Since KSP2 does not yet have heating, I decided to try to get into low sun orbit

As it was just a science experiment, infinite fuel has been used...

But in the end I achieved this tight orbit!

I tried to land on the sun as well for the fun of it. The surface at 0 m is not solid. Currently debating if I wanna wait the 30 minutes it takes to get to the centre of the sun.
