What planet can be seen with the naked eye?

Answer 1

Venus, Mars, Saturn and Jupiter are the most easily seen.

Mercury can also be seen in good conditions, but as Mercury is so close to the sun it only appears in the sky either just before sunrise or just after sunset, both when the sky is not quite dark enough, and always low down - so that it is not as well defined as the others.

Venus, being almost as close as Mercury to the sun is also seen before sunrise or after sunset (the 'Morning' Star or 'Evening' star) and because Venus has a white reflective cloud layer it always appears very bright - like a very bright star as opposed to Mercury which is fainter because its surface is non-reflective rock. Sometimes when Venus is at its most reflective in the sky, and when there is no moon in the sky nor light polution, Venus can even be bright enough to cast a shadow.

Mars appears as a very bright 'star' that is obviously red in colour - and can appear quite high in the sky depending upon your latitude.

Jupiter and Saturn appear as bright white 'stars' - again very high up in the sky like Mars.

There is one more planet - Uranus - that can be seen with the naked eye, although not easily. If the night is very dark, there is no light pollution and you know exactly where to look, Uranus can just be seen as a faint 'star'.

Neptune, however, and any objects in the minor planets that begin with Pluto, cannot be seen except in a telescope.

Answer 2

Mars, Venus, Saturn and Jupiter are easily seen with the naked eye.

Mercury is bright, but always low in the sky, so it's difficult to find, but easy to see.

Uranus can be seen, but requires PERFECT atmospheric and sky conditions.

The Earth, of course can be seen at any time.

Answer 3

The term "Jovian" in this context refers strictly to one planet - Jupiter. It has a number of moons also called Jovian or part of the 'Jovian system', but these are not true planets. Jupiter can be seen with the naked eye, but its moons require a telescope to resolve, as Galileo discovered.

Answer 4

All those that were known to the ancients, all of them up as far as Saturn. Theoretically Uranus is also visible to a perfect naked eye in perfect conditions but usually it needs binoculars, and it is visible just now (Dec 2014) near the star 96G Piscium.

Answer 5

Planets that are sometimes visible to the naked eye are:

1. Mercury
   
2. Venus
   
3. Mars
   
4. Jupiter
   
5. Saturn
   

Notes:

Some people with keen eyesight can also see Uranus.

Neptune is theoretically possible to see with the naked eye based on math calculations, but no one has ever seen it.

Answer 6

Mercury, Venus, Mars, Jupiter and Saturn are all visible with the naked eye. Uranus is also visible, but you have to have good eye sight, good viewing conditions and know where to look.

Answer 7

Mercury, Venus, Mars, Jupiter, and Saturn are all visible from earth to the naked eye. Some can only at certain times.

Answer 8

I know the moon is not a planet but that is the only thing close to a planet i know that you can see without a telescope.
