Think of a moth flying around a street-light, and you're standing 1/2 mile away
trying to see it. It's so small, and always so close to the bright light, that it's
tough for you to pick it out of the glare.
Mercury isn't much bigger than Earth's moon, and its orbit is the smallest of the
known planets. From where we are, it always appears so close to the sun that
it never rises until just a short time before the sun, and it always sets just a
short time after the sun. It's tiny, and it's never up when the sky is good and
dark, so it's always tough to pick it out of the sun's glare.
Yes.
Yes, Earth can be seen at night without a telescope. It is visible from space station and other spacecraft. However, it is not visible to the naked eye from the surface of the Earth at night.
No because it's to far
Pluto's magnitude varies depending on its position in orbit, but is never brighter than 13.65. The dimmest objects visible to the naked eye under perfect conditions are about magnitude 6.5 (the lower the number, the brighter the object). Pluto is about 1000 times dimmer than this. The faintest objects visible with the aid of binoculars are about magnitude 9.5. Pluto is still over 50 times dimmer than this. A telescope would be necessary to see Pluto.
No. Eris is too small and too distant to be seen without a powerful telescope. That is why it was not discovered until 2005.
Yes, Mars can be seen at night without a telescope. It's a "naked eye object".
1. Pluto is small. 2. Pluto is VERY far away.
No. No. You need a telescope to see Neptune.Nope... Neptune cannot be seen from the Earth without a telescope.

Often. In fact, it can often be seen at night without a telescope; it's fairly bright.
Yes
Yes.
Yes. If you know where to look, you can evensee it without a telescope, day or night.
Earth does not need a telescope, look down.
