No. Saturn is a planet, not a star. To the naked eye, it LOOKS like a star, but planets are actually quite different from stars.
Yea. You can see the light reflecting off a planet and they look like stars. You can tell the diff. by if the 'star' you are looking at twinkles then it is probably a planet.
venus
no.
Mercury, Venus, Mars, Jupiter, and Saturn can be seen with the naked eye.
It depends on where the planets are in their orbits relative to Earth. In many cases the first object you see may be a planet as the five planets visible to the naked eye are brighter in our sky than the stars.
The sun is a star, not a planet.
Neptune is the only planet not visible with the naked eye, though Uranus is extremely dim and hard to spot.
No spacecraft was needed in order to discover the planet Mercury. It's a "naked eye" object, and has been known as a morning-star/evening-star since ancient times.
Yes. Mars is even visible in the night sky. It looks like a reddish star to the naked eye. We have sent several probes there.
