Question A question for you, how close are stars with planets around them?

Got a question for you star watching folks, and I need it how do I put it lay man terms. Dan J. and I were wanted to know how we come in find planets around them.

National Geographic on TV had one planet that had an orbit kinda like the Red Star not as bad as it.

As far as I know the nearest star is Proxima Centauri @ 4.24 light years.

The nearest with planet(s) is Epsilon Eridani @ 10.52 light years (1 definite and 1 possible).

Gliese 876 has 3 confirmed planets and is 15.34 light years distant.

Ginny, could you try and re-phrase your question please?

Are you after a list of known extra-solar planets and how far away they are?

Or, are you interested in how we find them?

A bit of both.

Also what kind of life would you find there?

This is one of the major exoplanet resources out there, and this is a more basic introduction. Here is a form where you can query the catalog for details of exoplanets, but that probably won't be immediately useful to you...

Here's WIKI's list - go to the star data for distances to these systems from Earth.

To your second question, Ginny: Alien life! If there's any at all. As a lot of them seem to be Jovians way too close to their suns if I remember right.

Ah, but those are just the easiest ones to find! There's plenty of rocky dirtballs out there for terrestrial-style lifeforms.

Alien life? On planets like our own, it'll be the same, but different. There'll be similar things. Plants, flowers, scents. Wings. Limbs. Symmetry. Scales. Hair. Respiration. Predation. All the fun things that make up our own ecology - evolution will drive species into occupying empty niches the same way everywhere. But the root ingredients may be very, very different in terms of the chemistry and genetics.
