Without protection, we cannot touch stars directly because they're too hot!

A lot of stars - the ones that actually glow - have temperatures in the thousands of degrees, and we would be burned away completely before we even reach the surface. We would probably be able to touch some of the dwarfs, but these are not really stars because they're too small to support the process that lets stars generate light and heat even though they might have formed in the same way that stars did. The coldest one we know is called WISE 0855-0714, which we think is between -55 degrees and 8 degrees, so if we had the right equipment, we might be able to go to its surface.

Hope this helps!
