two years ago I began learning about black holes in science. To be quite frank, I just don't get it... it doesn't make any sense to me.

Can someone explain the concept of black holes in "caveman" terms because the whole sucking light in, nothing escaping thing has me confused.

Thanks!

Pluto's diameter is approximately 2370 km, and the diameter of its satellite Charon is 1250 km. Although the distance varies, they are often about 1.95×104 km apart, center-to-center.
Assuming that both Pluto and Charon have the same composition and hence the same average density, find the location of the center of mass of this system relative to the center of Pluto.
