Mars and Venus
The Earth is the only planet people have landed on. Humans have landed on Earth's Moon and have landed robotic probes on the surfaces of Mars, Venus, and Saturn's Largest moon Titan.
The inner planets are different from the other planets mainly because
Other than the earth, so far we've landed people on the moon, and landed robot probes on Mars and Venus and Mercury. The condions of the out planets mean a landing there is not likely soon, but we may be able to land on some of their moons.
EarthThe moonRobots built by humans have landed on Mars, Venus, and Saturn's moon - TitanProbes have been sent to all planets in the solar system as well as several of the gas planets' giant moons, and some comets.
There were 6 separate successful moon landing missions, carrying 12 men to the surface.
The two VIKING probes arrived in Mars orbit in 1976 when they started sending photographs back to Earth. The two orbiters continued sending photographs and the landers conducted experiments on the planet's surface until they failed as follows:Viking 2 Orbiter: July 1978 Viking 2 Lander: April 1980 Viking 1 Orbiter: August 1980 Viking 1 Lander: November 1982.
Nobody has landed on Jupiter. The only place people have landed is the Moon.
As of now, the only planet people have walked on is Earth. All other planetary bodies in our solar system, such as the Moon, Mars, Venus, and others, have not been visited by humans on foot. NASA's Apollo missions successfully landed astronauts on the Moon between 1969 and 1972, making it the only celestial body besides Earth that humans have physically explored.
It was the day people landed on saturn
None. The only object other than Earth on which people have set foot is the moon. It would be impossible to walk on Jupiter as it does not have a solid surface.
People choose to keep photographs in an album to preserve the quality of the photographs, to be able show them to guests and visitors, to have something to hold on to and look back on.
A long time ago- around Christopher Columbus's time- people use to think that the Earth was a cube. Scientists now know that the Earth is a sphere. There is also evidence that it is if you don't believe that - but i highly doubt that. Astronauts that have landed on the moon have seen the Earth and have taken photographs of the Earth. They show that the Earth is a sphere. All the planets that the scientists have discovered so far have all been spheres.
