Can you see any planet in your constellation?

In our last class, we were talking about the Solar System and its bodies: planets, satellites, comets and asteroids. As I told you, ancient Greek gave the planets this name as they noticed how these bodies travel through the night sky. So, if you look at the sky night after night it is possible that you recognize a planet as a small point of light that changes its position between constellations (see the picture below). Every one of you have chosen your constellation and we are going to learn lots of things about them, about their galaxies, nebulae... But, what about planets? Is possible to see planets in every constellation? Could you see any planet in your constellation?  Those are our first questions.
But if you think that you can see planets only in some constellations... Which ones are these constellations? And why you can watch planets only in those regions of the sky? 
They are not easy questions, but I am sure that all of you are very clever. Please, send your answers as a comment. You will have extra points.
And here you have a picture from APOD. It's Saturn moving through the sky from August 2005 to September 2008.

    But, what about planets? Have a planet half fire half ice link :
    Is possible to see planets in every constellation? Not because Andromeda is far from the constellations.
    Could you see any planet in our constellation?can not because we need a telescope

    1. I am sorry but you are wrong. Of course you can see planets without a telescope, just with your eyes. Try again::

    1ºIs possible to see planets in every constellation? Planets can be seen in some constellation.
    2ºWhich ones are these costellations? ARIES:Jupiter and Venus, LEO: Marte.
    *Why you can watch only in those regions in the sky? Planets can be seen only in those regions of the sky, because there are closer sunligth

  3. Only in Aries and Leo? Probably not. Try again!!! Good luck!

    My constellation is Virgo.As in all the constellations that crosses the ecliptic, it is possible to find planets in this field. That is why it is one of the signs of the zodiac.

    The orbits of all planets are in a plane. For this reason the planets are on a line in the sky. this line is the ecliptic. You can see planets in a contelations only if the ecliptic pass for this constelations. I drawing the ecliptic in Stellarium and I see what constelations pass for the ecliptic. Aries, Taurus, almost Orion, Gemini, Cancer, Pisces, almost Cetus, Aquarius, Leo, almost Sextans, Virgo, Libra, Scorpius (my constelation), Ophiuchus, Sagittarius, Capricornus.

    Venus pass through Scorpius on 19 September 2014. Mercury aproximately 30 November 2014. Saturn aproximately 25 January 2015. Jupiter aproximately 26 November 2018 with the Sun and Mercury. Uranus aproximately 22 January of 2066. And Neptune in year 2136. I see this in Stellarium.

    You can see some planet in the constellations.I think that you can see planets in LIBRA,VIRGO,SCORPIUS,SAGITTARIUS,OPHIUCHUS,LEO,CANCER,AQUARIUS,PISCIS and CETUS.

  8. Hi I'm Esther , I chose the constellation of cancer and I think that there is no planet. But if it can serve you , I have found many stars , including the most important are : acubens , Altarf , asellus borealis and australis asellus tegmine .

  9. Hello my name is adrian and in my constellation , called Scorpion , we can see planets.

    Hello I´m Yurema, I choose the constellation LEO, I think that in this constellation there isn´t any planet.

  11. Hello!!! My name is María Bacigalupe. My constellation is Aries. You can see Saturno,Júpiter,Marte,the Sun,Venus,Mercurio and the moon in this constellation.

  12. hello my name is David balica.I think it can not be so because the planets move but the constellations do not move.

  13. There base constellations having boyero planets having the planet Arcturus (in estellarium can be seen) but mercury is not part of the constellation always or as the many other so if there planets in the constellations.

  15. My constellation is Capricornio and I think that in this constellation you can see Neptuno (The planet) from DENEB ALGEDI (one star)
