Tau Ceti /epilson Eridani

[us.2u]

As these are the nearest solar stars like our sun; doe's anyone know if they have a planetary orbit around them? my guess is probably (no) & that we will never find ETI....us.2u

I'm pretty sure Proxima Centuari is the closest star to our Sun, and yes, it does have planets and they follow the same pattern as ours.

The key data on Epsilon Eridani:

epsilon Eridani b 0.86 MassJupiter, orbit 3.3 AU year 2502.1 ± 20.1 d

epsilon Eridani c?? 0.1 MassJupiter??, orbit 40 AU??, year 280 yr.?? [existence uncertain]

Nothing has yet been found for Tau Ceti.

 

C3H5... what is your source for Proxima Centauri planetary system? It is a runt of a star and thus far thought to be devoid of planets.

 

This is the 'bible' for all extra-solar planets:

Lmao, I'm just going with what my science teacher taught us....he says proxima centuari is the closest star to us, and has it's own planets, wow, guess not.

Well, Proxima (Alpha Centauri C) is the closest star, but it is unknown as to whether is has any planets. It is a small red dwarf that is part of the Alpha Centauri system which also includes Alpha Centauri A & B.

 

'A' is a yellow star of about the same mass as the sun, and could have planets in the habital zone, but it is unknown as to whether it does.

Ooooooh, alright, thanks.

Your teacher may well be right. It looks as if planet formation is a wholly natural and commonplace process. We know that there is a lot of dust and gas left around stars once they have formed. We also know it tends to gather together, quite rapidly, into lumps, then rubble, then asteroids (and comets) and planetesimals, and proto-planets, then planets. Proxima Centauri probably fits this picture too, but we don't know. We shall before long.

Thank you for that link Ophiolite it's a great source of info......it's a pity some other 'Astronomers' didn't stick to the topics of 'Astronomy' rather than pick fault, & doing so, making themselves a few light-years off topic...oh-welll WHATEVER...us.2u
