Our Solar System A group of planets that orbits around a central star is called a solar system. Planets form from the dust and gas left behind after the birth of a star. This is our family of planets.
Postcards from Mars Other than Earth, Mars is the most explored planet in the solar system. Four robotic rovers have crawled over it surface, and 42 probes have orbited around it. This is a tour of the must-see sights on Mars.
