Which planets would we most likely be able to see in our night sky with no telescope?
You can see the six ancient planets without a telescope when they are visible, and in theory you can also see Uranus in perfect conditions. Neptune needs a moderate-sized telescope like a 3" refractor.
Is there an asteroid that is 300000 miles long?
No. And even then, something that large would not be conisdered an asteroid. Such an object would be more than 3 times the diameter of Jupiter, the largest planet in the solar system.

Why has only six planet been discovered by late 1700?
Only the ones that are visible to the naked eye were discovered until Uranus was discovered in 1781 by William Herschel using a telescope in a systematic search of the sky. Uranus is theoretically just visible to the naked eye but no-one had noticed it. Neptune is dimmer by 2-3 magnitudes.
Why is neptune the only planet you can not see without a telescope?
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.
What 3 properties do telescopes have thataid astronomers?
Telescopes focus on certain objects that are not visible from the naked eye, they help astronomers develop new theories because they are able to see more, and they are instruments that help astronomers prove theories true/false.
What planet can not be seen from Earth?
The planet Neptune, due to its great distance from Earth, cannot be seen without aid such as a pair of binoculars or a telescope. Uranus, though very dim, can sometimes be made out with the naked eye. All of the other planets are visible with the naked eye.

How many light years out can your telescopes look out in space?
With the naked eye, you can see stars up to about 1000 light years away. You can also see the Andromeda Galaxy. That's about 2.5 million light years away. That's the most distant object visible to the naked eye. Binoculars show it easily. With a 3" refracting telescope can see stars down to at least magnitude 9, plus some galaxies beyond Andromeda. The biggest telescopes can see to over 10 billion light years.
Is Mars visible from the earth without using a telescope?

How bright is the constellation phoenix?
Not very. The brightest star Alpha Phoenicis [See Link] has an Apparent Magnitude [See Link] of only 2.6. For reference. The brighter an object appears, the lower the value of its magnitude. Apparent Magnitude -12.6 (Yes negative) = The brightness of a full moon. Apparent Magnitude 3 = Faintest stars visible in an urban neighborhood with the naked eye.
How are galaxy's found?
At least 3 or 4 galaxies can be seen with the naked eye. Other galaxies can be seen if you watch through a telescope. Basically, in any direction you look, there are galaxies.
