Actually, with a knowledge of where to look (check any almanac) and good seeing conditions, you can spot five of the other seven planets with the naked eye: Mercury, Venus, Mars, Jupiter, and Saturn. Uranus and Neptune wold require a telescope. Venus and Jupiter have reliably good stretches of viewing in most any year. Mars has very good years, and not-good-at-all years (2011 and most of 2012 are poor for viewing Mars). Saturn will have a good year this year. Note that seeing the rings at will require a telescope, though - a 60mm at 170 power will do it.
You can see all of them in the sky at night.
Because the sun shines on them and illuminates them, exactly the way you shine a flashlight on a rock in order to see it at night.
The effect is that everything in the sky appears to rise from the eastern horizon, cross the sky in about 12 hours, and set in the west. That goes for the daytime sky too, as well as for the night one.

Mercury
In Florida's western night sky, you can typically see Venus and Jupiter. These two planets are bright and easily spotted with the naked eye. Venus is especially prominent due to its brightness, often referred to as the "Evening Star".
You can see five of them in the night sky when it's clear, one of those also in the daytime sky if it's clear and you know exactly where to look, and another one at any time of the day or night even if the sky is cloudy and it's raining.
In the night sky. Jupiter is usually visible, as well as Mars. Venus is visible in the early morning.
using your eyes
Every time they are there .We can see a body if light falls on it or it emits lights.So planets are seen at night, but at day time their intensity of light become very less than the Sun ,so they disappears.However when the moon eclipse the sun totally we can see them.
Venus is the brightest planet in the sky. It is often referred to as the "evening star" when visible in the western sky after sunset or the "morning star" when visible in the eastern sky before sunrise.
Yes. To date scientists have discovered well over a thousand planets orbiting other stars. It is believe that a large portion of the stars in the night sky have planets.
