There are five planets visible to the naked eye; Mercury, Venus, Mars, Jupiter and Saturn. However, Mercury and Venus are interior planets (closer to the Sun that we are) and are never seen in the "full" phase.
Mars, Jupiter and Saturn are never seen in the "new" phase, because they never pass between Earth and the Sun.
Note: This is requirement 5.1 for the Astronomy merit badge.
the 5 most visible planets are the biggest planets such as jupiter saturn and mars pluto is to small and murcury isnt visible due to the suns rais.
Yes, because it must be very large in order to attain the resolution of optical telescopes.
They are both visible and inside the solar system.
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.
Calcium hydroxide is used to test for carbon dioxide because the product of the reaction, calcium carbonate, is insoluble, and easily visible.
KEPLER
No. You cannot conclude anything about a shape which is not visible.
The visible hair cells are in fact dead, only the root in the skin is alive.
There is enough sunlight reflecting off them and reaching our eyes.
The planets most certainly ARE visible in the northern hemisphere.

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.
It is yellow in colour. It's a safety feature, as yellow is bright and highly visible.
Yes, because it must be very large in order to attain the resolution of optical telescopes.
Venus Jupiter
No, planets are not stars. Stars are huge balls of burning gas, planets are not. At certain times, there are 5 planets that are visible with the naked eye in the night sky. Some of these are similar to stars but much closer. They are Mercury, Venus, Mars, Jupiter and Saturn. See the related link for more information.
