What magnification would a telescope need to be to see the nearest star?

What magnification would a telescope need to be to see the nearest star? I don't mean as a bright white dot, but actually see the round shape.What magnification would a telescope need to be to see the nearest star?Zero magnification, the sun is the nearest star and you can see its round shape without optics.What magnification would a telescope need to be to see the nearest star?
The only telescope that has been able to image the disc of a star is the Hubble. (..http://hubblesite.org/newscenter/archive鈥?/a>

No amateur telescope you can buy has enough resolving power to allow you to see the disc of even the nearest star (..the sun being the exception of course..)What magnification would a telescope need to be to see the nearest star?As little as .05X or even less would suffice.What magnification would a telescope need to be to see the nearest star?
The sun is the closest star.What magnification would a telescope need to be to see the nearest star?Viewed from the surface of the earth all stars are too far away (except for our sun) to appear as anything except a bright point of light. Only the planets are close enough to be able to see their spherical shape.



However, through even a small telescope, even binoculars, you can see the spiral shape of millions of stars grouped together to form a galaxy such as the Andromeda Galaxy.What magnification would a telescope need to be to see the nearest star?
I'll wager that you don't mean the sun. So the nearest star although of less than perfect magnitude is Alpha Centuri. Best viewed from the southern hemisphere. A decent telescope with 200 power will do just fine. You can go to Space.com for futher information. You might have to register with them and ask in their discussion group to point out the nearest star viewed from the northern hemsphere.

Note: it will still view as a dot. No visible disk shape or other. Just a white dot.
