I think several people above have answered the question. The only thing that I would add is that, if you're at all interested, I would advise you to get yourself a telescope and check them out for yourself.
With the naked eye, the visible planets look just like stars (with the exception of Venus, which you can sometimes see as a crescent).
Get yourself a telescope, even a relatively small one, and it's a whole new ball game.
As a kid I had a 3.5 inch refractor and that was easily enough to resolve Jupiter and Saturn. They were still small, but you could see Jupiter's red spot and Saturn's rings. It was pretty awe inspiring when I saw them for the first time.

First the sun is a star not a planet. Planets you can see well in order of brightness are Venus, Jupiter, Mars, Saturn and Mercury.
With a very dark sky you can just see Uranus. I am not going to say any of the endless jokes about Uranus

Mercury, Venus, Mars, Jupiter, and Saturn are all quite bright when favorably positioned. Venus, Jupiter, and Mars, when close to opposition, will outshine any star. Saturn and Mercury rival the brightest stars, though Mercury stays so close to the Sun it's difficult to get a good look at. Under very dark skies, Uranus appears as a star near the limits of visibility.

surprising, there are 5 planets you're able to see with the bare eye specifically: Venus, Jupiter, Saturn, Mars and Mercury. lots of the time while Venus shows, it is the brightest merchandise interior the sky. it is interior the morning or night. For 8,5 months it is common because of the fact the Morning megastar, then it disappears at the back of the solar for a pair of month to re-look because of the fact the night megastar, lower back for yet another 8,5 months. Mercury on the different hand you are able to in basic terms see the two at nightfall or daybreak, customarily after consulting a visibility table. the explanation for it is because of the fact it is the closest planet to the solar. With the untrained eye all planets will look in simple terms like stars, yet once you employ even the finest binoculars, you will see that planets don't have a similar twinkle in them because of the fact the celebrities. that's because of the fact planets mirror the suns easy, the place as stars emit their very own easy. because of the fact the planets are in orbit around the solar - like the earth - they look each and every so often larger and each so often smaller because of the fact their orbits selection from earth's. on each and every occasion Venus is shining nonetheless it 's the brightest merchandise interior the sky, so vivid which you will discover it lots of the time while the sky is lit up at nightfall or daybreak. for the time of daylight hours it is invisible nonetheless. under perfect circumstances a 6th planet, Uranus, can be seen with the bare eye - yet actually by using binoculars. to locate it in spite of the undeniable fact that, one has to comprehend the Zodiac constellations ok, because of the fact it will be the megastar that "does not belong to the constellation". on the different hand you are able to seek for suggestion from a visibility table. desire it enables

The moon and sun of course are not planets.
You can see Mercury, Venus, Mars, Jupiter and Saturn from the Earth.
Uranus and Neptune need telescopes to be seen. Mercury is also difficult to spot because it is so close to the sun and is fairly small so it is frequently outshown.
Venus is the (appearent) brightest object in the sky (aside from the moon and sun of course). You can spot it right around sunrise and sunset fairly near the sun.

Well, the moon and the sun aren't planets, but I think you can see Mars and Venus, although Venus often gets mistaken for a star.

Mercury, Venus, Mars, Jupiter, Saturn. Get a good sky map and they will let you know when you can see them and where.
The moon is not a planet and the sun is a star.

Check out the site below,
By the way the Sun is a star, and it is possible that the moon is a planet. (That`ll put the cat among the pigeons)

Mercury, Venus, Vesta a minor planet only just visible, Mars, Jupiter, Saturn, Uranus is just about visible to many people, but like with Vesta you need to know where to look, as they appear like faint sixth magnitude stars only.

Almost all the planets are visible by the naked eye, but most of them appear, simply, as stars.
Mars is, probably, the most recognizeable by the naked eye, due to it's red color.
