I assure you, our sun is considered a star.

[Kaezion]

yes, you are right. my mistake.

New planets are always forming and one or two could be grabbed by the sun's gravity, though this is very unlikely. The current planets (to our knowledge) formed from the original nebula and were therefore already in an orbit around the sun when it formed. The distance to other stars is enormous also, so a planet isn't likely to be caught anytime soon. In fact, the distance is so large that if the length of my school's football field was the distance between Uranus and the sun (I live in Maryland), the nearest star would be in Texas.

thats y its so f in hot here

As we all know:

1 A.U. = 150,000,000 KM (Average of earths closet distance to the sun, 148,000,000 KM and its farthest distance from the sun, 152,000,000.)

If we could travel at the speed of 1 A.U. per a second (500x the speed of light) we would fly through the Terrestrial planets within seconds. When we reached the Jovian they would spread out about 3-8 seconds. The total time it would take to reach Pluto (Planet X) is about 40 seconds.


I just thought it was interesting to share...

------------------

According to the big bang theory, the sun "exploded" into a star. Is it possible the sun is still expanding? Can the sun turn into a black hole eventually? If so, when would this happen? EDIT- Ive read that the sun is at its final stage now.

-------------------

Pluto, is not considered a planet but rather a moon. This could be proven so because Pluto crosses Neptunes orbit every so often. This could be because Pluto was sent so out of "whack" that it is still "calibrating" (sp?) itself.

-----------------

Could our universe get more planets? All of the planets orbit with the suns gravity. What are the chances of the sun grabbing in another celestial body and making it become a planet, much like what could have happened to Pluto?


--------------------

To travel faster than the speed of light you would need more energy than the universe contains. So no, you can't travel at 1 A.U per second, you can't travel faster than light.

Maybe you should have a closer look at the big bang theory. The sun didn't do any exploding, that would be the universe. The universe didn't even explode, it expanded, creating time and space. The matter that came out was either hydrogen, helium and lithium. A matter abnormality clumped together and lit up into a nuclear fusion, becoming our Sun.

I don't get the next bit.

Again, get your facts right, the theories you have got are very old. The sun is not the centre of the universe, it is the centre of the solar system, consisting of nine offical planets. It is part of the universe, with many, possible infinate, stars (like the sun) and planets. It is possible that the Sun could trap a passing rock which could be big enough to be classed as a planet. I don't know about a gas giant, but it is possible.

Oh and Sedna is part of the Kupar belt, an astroid belt beyond Pluto.
