Question

Astronomy

If the resolution of telescopes is increased sufficiently, then by the reflection of light from planets / asteroids in other star systems, it will be possible to see the solar system in the past?

Answer 1

Everything that we see through a telescope is the past, because the light travels from the object for some time, it can be millions of light years, depending on the distance and power of the telescope.
From the sun, the light comes to us for 8 minutes, i.e. you see the sun as it was 8 minutes ago.
If the light from the sun went into the asteroid, reflected from it - you see the asteroid, but not the sun, therefore, I think that if the asteroid does not have some kind of mirror surface, such as ice - then no, we cannot.
But this is so, reflections of the incompetent.

Answer 2

I believe that this is possible only within the solar system (before the heliopause), because further, the light is strongly scattered, and the reflection from any "polished" space object (even if there is one, which is highly unlikely) will be blocked by any nearby star.
