– Space is a vacuum with zero atmosphere, so heat does not transfer well. Could we get really close to the sun because of that?

The basic idea is not wrong. Put a shield between yourself and the Sun, and you’re good to go. The heat from the Sun won’t wrap around to get to you.
Examples: The Webb telescope has a shield made of multiple layers of *foil*, that has allowed it to chill down to a few degrees above absolute zero. The [Parker Solar Probe](https://en.wikipedia.org/wiki/Parker_Solar_Probe) has gotten to within ten million km from the Sun without being damaged.
