The five planets visible from Earth without a telescope are Mercury, Venus, Mars, Jupiter, and Saturn. These planets are often visible to the naked eye and can be seen in the night sky from various locations on Earth at different times throughout the year.
The planets most certainly ARE visible in the northern hemisphere.
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.

Uranus
All of them do, Saturn's are the most visible.
Planet Gorgone
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.
