Anything that is too far away or doesn't emit enough light. No planetoid can't be seen with the naked eye. Most stars, even the closest ones, can't be seen with the naked eye, since they are too faint to be seen - the stars that you do see have an above-average brightness.
Comets - such as the ones in the Oort Cloud - can't be seen even with telescopes, unless they happen to come fairly close to us. The farthest known galaxies can be seen with large telescopes, but the individual stars cannot be seen. Etc.
What else can I help you with?
What objects can be seen from earth because they produce their own light?
Cities can be seen from space.
What is one telescope that has seen Earth?
The Hubble Space Telescope has seen Earth. While its primary function is to observe celestial objects in deep space, the telescope has also been pointed towards Earth for calibration and testing purposes.

What keeps objects from floating into space?
The force of gravity between an object and Earth keeps objects from floating into space. Gravity acts as a force of attraction that pulls objects towards Earth's center, preventing them from drifting off into space.
Are objects in space affected by earth's gravity?
they can be yes.
How have space objects affected earth?
it is making scientist create objects to go out and study it
What is used to see space on earth?
You can't see "space". You can see objects in space, but space itself is not visible.If you did wish to observe objects in space, a telescope would help you to do so.
