Are there new planets being formed in space?
Question Date: 2005-12-08
Answer 1:

Yes. Scientists have observed a number of star systems in the process of forming, and they have also seen the disks of matter that will one day be planets. The NASA has a telescope named Spitzer Space Telescope which has spotted the very beginnings of what might become planets.

Another astronomer from the Harvard-Smithsonian Center for Astrophysics in Cambridge has discovered hot extra solar (outside our Solar System) planets. He things that these gassy giants could even represent a new breed of planets.

There are several new discoveries constantly going on that reflect the evolution of the Universe. Not only new planets are being formed, but also stars and galaxies.

Answer 2:

That is a question scientists are still trying to answer!As you know, there are nine planets in our solar system now. The planet that is farthest from the Sun is Pluto. Beyond Pluto, there are many objects smaller than Pluto that also revolves around the Sun. However, in 2003, scientists discovered a new object further away from the Sun, which is bigger than Pluto. Scientists have not decided if this object is actually a planet. A final decision is expected by the end of this year. This new planet may be named Xena; however, this has also not been decided yet.
