MARS IS NOT A STAR!!!! Mars is made from ROCK compared to a star which is a giant, hot, burning radioactive mass of hydrogen converting to helium. It is the 4th planet from the sun. The planets orbiting the sun (which is a star!) are as follows; Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune (notice how Pluto is not include as it was declassified as a planet in 2006) which coincidentally are not stars either! Jupiter, Saturn, Uranus and Neptune are made of gas, not rock. Furthermore, to prove my point that mars is a planet, here is a link to some pictures of the surface from the curiosity rover which just happens to be paying a 'visit'. http://www.space.com/16987-mars-rover-curiosity-photos-week-2.html
Mercury, Venus, Earth, and Mars are planets in our solar system that are made of rock. There may be many more in other star systems.
