Mars' atmosphere is 95 % carbon dioxide, nearly 3 % nitrogen, and nearly 2 % argon with trace quantities of oxygen, carbon monoxide, water vapor, ozone, & other trace gases. The average temperature is about -55C or -67F but can range from -133C or -207F at the winter pole to almost 27C or 80F on the day side during summer. Orbiting 227,940,000 km (1.52 AU) from Sun, the Martian year is nearly 2 Earth years, while its day is only about half an hour longer than Earth's.
Mars has 2 tiny satellites which orbit very close to the surface, Phobos & Deimos.
This Image of "The Red Planet" is a composite of Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) daily global images acquired at Ls 193° during a previous Mars year shows the Tharsis face of Mars. Ls, solar longitude, is a measure of the time of year on Mars. Mars travels 360° around the Sun in 1 Mars year. The year begins at Ls 0°, the start of northern spring and southern autumn.
After the Red Planet, Mars, we travel even farther out to the giant planet, Jupiter.
