Many man made objects are visible from space. Large airports and large dams are common. The Great Wall of China cannot even be seen from a fairly low orbit around the Earth. Despite looking carefully for it, the astronauts are unable to distinguish it from the landscape as it blends in too well with the area around it.
Found it out myself - it's the Huygens Probe: with a diameter 1,3 metres, it landed with a parachute on Saturn's moon Titan on January 14, 2005. It has captured the only images from a planetary surface beyond Mars and Venus.

Sedna is the most distant solar system object discovered so far. It is about three times farther away than Pluto currently is. Because it is so far away, scientists are not sure if it has enough mass to be classified as a dwarf planet.

a mirage
an ultimate object or aim.
You have two eyes, away from each by about 6 cm. The object placed nearby makes a larger angle to both eyes as compared to distant object. From that angle, you make out the distance of the object from you. Stars are too far away for human eyes (or any animal eyes, for that purpose.) to make smaller or bigger angle. They all make the smallest possible angle witch can be recognized by naked eyes and so you can not differentiate between near or distant star. All of them are distant objects for human eyes.
