Depending on the time of year and its position in the sky, Mars can be seen from Earth with the naked eye or in more detail with a small telescope. To the naked eye, Mars appears as a bright red star. With a telescope, observers will be able to see things like the polar ice caps, clouds and impact craters.
Mars is approximately 39.9 million miles from Earth. There are 668 Earth days in one year on Mars, and it experiences seasons similar to Earth's seasons.
Mars is a very dusty planet with a harsh climate. Scientists do not believe the planet could sustain human life due to its environmental conditions.
