Because planets are rather small on astronomical scales - or at least, when compared to stars, and not luminous like stars, it is very hard to see them at great distances. NASA's Kepler spacecraft, which was launched to detect planets within habitable zones of stars, detected in 2011 a couple planets orbiting a star roughly 1000 light years distance. The planets, designated Kepler 20e and 20f, are part of an unusual solar system, and are roughly Earth-sized and 'rocky' but orbiting their host star within the distance of Mercury to our Sun, which would make them too hot for life.
light years and then some ;-)
It is a planet which, as scientists claimed, has traces of water which may be favourable to life. This planet is 33 light years away.
From 3000 light years away, with a big enough telescope, you would be able to see the Sun. As a very dim star.
The closest habitat planet is Zeni X2 its orbiting a red dwarf about 2541 light years away from earth.
Outside of our solar system the nearest planet is 10.5 light years away orbiting the star Epsilon Eridani.
Goldielocks is about 20 light years away which is about 70 years
if by lights you mean light years, no planet in our solar system is that far away, however, the closest star, aside from our sun, is about 4.2 light-years away Proxima Centauri.

You are seeing it as it was 1,000 years ago.

The planet Mars is approximately 13 light minutes from the Sun.
If the estimated size of the universe is correct and that planetary bodies circle most stars then it is approximately 13.5 billion light years away.
In our Solar System the planet furthest from the sum is Neptune because pluto is no longer a planet. The furthest exoplanet is found so far it is an estimated 17,000 light years away
