Has anyone ever been to the Sun?
No. Outside mythology, no human has ever attempted to travel to the Sun. The main reason is fairly obvious—it's too hot. Even in a well-protected spacecraft, you could only get within about 2 million kilometres (1,300,000 mi) before burning up.
It's also surprisingly difficult to get to the Sun. The way physics and orbits work, it's easier to get to the outer Solar System than the inner parts. That's one reason we don't dump rubbish by letting it "fall" into the Sun.
