There are five planets that are generally visible to the naked eye.
In September 2009, Mercury and Saturn are too close to the Sun to be seen.
Jupiter rises just before sunset, and is visible most of the night.
Venus and Mars rise a couple of hours before dawn, and are easily visible in the eastern sky before the Sun rises. Venus is the incredibly bright one, and Mars has a distinct reddish tint, so they're both fairly easy to pick out.
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.
In ancient times, the five planets visible to the naked eye were Mercury, Venus, Mars, Jupiter, and Saturn. These planets were observed and recorded by ancient civilizations such as the Babylonians and Greeks.
Mercury
the naked eye determines if it is visible.
The five planets visible to the unaided eye are Mercury, Venus, Mars, Jupiter, and Saturn. These planets are typically visible at different times of the year and can be easily spotted in the night sky without the need for a telescope.
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.

Venus Jupiter
Yes, Mars will be visible in the morning during the month of August.
They are both visible and inside the solar system.
In August 2010, the planets Venus, Mars and Saturn are visible low in the west at sunset, while the planet Jupiter rises in the east at about 9 PM.
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.

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