The inner, rocky planets are near enough to be seen with the naked eye. Jupiter and Saturn are very large and again can easily be seen by the naked eye. Uranus is large enough to be seen at a distance of approx 3 billion km. While Neptune is only slightly smaller than Uranus and it is 1.5 times as far as away so that it is not visible to the naked eye.
You could see Neptune from Earth with a telescope if you knew exactly where to look.
The planet that is 2,793,100,000 miles away from the sun is Neptune. This planet wasn't discovered until the 1840s because its the only planet that can't be seen from earth without a telescope.
Neptune is the only planet in our Solar System that requires a telescope to see it.All the others are visible to the naked eye.Pluto, which is still counted as a planet by many people, also needs a telescope.
Neptune has 13 moons and 5-6 rings. The highest winds in the Solar System are on Neptune. It was discovered using mathematics to predict where it should be. Only Uranus and Neptune have been "discovered" the rest are easy to see in the sky. You can actually see Uranus without a telescope if you know where to look and have good viewing conditions. A lot of people don't know that Neptune is the only planet that can't be seen without a telescope.
you can see neptune with binoculars, but you won't see anything but a small dot [:
Neptune is the only planet (including all dwarf planets) in our Solar System that cannot be seen with the naked eye. [See related question] Even with a telescope, it is difficult to see.
You can see Neptune with a telescope.
Neptune but only on a very good night i think
Saturn , Jupiter , Uranus and Neptune, all of the rings can be seen with a normal telescope, but not , Neptune you have to block out planet to see them.
Neptune was discovered using a telescope.Uranus was discovered with the naked eye, but because of it's slow rotation it was believed to be a star. Only with a telescope was it identified as a planet.
1. neptune is the only planet that is light blue. 2.neptune is a female planet. 3.neptune is the only planet that was named after someone
All of them. That's where they were discovered from. Only Neptune cannot be seen with the naked eye.
