The answer is different for each hour of night, for each night of the month,
for each month of the year, and for December of each year.
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.
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.
In the night sky. Jupiter is usually visible, as well as Mars. Venus is visible in the early morning.
Saturn is the planet that has visible rings and lots of moons. There are a few other planets.
The planets most certainly ARE visible in the northern hemisphere.
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.

The planets visible near the moon can vary depending on the time and location. However, some common planets that are frequently seen near the moon are Venus and Mars. Check a stargazing app for real-time information on which planets are currently next to the moon from your location.
All of them do, Saturn's are the most visible.

Planets do not align in the sense of forming a straight line. While planetary alignments can occur, they are not rare and do not have any significant impact on Earth. The last general alignment visible from Earth occurred in 2000, and the next similar alignment is predicted in 2467.
