ORR (#5)


Stardust Discovered in Far-Off Planetary Systems



They are a lot of planets know already. There are at about 700 hundred different planets that we know. People know that these are not all planets in the universe. There are also planets that are not lightning anymore but you can still see them. (I think that that is really cool.) We can't see them because there are so far away that it takes the light if that planet that we see at about a million years (depends on the distance of the planet to earth). And now they discovered a new Stardust in the Far-Off Planetary System. In the Astropysical Institute a German Astronomer saw that there are between to different planets remnants of that planet. That means that there this planet lost parts which are now, or maybe that happened hundred thousand years ago, still floating between or around these two planets. The gravity of these two planets force the dust to stay with them wherever they go. In the article it says that these two planets might have collided and that some parts broke off so that there are floating around them. I think that this is pretty cool because now these two planets who probably crashed with high speed into each other are now pulling themselves so that they won't lose themselves anymore. With that pull they also pull the remnants which are in between. Also it is interesting that we can actually see that although they are so far away.
