It depends on where you are. try - http://www.glyphweb.com/esky/wheel.html
During the evening of January 29th, 2009, in Lynn, Massachusetts, you would have been able to see the planets Mercury, Venus, Mars, and Jupiter in the night sky. These planets would have been visible at different times after sunset, so it's best to check a stargazing app or website for specific viewing times and locations in the sky.
Planet Gorgone
I'm not entirley sure but this website might help :) www.mauiastronomyclub.org
The planets most certainly ARE visible in the northern hemisphere.
There are generally a couple of planets visible every night of the year. Which planets will be visible and when depends on where each of the planets (and the Earth itself) are in their orbits. Here on August 28, 2009, for example, Jupiter rises about sunset and is brightly visible all night. Venus and Mars rise before dawn. Saturn and Mercury are not visible this month, because they are too close to the Sun to be seen.
Following the August 24, 2006 reclassification of Pluto as a "dwarf planet", there are 8 actual planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune) and (as of January 2009) 5 dwarf planets (Ceres, Pluto, Haumea, Makemake, and Eris). As of January, 2009, the orbit of another dwarf candidate (Sedna) is still being verified.
Planets are visible in the night sky because they reflect sunlight. As they do not emit their own light like stars do, they rely on the Sun's light to make them visible to us here on Earth. The brightness and position of planets change as they orbit the Sun, making them observable at different times throughout the year.
Venus Jupiter
They are both visible and inside the solar system.
The five most visible planets (Mercury, Venus, Mars, Jupiter, Saturn) can often be seen at different times of the year depending on their positions in their orbits. However, there are times when some or all of these planets are visible together in the predawn or post sunset sky. Consulting a stargazing app or website can help you identify when and where to look for them in the night sky.
