At 5,500 degrees celsius, life on the surface of the sun would be rather uncomfortable. NASA has done the next best thing: Just last week NASA's Parker Solar Probe came within 18.6 million kms of the sun. At it's closest the probe is planned to reach 6.2 million kms from the sun, where temperatures will reach 1,370 degrees celcius. (http://bit.ly/37Zl8hS, http://bit.ly/36SLW1M, http://bit.ly/2Oqebi2)
