noone can actually physically visit the sun by landing on it cuz your spaceship would melt before it even got there. but yes they have sent robots to go get an up close look at the sun, but not too close.
If by humans visiting you mean , Which planet's have had humans land on that planet the answer is none. The only other place in space that humans have visited is the moon.
Sun Not the Only UnvistedThe sun is a star, but no, it is not the only object in our solar system that we have not yet vsited. There are many planets, too, although we have sent probes that have taken pictures of many of them.
it is too hot at the sun
As of 2021, only the Parker Solar Probe has visited the sun. It was launched by NASA in 2018 with the mission of studying the sun's outer atmosphere and its effects on space weather.
No its way to hot to even go close to the sun.
An astronaut never landed on the sun
NASA has sent spacecraft to all eight planets in our solar system, including numerous missions to Mars. They have also launched missions to study asteroids, comets, and the Sun. NASA's Voyager 1 spacecraft has even left our solar system and is now in interstellar space.
no but they have taken pictures
Humans Burn Near the sun. Humans can never just melt next to the sun especially when the sun is over 1 billion degrees Celcius.
Humans can die of skin cancer , or even a sun stroke.
No human being is present on the surface of the sun, nor has anyone ever visited there.
This question does not make any sense.
