Which planet has the most spacecraft landings?

Mars has hosted more successful spacecraft landings than any other planet besides Earth, with many landers and rovers from multiple nations. Beginning with the Viking landers in 1976, spacecraft from the United States, the Soviet Union, China, and others have reached the Martian surface. Robotic missions such as Pathfinder, Spirit, Opportunity, Curiosity, InSight, and Perseverance have greatly expanded our knowledge. The planet’s combination of scientific interest and relatively accessible atmosphere makes landing possible, though still difficult. Mars remains the main destination for surface exploration beyond the Moon.
