The solar system from a distance of 45 light years

From Centauri Dreams.

Suppose we cloned the Earth and placed it around a star 45 light years away. And supposing the inhabitants of that cloned Earth launched the proposed NASA High Definition Space Telescope and pointed it at the solar system. What would they see?


A simulated image of a solar system twin as seen with the proposed High Definition Space Telescope (HDST). The star and its planetary system as they would be seen from a distance of 45 light years. (The central star is occluded by a screen)

I used to think we needed exotic technologies such as gravitational lensing telescopes to image extra-solar planets. Apparently not so.

Centauri Dreams is an excellent site, by the way.
